Great video, Mark. Thank you.

[FIREHAWK1979]

I'm using a Canon Powershot SX30 IS with a frame rate of 1.3 frames/second for continuous shooting, this is a bit slow to catch the moment. Would I get comparable results shooting video at 30fps and capturing a frame on the computer?

[LAtrailers]

Fantastic video, Mark... Thanks!!!

[denmar1998]

Hey Mark, Thank you!!! Now I finally know what to do with that selector switch on the side of my lens. I go to dog trials where I shoot dogs running 35mph+ and I was always told to turn off IS but I never did but used it on 1 instead of 2. Thank you ever so much!

nice 1 mark, cool channel very very helpful

[jsalting]

Mark, how about sport photography indoors, do I have to follow same rule

[SG3089]

Lol Biggest Fan

[shlomki]

hey mark, about the rule of thumb you talked about at 5:04 . is that rule true for all lenses? i have the Canon 17-55 F2.8 IS USM, the F2.8 is constant throughout the focal length, so when i zoom in, my aperture doesn't change. does this rule still apply to my lens?

thanks. :)

[playerito2009]

@shlomki the rule is for all lenses but to shoot handheld at least the shutter speed have to 1/60th of a second!!! and to freeze motion it has to be faster than 1 /125th...it depends what kind of move you want to freeze!!!

[shlomki]

@playerito2009 thanks for the explanation!

[toshiroo]

@shlomki

and it depends on your sensor, the rule is correct is u have a full frame sensor 24x36

meaning example a 50mm would be 1/50s to avoid blurry ( caused by shaking , not to freeze motion)

but if u have a APS-c sensor, u need to know the crop factor, example for canon 550d : x1,6

so for 50mm, the shutter speed minimal would be 1/ (50 x 1.6) = 1/80s

Im a total rookie with my new t2i but I tried the settings 1/1600 and AI servo and my shots are all too dark. I even adjusted my ISO all the way to 6400 just to make the shots light enough to view. must be doing something wrong. It is extremely overcast here though I am using tele 55-250 is. Can this only work on bright sunny days. my f-stop at 4.0

[VirginiaBand]

@yes350yes hey, when pictures are too dark there are 3 main reasons:

A) shutter speed is too fast

B) aperture opening is too low

C) ISO too low

Since your IS0 is high, and your aperture opening is also wide, that means there is something wrong with your shutter speed. 1/1600 was way too fast for the light you had. If you were using the rule of thumb, you would have been using a maximum of 1/250 (but if you add crop factor(1.6) it becomes 1/400) considering a full zoom(250).

[urbanlion100]

@VirginiaBand Low ISO darker pictures???? ISO amplifies the light the only boost of light is not actualy light, is noise. Make sure u copy and paste it properly next time.

[VirginiaBand]

@urbanlion100 Don't get me wrong. You were right about the "noise" part, but it can be noticeable just at a "very" professional level or at ISO's higher than 800-1600 or in very dark situations. If you are not a professional, for sure you would increase the ISO from 400 to 800 for the sake of one shot, rather than losing the content of the photo. A higher ISO of the camera works better (in this case) than in postproduction when one tries to increase the brightness of the same picture @lower ISO

[jonakagwapito]

hi mark i just want to ask about canon 1000d does it has a continuous drive mode...? thanks...

[ashrraine25]

hi sir mark..i just wanna ask where i can find the continuous drive mode in nikon d50?

[ljsphotos]

Hey Mark, love your tutorials! I have a question on focus. I am getting older and my eyes are not as sharp. Sometimes my images are slightly out of focus at post production, but looked ok when I was taking them? Is it corrective eyeware that is necessary, or will a diapter setting work at all levels and what is the best way to secure foucs related issues. I mainly use the center focusing method on still subjects and single mode focusing with my 7D. Thanks. Lyndon Johnson.

[endrumsenthil]

Actually i have a doubt. In the Episode 13, for taking sports related photos, u told to keep the shutter speed slow. but in this episode ur taking photos with large shutter speed. why this difference?

"My biggest fan" haha!

[bigdfevrier]

@Claggy That fan has to be one of the best fans in the industryl You actually detach the legs and it becomes a hand fan.

[DantePasquale]

Mark, does the rule of thumb rule work for cameras that aren't full frame like my XTi? I usually use 2x the length, but was curious if I can go slower if I need to when shooting hand held. For example with 200mm zoom I don't shoot slower than 1/400

[snapfactory]

@DantePasquale The rule of thumb still works. But I'd do some tests. I usually compensate more for longer lenses. I'm normally shooting around 1/500 when shooting a 200mm lens. So I think you're right on target with the speeds you're already using. An IS lens will allow you to shoot slower and a tripod will let you shoot much, much slower (of course). :)

[Josheeboy]

My nikon d5000 doesn't have a continuous focus button on the side like that. Is it somewhere in the setting where I can fix it?

[1Sniper101]

@Josheeboy its in the settings menu..press the "i" button then goto AF settings and select AF-C
