  • dude your tutorials are really helpful!

  • would you suggest someone to buy the cam your using vs a dslr or does your camera have rolling shutter problems?

  • i have a sony hdr cx 130 , its not really a prof cam , does anyone know how can i have a narrow depth of field with this camera , i have no control over the aperture , and i cant change the lens , all i can do is use the zoom , and change my distance , cuz i feel what ever i try to do it will still give me a wide depth of field which i dont want !

  • @deathschuck Move back, zoom in and focus on the subject.

  • This was probably the best depth of field tutorial I have watched on Youtube. Thanks.

  • Dude I love you...for real!!!! I been trying to understand DOF for the last year or so n its been a struggle was going to pick up a 5D to go with my 60D & 7D just so I can have better DOF but seeing this I really don't have to...this is getting saved to my phone..right now at 6:02am...lol

  • 04:02 a lens that can what? ahah jk. good info though

  • Great tut! I came across this great DOF calculator from Digital Rebellion webapps/ dof_calc.html It lets you input your camera type and all the variables to get your Depth of field!

    It is online and free! Keep up the good work!

  • you said my name is tomatoes hahaha

  • how i can get DOF using a kodak zi8?????

  • @kazikpl6 can't really..

    

  • thnx very much for this tutorial and spesificly on the explanation on the camera sensor in regads to DOF. This gonna save me some money considering that i'll rather buy the 7D or 60D instead of 5D

  • @djxclusivswiss Yup... I think the 7D and 60D are actually better for video than 5D. 5D was just simply the first good DLSR video camera but now there's other better options out there

  • Comment removed

  • Tom, great tutorials. I just picked up a cannon hfs 100. I consider it a semi pro camera, with many manual functions, and full 1080! Have you ever worked with this camera?

  • @1141Studios nope sorry

  • thanks for sharing....

  • Couldn't you have made this tutorial in the carribean? Poor guy was freezing his ass off while you experimented with all the variations!

  • @Karradaguy lol... i know... i was also freezing! :) next time i'll pick better weather

  • keep making these awesome tutorials

  • I'm using a nikon d3100 with 35mm F/1.8G lens. Since this is a prime lens is it possible to have a WIDER Depth of field to have everything in Focus with these lens? Since the aperture is lockedto 1.8g what would you suggest to have everything in focus?

  • Thanks man! I found this tutorial helpful as I am learning to master my 60D

  • Dude you seem to cover everything in film making! Good work, and thanks!

  • @Gonamez thank YOU!

  • Hi Tom - great video - the one thing you didn't mention/explain was when you had to back up to frame your subject with the cropped sensor camera to approximate the same framing of the full-frame sensor camera, that not only does the depth of field decrease slightly, but that THE BACKGROUND LOOKS VISIBLY CLOSER. Can you explain why this effect occurs? Is there a way to get closer to the overall look of a full frame sensor camera with a cropped sensor one? Just trying to figure it all out! THX!

  • haha this guy is fucking freezing!

  • loving your tutorials Tom atoes

  • Excellent, Excellent, Excellent. Man this is by far THE BEST TUTORIAL. Many can explain DOF for still photos, but they can't demonstrate how to do it with a video cam. without a doubt, I will subscribe and thumbs up the tutorial.

  • @Polcan99 The line basically appears as a choppy artifact everytime you move your camera. Do you know why it does that ?

  • I also noticed too. The colors between the 7D and the 5D MarkII are different. Why is that? :-D

  • @Polcan99 - What is that weird choppy line artifact I see at between 9:00 & 9:04

  • So why buy a full sensor HDSLR when I can do the same job with a smaller sensor?

    Maybe, a bigger sensor HDSLR will give me more resolution/defenition?

    thanks

  • @maltijien Bigger sensor simply means it's actual size... remeber BIGGER doesnt always mean better ;) It's about how you use it... and in this case I find many people are always jumping on Canon 5D when in fact that camera got more popular cuz it was the first DSLR to record good video... but now cameras like the 7D or T3i or the 60D are better and have more options. Size sensor is smaller, yes but it's still closer to actual size of a sensor that we used in 35mm films for over a 100 years.

  • @polcan99 tks man, this helps a lot.,,, so last and not less, why hdslr and not an hd camcorder?

    many thanks for your time :)

  • @polcan99 thanks very much, this was very helpfull ;)

  • @maltijien A Camera with a Larger Image Sensor will allow you to shoot With larger distances in your shot for instance an 8ft shot with a small sensor will result in a closeup on the object with a set depth of field that focuses on the object alone. if using a Large image sensor shot at 8ft using the same settings, will allow the "same depth of field but provide a wider shot. Also using a bigger sensor allows you to be more flexible with your shot as you can focus and zoom without changing DOF.

  • @LiteCastStudios thanks very much, this was very helpfull ;)

  • hey i likd ur tutorials its helpful but can u put up some tutorial for using handycam to get the maximum output from them ...like the dof nd stuff ..

  • u help me so much. thank u.

  • good stuff! glad you have a xha1 it makes it easier for me to follow since I own one too!

  • Very informative! Thank you for putting this together. I learned a lot.

  • Explained really good :) Many photographers should look this to get the thing with the

    settings :)

  • Hi :)

    what contribute to that colour tone difference btw the 5d and 7d footage?

    is it the settings on the actual camera or is it because of the sensor :D

    thanks =D

  • You are using a Canon XH-A1 I believe in your camcorder shots.

  • What is that green tape around your lense for?

  • @gskowal i use it for marking my focus points. Sorta like what you would use a follow focus ring for

  • @TomAntosFilms , Thanks for the reply!!! great idea!!! :)

  • @TomAntosFilms , btw. Your videos are supper helpful !

  • Fantastic! Thanks, Tom.

  • This was very very helpful. Thanks.

  • can you suggest a camera that has all these features but in sub $300?

  • @samus1225 no way lol, try some cheap dslr's

  • thanks for the great tutorial, I've been struggling to understand DOF for the last week or so now and this really helped clarify things.

    cheers! :D

  • But I see where hes coming from when it comes to sensor size. Funny, there was no mention of distance from the background. Great video either way.

  • A great video if you want to learn about DOF. I somewhat disagree with this video though. "Focal Length" and "distance from your subject" are to closely related to each other to be treated as separate factors.... that is if you plan on actually framing your shot (WS, MS, CU).

  • Comment removed

  • thanks for all the inform man...i have a Canon 60D n i used the inform you give and it work perfect for my video shooting...

  • You the man, that was a long ass but very educational tutorial. Thank you Tomatos!

  • Thank you very much

    I really liked this tut

    and enjoyed it

  • Thank you very much

    I really liked this tut

    and enjoyed it

  • If you have a video camera, you must zoom in all the way but how could you zoom in if you must be as close to the subject as possible.

  • @skud14 You should then zoom in as much as you can. To get narrowest possible DOF you should be as close as possible and zoom in as much as possible and open the apreture all the way. That's why in macro photography you get very, VERY narrow DOF. Sometimes as narrow as 1 milimiter cuz the camera is so close yet you still use a zoom lens to get a close up of the instects, flowers etc.

  • Thanks, man :) I've into photography for 4 years and I still needed to watch this video :)

    I love Canada too :D

  • Lord, the weather really looks horrible there. 

  • @wheresmystuffmovie You have no idea! I love Canada, but not the Canadian winters here :(

  • @polcan99 I live in Guayaquil - Ecuador so here is like a paradaise for you.. ¡Gracias por los tutoriales! They are very good!

  • @dnsalvatierra I love Guayaquil! I go there every year... maybe we can do a video together next year when I come to visit.

  • @polcan99 For me will be a pleasure, I work in a Studio Production called "In House" into the "Universidad Casa Grande"... This University is one of the best here in Ecuador, you know here in Ecuador we suffer for the bad education in the Audiovisual Production area but is a lot of fun have a University with "Audiovisual and Multimedia Comunication" career. So well, you are welcome to come to my office to talk about the little world. Some day I will glad to visit Canada.

  • @dnsalvatierra Sorry about my english!

  • @dnsalvatierra I'd love to visit... send me your contact info and address using the contact form on my company website tlapro com so that I can get in touch with you next time I'm in Guayaquil

  • @polcan99 Ok, I already did!

  • Will you be doing a video that discusses the relationship between Arpeture, ISO and how to avoid getting grain? I like shooting on the fly and I've been trying to achieve nice night shots of New York City with my 7D. Day time and Times Square of fine, but when I film darkly light streets during the night, I have to pump the ISO up and that transfers to grain.

  • I learned a lot from your video. Thank you so much!!! I want to use Telephoto Lens to make the image into deep focus. Is it difficult? Japanese Director Akira Kurosawa was using Telephoto lens, and images in his movies are deep focused.. I want to try. Please teach me How..

  • @kojisugawara777 Its a bit harder but possible. If you want deep focus when using a long telephoto lens then you can use the other two things that affect the depth of field that I discuss in the video. Go as far away from your subject as possible and close down the aperture as much as possible (use the largest f stop number)

  • @polcan99 Thank you so much!! i will try what you taught. and I will keep watching your videos. It is helpful for me. Thank you..

  • polcan99. thank you for the tutorials. i have improved tremendiously because of you. thanks for making such good information available for free. God Bless. from Nigeria.

  • Nice tut. The only thing that would make it better is to have a hot chic instead of a stubble bearded dude. :) ...and I know you got access to the hot chics.

  • @onjoFilms LOL... you are correct! I will start bringing them back out in future tutorials as the weather here in Canada gets better. Right now all the girls are hiding inside :)

  • Wow. Skin tones on the 5D are SO MUCH nicer than the 7D.

  • @bbcasting That's actualy becuase of the custom picture styles. If you were to set the picture styles up the same on both 7D and 5D then they look almost identical. In this video I just didnt have time to do that while filming.

  • @polcan99 Can you send me (privately if you want) your picture settings that you used on the 5D here? The colors/skin tones look GREAT!! Do you think that you can get the same result on the 550D color wise? Seems like skin tones are always so reddish for me with the 550D and I haven't been able to find the perfect custom settings. Thanks for the tutorial videos. They are all extremely helpful and informative.

  • @polcan99 Can you send me the picture styles (privately if you want) that you used for the 5D here? The colors and skin tones look GREAT!! Do you think that one can achieve the same result (or close) using the 550D? Skin tones always seem too reddish for me and I haven't been able to find custom picture styles that works nearly as good as this. Thanks for the tutorial videos too. Very helpful and informative!!!

  • Hey, anyone, i want to buy a camera that has a 1/3 image sensor. its a camcorder i'll use to make short films. will i get good depth of field off of that. i understand compared to dslrs it will be a lot worse but will i get anything?! thanks

  • @wonderwall135 Yes, you can still get a small enough depth of field with such a camera. Check out the example I show at 10:09 in this video. It's also shot using a 1/3 image sensor camera.

  • Hello man... great tutorials! Congrats!

    But i wanna share some information about big and small sensor you didnt say and, for me, its the most important of them.

    The smaller is the sensor, the smaller is the "dinamic range".

    Cameras like Phase One, Hasselblad, has a bigger dinamic range and the images is like a HDR 35mm image, where you increase the black areas and decrease the overexposured areas.

    The background on your exemple is the same, but the black on the jacket has a big diference.

  • hello wondering if your film with the two hours of tutorials is still available also if it s available on amazon can is it available anywhere else as amazon sometimes on some product will not post to ireland

  • @superflynn290483 Yes, the dvd is still for sale. You can buy it by clicking on the STORE link on my youtube channel page

  • Very informative video, Tom. This is great work and extremely useful to new, aspiring directors, like me. Keep up the good work, sir, and keep 'em coming.

  • The sensor size definitely has a huge part of the apparent DOF in images. Why do you think the DSLR craze is so big? Because we can achieve great DOF which we just cannot achieve with smaller sensor cameras like the XH A1. Try to shoot something wide for example inside with the XH A1 and get a small dof. Just isn't possible. With the Canon 5d it is very possible and easy.

    Take a 50mm lens at f1.4 and shove it on an XH a1 and frame it so it matches the 5d you will see that the DOF is not same.

  • This was a great tutorial, very informative for a nob like myself. One thing though, when doing the comparison of the 5D to the 7D to illustrate the crop factor point, how far back did you have to move the 7D to match the full sensor framing of the 5D?

  • @ryanmkincaid Thnx... I moved back a few more feet, sorry I dont remember the exact distance.

  • @polcan99 No problem. But yes this was an excellent video. Your vids usually are but I think that I'll be taking more from this single vid than the others you put up. I really want more like this. I have a 7D and besides the hack that allows you to adjust audio on the 5D the crop factor was something that troubled me. Knowing that it's only a few feet that will allow me to match a 5D is def something that will let me sleep better. Can't wait for the next one.

  • @polcan99 Hello man... great tutorials! Congrats!

    But i wanna share some information about big and small sensor you didnt say and, for me, its the most important of them.

    The smaller is the sensor, the smaller is the "dinamic range".

  • @polcan99 @polcan99 Hello man... great tutorials!

    Just to share with everybody:

    Its true. Small or big sensor doesnt change depht of field, but changes the "dinamic range" and its very important.

    Thats one of the things why 5D is better than 7D for videos. Look in you exemple on the final of this video, the background is the same, but the jacket has a big black color diference.

    And for that question, easy, move 1.6x the distance closer from the 7D to 5D... rsrsrsr

  • Fair play to ye guys i have been doing some shooting outside in -15 weather conditions its tough going,Again another fantastic tut looking forward to the next Niall ireland

  • I didn't watch your video to the end the first time, you explain everything very well. I'm sorry. Excellent job- a very informative, well-presented video. Please keep them coming.

  • The same lens on two different size sensors keeps the same DOF. The real world situation would be different lens on the different cameras to achieve the same shot composition at the same camera position. Try that on your two cameras to achieve the same shot with the same exposure without changing the ISO or shutter

  • Moving the camera creates a different shot. You have a smaller area of the background. This effective blowup of the BG also means that it appears more out of focus. Changing camera position assumes there is the space available and creates a more wobbly, difficult to track/pan situation.

  • Thanks very much for this tutorial! Very well done and informative.

  • This tutorial is bad ass TOm thanks man!

  • Comment removed

  • Another great video. I love that you use the XHA1 in some of your tuts, as that is what I have. I've been experimenting with DoF recently and this really helped. Thanks!

  • The reason why the size of the image sensor affect the depth of field is a consideration of the desired field of view- a very important consideration.

  • There is a lucid explanation for you about how sensor size affects depth of field right here. news.cnet.com/8301-13580_3-980­2758-39.html

  • @polcan99

    You rock-- I've learned TONS from your videos. Now- if I could only get that cinematic feel every time I frame my shots! I tend to obsess over it-- specially since right my project takes place in a car-- and while having a Gecko mount helps there are some shots that would be nice from outside of my car but alas even with a circular polarizer the tint on my windshield is too dark. But what I've been doing to get the shots I want is studying movies like, Fandango happen in a car.

  • To see that sensor size doesn't change the DOF do tests with a a pin hole camera. Or an old 35mm film camera you don't care about, remove the back & replace it with paper to view the projected image.. make the paper smaller or larger & the cirlce of confusion stays the same... then change the 3 factors I mention and you will see it change. Don't get me wrong. I'm not saying larger sensors aren't better if you want to achieve shallow DOF, but they are not what actually causes the changes.

  • @polcan99 - That's true! The sensor size doesn't directly affect the depth of field. Though, it is very important for the people watching your very informative videos to realize that it is much easier to get a shallow DOF with a big camera because of how the crop factor of the lens affects the field of view. In order to get a workable field of view with a small sensor camera, you need to use a very wide lens, resulting in a deep DOF- I just made a vid about this. Thanks for the great vids!

  • Sensor does indeed affect depth of field. Read up

    I've been a Letus Extreme user for a several years because 50mm 2.8 on my little 1/3 cmos camera looks very different to the same focal length and aperture via a Nikkor lens attached to my Letus, which gives a film 35mm frame size.

    Chip size affects DOF very notably. Hence the invention of lens adapters like the letus in the first place, and the subsequent popularity of DSLRs.

  • @jazzemagic Perhaps you should read up. Im not saying it's not easier to get a shallow DOF with a larger image sensor, but it's not the actual sensor size that affects that... The reason you think sensor size affects depth of field is because you've been using various focal lengths, apertures and subject distances with different sensor size cameras, because the framing changes.

  • @polcan99 "For an equivalent field of view, a Canon APS-C crop sensor camera has at least 1.6x MORE depth of field that a 35mm full frame camera would have - when the focus distance is significantly less then the hyperfocal distance (but the 35mm format needs a lens with 1.6x the focal length to give the same view).give the same view)."

  • I would argue that just as a sensor doesn't technically affect the DoF, the focal-length too doesn't change it. Focal length just enlarges the projected image and the sensor-size crops it. But they both affect working with DoF when you want a certain perspective and framing with one sort of DoF because of where you have to place the camera to get it.

    I would also argue that most of the time, super-long lenses works against the DoF formula since you have to go so long way away from the subject.

  • @jmalmsten Yes... if you use a long lens then the DOF does physically get more shallow. But if you want to achieve the same framing then you'll have to move away on a long lens thus again widening the DOF cuz you are increasing the camera to subject distance. So larger image sensor makes it easier to achieve shallow DOF but not what actually causes it. It's the circle of confusion that does. you can find more technical explanation in most encyclopaedias

  • Hey Polcan, I have a 7D cannon, but im just having a little trouble downloading videos to youtube, is there anything special i need to do. I dont mind waiting a whole day for my videos to download, my problem is that it always stops downloading for some reason, any tips of what you think im doing wrong? Please please respond...

  • That was ABSOLUTELY PERFECT. Thank you. I had to search many tutorials and still none had all the information that i needed like this one does. Superb.

  • -I do admit that larger image sensor makes it easier to achieve shallow DOF, but the sensor doesn't actually cause that- Okay, if the sensor isn't causing this, what is?? To say sensor size has nothing to do with achieving a specific DOF is just plain wrong. Especially when you're using specific lenses.

  • goooood tutorial, we want MORE MORE MORE MORE MORE MOREEEEEEEE )))

  • I'm a little confused-- I use my 50mm (shorter focal length than recommended) at 1.8 to get the nice bokeh on my T2i....

  • @amanwithnohands 50mm f1.8 lens is a real nice lens if you want to get shallow dof. If you watch the video again you'll see that I don't "recommend" any lens. All I'm saying is that the longer the focal length the more shallow the dof. If you were to shoot the same scene on your t2i with the 50mm and then the same scene but with a larger lens like a 100mm at the same fstop and distance to subject then you'll see the DOF will be even more shallow. But for u 50mm might be shallow enough.

  • If you had put a lens shorter by 1.6 on the 7D (about 30mm), instead of moving the 7D further away from the subject, you would have achieved the same framing (magnification) as the 5D, keeping the same perspective, but the depth of filed on the 5D would be 1.6 times smaller, thus - a bigger sensor has a smaller DOF. Excellent tutorial anyway, I've seen some of the others - you are really good at what you do!

  • @degigi2003 Thnx! Glad you enjoyed it. Also, what you jut mentioned proofs exactly what I said in the tutorial, that the DOF is not affected by sensor size but by 1)Aperture 2)Focal Length 3) Distance. By putting a shorter lens on the 7D by 1.6 times, you're in fact changing the focal length, which affects the DOF. I do admit that larger image sensor makes it easier to achieve shallow DOF, but the sensor doesn't actually cause that.

  • Comment removed

  • Thanks for clarifying the image sensor size giving less depth of field confusion.

  • Excelent tutorial! Polcan, you're my Guru of filming using DSLR :). I'm wainting for more!

  • I'm guessing that the 1 dislike on this vid is due to the 14 min length. Shorter vids will engage more viewers.

  • I'm sure this'll sound like a stupid question to you... , but why do cameras made specifically for video perform much better then DSLRs when it comes to video. What is the major difference in the hardware?

  • @Fred, that makes sense, I guess I should say sensor size on say a 5D mark II will have a different DOF at say f4 than will a 7D with the same lens at that same f4 stop. And if that's particular lens is wide open at f4 and nit creating the DOF wanted on a 1.6 crop sensor, than yes, sensor size does play a factor.

  • happy new year tom, great tutorial once again! very detailed and informative. kudos!

  • Negative, sensor size does indeed have a direct effect on DOF.

  • @tubularsensation Not really, all it does is change the field of view (FOV), meaning that a 25mm on a 35mm camera will correlate (roughly) to a 12mm lens on a 16mm camera, the bigger the sensor, the wider the FOV, the longer the focal length required, the smaller the DOF

    There is a simple rule, the crop factor is equal to the number of stops of extra DOF a smaller sensor will have, 16mm-35mm is a 2.5x crop factor, so f2.8 on the lens = f 5.6 on the DOF chart.

    Fred

  • Very well explained. Thanks for the tute.

  • With a smaller sensor the focal length of the lens must be shorter to give an equivalent field of view for a given subject distance. This is what makes the depth of field larger for a smaller sensor.

  • Hey! I don't know if people count this as "spam" but I'm planning on setting up a channel of my short films here on YouTube using my canon HDSLR. If you have a spare 5 mins, please come and watch my film and feedback would be fantastic! I'm only 15 and want to make films, so thanks very much! ;)

  • Confusing? These are easily the most informative tutorials I've seen on youtube. It's nice to see stuff that is so detailed and informative without coming out as glorified product placement.

  • This was a much needed tutorial, most tutorials do not go as detailed, usually they mask out somethings and suggest you buy something. thank you..

  • video on camera movement

  • thanks again! fantastic tutorial!

  • I had a great day and caught some graphic footage ... so graphic I was not sure how to present it ... can you take a look at what I came up with and "suggest" ???

  • I have known of f stop, depth of field, shutter speed aperture trade offs ... what I did not know was the smooth effect a slower shutter speed had on motion ..as in a faster shutter speed gave the strobe effect ... also I was not so famaliar with the ND filter ..very nice to have a variable filter to just adjust the light ... I say these things to let you know a little about your audience ... controlling the amount of avaliable Light

  • @ricmcmiliion Absolutely. Those were the new things that I learned, too. Now I know the use case for an ND filter.

  • u guys looked freakin freezing!!!!

  • @RoathRipper Yup...won't lie... this was not the best day to do such demonstrations outside. At one point we had to stop and go inside cuz I couldnt move my fingers.

  • Brilliant tutorial! Thanks for this.

  • plz do a video on the hv40

  • @cashimirs that would help me too lol..

  • you are very helpful

  • Comment removed

  • Excellent! Probably one of the best explanation and examples of dept of field. Also even though I thought the sensor effected dept of field how you explained that it doesn't makes sense. Thanks

  • @tvend2 two shots, shot at the same distance, at the same settings, on two different size sensors, produces identical depth of field. The only visible difference is the smaller sensor will look cropped. To get the same framing with the smaller sensor, you need to physically move the camera backwards, thus altering your depth of field, giving the larger sensor the advantage of being able to get close to the subject while maintaining a wide angle. hope that helps!

  • ooo man i'm pump up for the next tutorial - polcan you gotta also give info where you get the gun props for that scene.

  • Thanks! Keep these tutorials coming!

  • By the way, it was really helpful! Thanks! :)
