Aperture

[lastseries2011]

Coincidentally im using earphone to watch this. :)

[kamihakai]

Hi, I know apertures control light entrance and depth of field, but, I want to know How the light rays enters through the lenses, are they in cone shape, and if so, I would think (but it's not true), that decreasing the aperture, would remove some light rays coming into the sensor, thus reducing the quantity of informarion at the border of the image... how does it works??

[MichaelTheMentor]

@kamihakai Its an excellent question, I should probably make a video about it. While total amount of light is indeed decreased, the coverage of the media is the same. (And yes it is cone shaped). Wider apertures allow for more light to enter the lens, but the coverage of the media is the same.

How come i'll always turn deaf when i watch this video

[jellywillreturn]

This was a triumph! I mean... thanks for the camera tips.

[kalzorath]

[tinareddy46]

struggling to hear you!!! turn the volume up!!

[airbendingavatar1]

@gavlemab Portal nerd and proud of it! :D

[airbendingavatar1]

Whenever I hear "Aperture" I think "Aperture Science"!

[gavlemab]

@airbendingavatar1 :D portal nerd :D

[4at4ish]

now your thinking with portals

[Arzenimus]

omg it's like this guy is trying to sound as quiet as he can. i don't want to sound rude, i mean it is a helpful video, but it really annoys..

[rowdyman22]

@ 2:30 how do you figure out those numbers?

[MythicSolider989]

I thought this had something to do with Portal 2

[ourlighthouse9]

very nicely done.......thanks

[starlightaoril19]

hey everyone! see what u think of my photography please im having trouble getting people to see my work,so go to my channel and click the photography video and tell me what u think.thanks!

[mackenzie2881]

I recently bought a fully manual camera as I was totally fed up with my Sony point and shoot. However using the supplied manual was tedious and confusing. I stumbled across your tutorials and have to say that they are brilliant. Your explanations are crystal clear and very easy to follow. While I watch I play around with the camera and have become really confident adjusting different settings. My photos have become much better and I never use auto anymore.

[avcrk]

Finally ! At last I understand depth of focus. Thankyou.

The wall of focus makes it easy for me to remember.



[tomislavhecimovic]

Did I got something wrong or did you?

Please check @ 2:17 I thought that aperture equals focal lenght divided with diameter of entrance size, not the iris diameter.

[MichaelTheMentor]

@tomislavhecimovic It is the opening that allows light in depending on what type of equipment you are using, if it was the diameter of the lens entrance, aperture would never change.

[MichaelTheMentor]

Have you updated the firmware? If you are in Manual Exposure, this should not be happening. Also, check your ISO that it is not on "auto".

[coolestspott69]

in 550d, movie mode, manual exposure, and MANUAL focus after hitting the rec botton when i zoom in and out the exposure and shutter speed varies therefore making my shot shot going brighter and darker, tried hitting the lock button * before rec, but doesn seem to do the job,am i doing this the correct way inorder to lock my exposure???pls help!!!

[FirebrandNIRE]

Excellent presentation!! the only prob I had was the volume was really low :/

Thanks!!

[TheTigidig14]

thank you!!!

[nyzwerewolf]

Great video but it is very hard to hear you Michael. My Macbook Pro's volume is at MAX and so is the Youtube player...

[DDRandDSLover]

Wow, this was VERY helpful. All your videos are helpful! Thank you!

[gigiboxa]

hy guyz,i heard a theory which says: if you have an elevated number of F (ex f 32) you can have your pictures not as clearly as you ca get with an medim F number(ex. f 11). is that true or false? please reply to my comment! thanks!

[PhotographersOnUTube]

@gigiboxa It all depends on the lens. Sometimes the picture doesn't come out very clean if it's wide open or small opening. I have never gone over f/18 and lower than f2.8 on a macro and f/1.8 on a prime lens.

[LadyPrankers]

This had helped thank you :-)

[mekanda100]

Great video tutorial, thanks!

[MrZachPower]

[russellrehman]

This is the best explanation of Aperture I`ve seen on youtube so far. Thanks dude !!

[cheryl1358]

I"m kinda slow..and this helped thanks...lol ;O)

[pickurstyle]

Thanks for this tutorial. I was a victim of thinking the smaller the f# the smaller the aperture. Thanks for clearing this up!

[iamknocking]

Wonderful

[kneedrag32]

This is the best explanation of Aperture I've seen on youtube so far. Great job!

[homelessballoon]

Very well explained and done!

[Ph0xF0rce]

this video cleared alot of of questions. and helped me understand f-stops

:}

yay

[fdxfield]

I love his voice. It's so easy to listen to, thus creating it easier to comprehend. And the fact that his examples and visual aids are perfect!

[photogirl317]

Great video. Ready for more.

[jayjaySTAR718]

This video really helped. thank you.

[c4lmn]

Man your good im going to pass my photography test now you and the depth of field thats amazing :) thanks man!

[nil1230]

nice. i learned something..

[Hilton205]

5d mark 2 FTW !!

[JohnPersonage]

Great video Mike... but I think you need to turn the volume up. I'm on max here and struggling to hear you.

[eriqcxyzloogue]

i am planning to buy a dslr and i am choosing to buy a canon 50d or a nikon d90. help please? im so confuse. thanks.

[jaysucks312]

i have a 50d

im a canon person though.

great camera if you have the money..

[LluviaDeHachas89]

If you google: nikon d90 vs canon 50d, you'll find lots of comparisons and reviews. Both, canon and nikon are leaders in sales and quality, it's up to you: be a nikonian or be a canonian.

[ermollejuo]

Hope this help, but I've been looking for the one that has the biggest image sensor which in your case the nikon has the biggest one

[Filoz]

D90 of course eriq, if you have the cash, if not, aimfor d60 or d80.

[lbomb8]

I prefer Nikon's but each to their own.

[nyzwerewolf]

thank you! great tut!

[MichaelTheMentor]

Ill have a DVD coming out on this in about 3-4 weeks. Best wishes! M

[veraso1]

Thank you for this video.

[atlas9online]

[lordarathres]

Finally someone who knows his stuff. It makes sense now how f stop and apeture are RELATED with DOF. Nobody covers this. thanks man.

[0mrme0]

[daveawebber]

yes can u increase volume i have headphones on and can just about hear

but great vid keep em coming (louder of course) lol

[mafiasyndicate]

Excellent... I was very confused until i watched this video....

[howlobb]

Please make the volume of this video louder please. I could barely hear it. Other than that it was very good.

[ourvinylcollection]

heh. i had to learn all of this just by shooting hundreds of rolls of film.

[5Whiskers]

Thanks a million for these vids! I can finally take my photography to the next level. =3

[Dunpeal875]

Amazing!!!!! REALLY THANKS!!!!!! Great Videos!!!

[FloridaKevin]

Excellent video tutorial on apertures and their effects. This is my first video of yours that I've viewed. I'll be sending links to friends to this to help friends and family understand how to use their cameras.

Good work!

[tasulinha2]

sorry, where do i find the f 2.8 in canon 20D serie?

Thanks a lot and thanks for the videos.

[shanesoc]

thanks for the video it was great , but could you try and get them a bit louder. thanks

[manova1]

My camera is arriving tomorrow, I'm excited to see all your videos. Awesome!!

[GhostFight3r]

If you liked this one I found an even better explained video about depth of field, watch this one: watch?v=BfOC_Msb1dI

It really helped me

[karonxls]

I could kiss you ... THANK YOU ... your are the first teacher that I can relate to ... I have had such a hard time understanding depth of field for quit some time, the ruler is genius. Simply Michael you are an outstanding teacher and I can learn from you.. Thank you so much

[cstishenko]

Thank-you. You've made it incredibly easy to understand and put into use.

[marcdecious]

NOW I EFFING GET IT! your visual were critical to my dumb brain understanding...

[12thDecember]

Excellent tutorial, Michael. I especially liked the demonstration of DOF using the ruler. That type of imagery really makes the point.

[colossusbeam]

awesome video, thx much

[quadruplelatte]

Finally a good video on aperture - just wasted about 30 minutes getting nowhere. I can't wait to check out all your videos. Thanks!

[Str1k3rrr]

Great video!

[hollycardinal]

This is great!the videos are so wonderful!now i have been watching them and reading my manuals.There is one thing i am having problems with!i can take great photos at night yet i can not seem to get pictures at night of fireworks or pumpkins lit up it always is bright!!what about taking pictures of the stars?

[MichaelTheMentor]

You tell me...how would you get more light into your camera?

[amira4princess]

Thanks Michael, that was VERY well explained!

I will recommend your video lesson to every Photography enthusiast i Know

[OzJarrodh]

Now, where were you when I did photography in Yr 10!?!? Ok, that was a long time ago, and maybe I've forgotten a lot, but that was a very well done video.

Thanks.

[shownine]

the best mentor and educator i found in the entire you tube for digital photography.thenks a lot micheal..!!

[migofilm]

Thanks a lot man. Really helped me out!

[maiamie0305]

Thank you so much for this great lesson. I've just bought canon 40D and have no clue about the camera. I've no idea about apertures and f stop.

I have questions tho, when I buying a camera lens, should I only buy the kind that have image stabilizer?

I need lens that can take wide angle in close area and I need telephoto lens to take picture of flower or butter fly.

Thank you for any suggestion would greatly appreciated.

[MichaelTheMentor]

I highly suggest Canon 40D Crash course by Michael Andrew. (That would be me ;) ) if you click on the link to my blog you will be able to order it. It covers everything a beginner would need to know about photography, lenses and the Canon 40D. Trust me, it is an awesome DVD. :)

[ehtep]

Hi, I need a answer, When I look through a magnifying glass it turns the image up side down, When I look through a really tiny hole it for some unexplainable reason turns the image upside down too...Why is this???

[ehtep]

Our eyes have a lens to pull focus, Cameras have lenses to pull focus, BUT how on earth can image be pulled into focus with out a lens, like a pin hole camera or the Moken people who pull visual focus under water by constricting their Iris??? Hypothetically can a camera with a ISO of 2 million be made which solely pulls focus and magnification through a set of Apertures only???

[Hybrid93Hatch]

Very helpful video!!  Thanks for posting!!

[Flianz]

This is very helpful, thank u very much. And the voice... Why my school teachers didn't have such a voice?

[theehill]

this is the first time all of the aperture stuff has actually made sense. thank you so much.

[placebowithmeds]

this is handyfreakingdandy.

and yes! the smaller the aperture the higher the number, totally backwards :P i'll check out the rest, thanks :)

[Emixsan]

Very nice explanation. Not to mention you have the perfect voice for this sort of thing.

Thanks very much for these videos...they help.

Hi Sem...It depends on what you are trying to do. For Portraits I like wide apertures. :)
