Are you shooting RAW and how long have you had your D200?

RAW, so I can make some adjustments, I git the camera second hand and I think it's a bout 4 years old

what metering mode are you using. can you post a sample.

Usually centre spot metering ... looking back at some of the images, I can see that I may have had the shutter speed too low too
 
I have a D200, had it for some while. I won`t sell it because for certain subjects it is a brilliant camera. However, I do find that more PP is needed with that model than my 300 or 700, RAW files seem very flat but with a bit of work ,come out beautifully.

I tend to use it at ISO 400 or less, maybe i`m wrong I dunno, but anymore than 400 makes it less pleasant to me.

For the record, I took my best ever wild peregrine shot with a D200 and a 80-200 lens, so it can perform if in the right, or lucky ,hands.............:thumbs:
 
Never really considered auto ISO, as I just prefer knowing exactly where my starting point for exposures is.

However, used it today in manual and it had its uses when using the long lens to retain a shutter speed and aperture on the long lens, although exposure comp is now handled by the exp. comp button rather than one of the command dials.... not as easy IMO.

The other concern is when batch processing the NR.... Obviously you have to sort the images by ISO

I have tried it but got caught out when it went to 3200 and I did not notice
I now realise that it is possible to set an upper limit on the 550D
My friend ran the shot through lightrooms noise reduction and it turned out OK:)
I mainly use AV mode and havent used auto ISO since just set it to 400 or 800
 
Strange that the majority who have posted seem to be saying Auto but that is only 8% in the poll while 'I choose the ISO' is coming in at 63%. Must be loads taking the poll but not bothering to post.

Mine is usually set on Auto.
 
Mine gets left on auto most of the time unless I've got time to play around with it.
Still learning though...
 
Auto ISO for me. I generally set the max depending on the lighting and then away we go. It gives me more time to capture the action as opposed to looking at the histogram / playback every few minutes
 
Manual setting most of the time but when the situation is fluid and the light is variable, I'll switch to Auto ISO. :)
 
I try to set ISO for every shoot keeping down to 100 if possible. Auto is fine however with reasonable light and when you have distractions or too much to drink.
 
I try to use auto ISO and set the minimum shutter speed at night as not to miss any shots.
 
I always choose the ISO. Unlike Neil, I use manual settings for sport like rugby/football. I used to use AV but once I gain experience and took note of the pros on here, I set a minimum SS, a suitable aperture, and an ISO to suit. As the light fades, its a balance between upping ISO and lowering SS or opening aperture.

When I've experimented with Auto ISO I find it unreliable. In bright sunlight when you'd think it would be as low as it goes (100) its often 400, and in dim light it doesn't go higher than 800.
 
I tend to use manual ISO if I have the time to sit and adjust it while taking pics. But for walking about and variable conditions I tend to stick it on auto mode. Not tried it yet with my D300 but from what others have said in this post it seems quite easy to set up and use.
 
When you use auto iso in Manual you are giving your camera control of the exposure just like in Av or Tv mode.. they may as well call it iso mode.. Your no longer in full control of the exposure...

In situations where light changes faster than you can reset your camera then you need the camera to take over the exposure..I am not a Manual pureist :) But out of the three possble semi auto modes (av, tv and auto iso) i agree wiht a couple of others above that auto iso is the least reliable for getting the exposure right and is sometimes over exposing..

However there are situations where I have no option but to use auto iso when av or tv wont do the job... So like anyhting elseo n my camera.. auto iso does have its place.. But I wouldnt ALWAYS have any particular setting..
 
auto iso on my nikon gear and my pentax gear was 99% spot on, the pentax underexposed slighlty when it went wrong and the nikon over exposes slightly, but the only time i use manual as i said befor is in the studio(consistant lighting) and flash in general,, so manual on the nikon is great, ok auto iso is involved but i can set my shutter and apature and if needs be over ride the iso by using ec.

The 50D is basically pants at auto ISO ... I use mine in fully manual but with other makes (my K-5 for instance) it is much much better and I am quite happy to use it.

Pentax have a setting on the selection wheel for auto ISO .. it is called TAv mode.
 
Ive tried auto ISO on my 450D in all the modes i use and found it utterly useless.

Av/Tv mode it seems to be stuck on ISO400 regardless of whether its dark indoors (and therefore selects a shutter speed too slow to hand) or outside in bright midday desert sunlight (so silly high shutter speeds). It very very rarely changes. It doesnt seem to change at all on manual exposure mode.

So for me, no - i don't use it!
 
I set it manually on my D90. There's a handy option in the custom menu called something like "easy ISO". With it on, shooting in aperture priority one wheel does the aperture and the other does the iso. In shutter it's the same, one does shutter speed the other does iso.

I shoot 90% of the time in aperture. So I set my aperture and then adjust the iso as low as I can get it whilst maintaining a useable shutter speed. All of this is without taking my eye away from the viewfinder, as while I'm changing the iso I can see what shutter the camera's meter is picking for me. Seems to work well for me.

When I first got the camera I tried it on auto but it seemed very eager to up the iso rather than just slow the shutter slightly, so I sacked it off and haven't used it since. Maybe I had it set wrong I dunno. Will give it another look tonight I think.
 
Having a D3s, i would be stupid not to take full advantage of the auto ISO. If shooting landscapes or any tripod work, yes i choose my ISO which is nearly always at 200. But hand held, always auto :thumbs:
