Advanced Tips for Canon EOS 40D : Canon EOS 40D: Manual Exposure

[JClavinPhotography]

Guys, you should NEVER use aperture to control light. Aperture is your creative control over depth of field! ..in this video he changed from F/2 to F/7.1, effectively he would be taking a different photograph, the DOF would be so altered. Set your aperture for the DOF you want. Set your shutter speed for a good exposure and leave your ISO at 100, not 400 as he showed. If your shutter speed slows too much so you are beginning to have camera shake, then start increasing ISO, thats what ISO is for!

@JClavinPhotography Ok Mr pro, you forgot to say about needing a faster shutter speed as you go to F 2 in the first place because the DOF is so shallow your focus is off if you or your subject so much as takes a breath. Shutter speed is hell of alot more vital than your assesment.

[JClavinPhotography]

@SuperMangn Your answer doesnt bear any relation to the point I made. ..none at all, and to suggest that a faster shutter speed is desireable with wider apertures so that you or your subject dont wander out of DOF is ridiculous. Its the time between focus lock and shoot that needs keeping to a minimum, not the tiny instance that your shutter is open. You are right that correct shutter speed is vital (subject, situation, camera shake etc) but not so you can better handle shallow DOF.

[SuperMangn]

@JClavinPhotography At 1.4, 1.8 or 2.0 aperture they dont need to wander out of fucus, a tiny movement either from you or the subject will ruin the picture if your shutter speed is not fast enough and thats a fact.

Does it work for the 20D also?

[bham184]

He probably has a fixed length lens. They can have real wide apertures

[johangunnarsson1]

No, I dont think so?

[johangunnarsson1]

Great video. But I am confused about one thing. It seems you have something like a 17-40 or 16-35 lens on? How is it possible for you to be able to chose a 1.8-2.0 aparture when these lenses cant handle those low numbers? Just curious..!

[mail2kvasanthkumar]

lower aperture can be obtained with different lens, you will not get such a lower aperture on the normal lens

[HankJMH]

Another nice video. I think you should have told even (especially) beginners at using manual mode that they cannot rely on the camera's exposure readings in different kinds of lighting situations. The camera is using reflective metering and assuming that the portion of the picture you're taking is about 18% gray. Good explanations and demonstrations.

[homersimpson587]

lol if you dont know about manual mode you shouldnt even have a 40d in the first place...

[lillen300]

well i have only used my mobile phone for taking pictures and sometimes if i try they turn out great and i really want to get this one :)

[rvenes]

I've switched to P to M becouse of this video... (and it worked fine), but will go back to P when needed.

[p3p3nietnagel]

I think one can assume, that everybody who owns a 40d knows that stuff.

[lewisw92]

Actually, because the exposure meter is blinking, it means it is either more than (+2) or less than (-2), i.e. off the scale.

thanks for the lesson

[GuiselaBarrios]

I love your teaching, and really appreciate the time you take for other to learn

[Aphesia]

Give the guy a break. Hes teaching folks how to become familiar with the features of Manual mode. This may be advanced to users who are starting out or come from an "Auto Mode" background. Im sure this will be beneficial to someone.

to get your quick dial to work, you need to turn the on/off button to that slanted line above the "on" function. if you don't the quick dial will not work. it's in the manual. photography is a balance of shutter speed and aperture and what you want to acheive is to have the exposre reading right in the middle, most of the time if you're a beginner. So when you press the shutter half-way down look to see where the line is and move the speed or aperture up or down so the line is in the middle.

[skillbill83]

Thanks man. I had a bit of trouble with that issue and now i get it.

[ashkiashkiashki]

hi I press the shuter bottom half way and rotat the quick dial but it doesnt work, is it depend that what the lens is?

[monobansomniac]

you don't have to press the shutter button half way. It doesn't depend on what lens you have.

[maxbarros]

come on... advanced???

whats the tip? if its advanced please start from where we know how to use the camera

k thx bye

[chnzshyguy]

seriously? advanced tips? rotate the dial to the left to get from AP to manual? give me a break... where can i find some REAL advance tips??

[GLENIANO]

you are a great teacher!
