ISO shooting?

I wouldnt go auto even if I could :)
 
For walkabout I use Auto but I set it to increase only if the shutter speed is too slow for handheld.
 
if iso is on auto then everyhting else may as well be on auto as the results will be the same.. ie unusable pictures becauee the camera got the exposure wrong... and that does happen a lot in adverse conditions with varying light.

Not always. I use my D700 in auto ISO sometimes. It only raises the ISO if it needs to, and you set the slowest shutter speed before it raises it, and the maximum it goes go.
For instance I have mine set to ISO 3200, but only if the shutter falls below 1/50. Ill change it depending on what lens Im using, so the shutter is always faster or the sameas as the length of the lens.

My pictures are perfectly useable using this set up.
 
Well I suppose then in comes down to what you're shooting. If you have time to do it all manual then that's the best thing to do. If you have changing light and need to get quick pics then use auto as much as you need to.
 
Manual. Every setting you switch to auto is one less parameter in the end result you have control over. Give the camera one parameter to vary at most (Av or Tv) and take control of the rest.

Auto-ISO doesn't use the full available range on the 40D, but this may have been improved for the 50D?
 
whats with all this macho manual stuff? modern cameras know exactly what they're doing 95% of the time. I often shoot on manual but with auto ISO - means I get the aperture and the shutter speed I want every shot.
 
I do not use auto iso on my 50d as it often picks intermediate values (eg. Iso 250). These intermediate values are artificial in a sense as what the 50d is to actually pick a full ISO setting, say 200 if it actually wants to set to 250, and then it brightens the pixels to simulate ISO 250. Not only can this increase noise but if the camera is going to that I would rather control the image myself and adjust either the shutter or aperture to get more light on to the sensor. If the intermediate iso settings were implemented properly I would use it a lot more - its nowt to do with macho. If I want to be macho i undo some shirt buttons and put on a big gold medallion and a stick on handlebar moustache. I got my understanding of auto iso from tdodd in the big 50d owners thread. I hope i have not misquoted him.
 
I use manual on mine - but Nikon d have pretty sophisticated auto iso in that you can specify only when it will raise it, ad whether it'll o over a certain value, so say it will never go high than 1600. I know canons have pretty rubbish auto iso, it's generally around 400 and that's it. They might have improved since I last had one, I don't know....

manual here, but for me its more about learning at the moment, once i got a basic undersatanding of how the camera worked, i stuck it on manual and its not been off since, its forced me to use it properly and think about how to take a shot every time i use it, which i think has helped me learn what i'm doing... maybe...
 
Auto ISO works fine for me, set your highest acceptable ISO, and prefered shutter speed, and the AutoISO does a pretty good job.

Most of the shots I take aren't "serious" though, if I was doing serious stuff I probably control it myself (but not always).

Same for me.

Auto ISO on a Nikon works differently to the Canon system, or it used to.

I have my D300 / D700 set to Auto ISO, and control the shutter speed and aperture manually.

I can see what is happening in the viewfinder window, and will tweak my shutter speed or aperture to suit, all without taking my eye from the viewfinder.
 
auto iso on P with my nikons. min shutter speed, only increases iso when it needs to, perfect for most of my shooting which is show jumping - often in poor light. just setting the camera to do what any decent photographer would do anyway.

I heard the P mode is pretty good on Nikons. I guess that is why awp only uses Nkon. :) /runs for the hills.
 
I never use P mode though !

what does the 'P' stand for anyway? Practice Mode? Play Mode? :D
 
oh.. i forgot to say... i'm rock hard, so i always use manual. :thumbs:
 
Nah it's P off - I know exactly what I'm doing :)
 
For me it stands for panic button, as in you don't have time to faff, a great shot has just presented itself, do something fast. It has it's uses!
 
Manual ISO, when shooting landscapes in daytime AND in failing light & night photography have it on it's lowest setting always when on a tripod.
 
I use auto every now and then, the auto ISO on the D700 is pretty good, spot on every time, like its been said I set the highest iso I want it to go to and lowest shutter speed and away it goes. and P I believe is program...
