The age of Auto ISO ?

I archive my wifes pictures and have noticed that she is really getting some great clean and clear pictures. She uses auto ISO on her camera, I use what I feel is needed.. I have taken some with it and find that it works OK for most outdoor shooting. Have we crossed into an age where auto ISO is the way to go ? I think so.

I find auto ISO tends to err on the high side, the lower you can get away with the better the pic;I avoid it totally!

Re: The age of Auto ISO ?

Not used Auto ISO and think that noise is still sufficient of a problem that I won't for the time being. Never say never though!

Again, always find it sets the ISO way higher than I would want so never use it.

Re: The age of Auto ISO ?

Auto ISO can be useful as long as you can control the auto range. If it goes to 800 or 1600 then it could obviously create problems. If you can set it to go to a maximum of 400, I think it can be a useful feature. Like all auto features though it's dangerous to rely on it entirely. Sometimes you need to take control and override.

Re: The age of Auto ISO ?

We use auto ISO on our compact cameras in good lighting they work fine often going to 50 ISO but if the lighting is not so good then it goes very high, sometimes when shooting family type snaps in pubs and clubs it can shoot through the roof as to speak, however on our DSLRs we set the ISO mainly to 200 for outside use when the lighting is good, 400 ISO when its cloudy, 800 when its really dull and higher when its impossible. We have no problems with these settings!

Re: The age of Auto ISO ?

I use auto ISO on my shooting bank which is set up for action shooting. I can get carried away in getting the shot so it is handy that the camera will bump it up if the settings I'm using would normally underexpose.

I don't shoot much action stuff so it is a bit of a safety net for me.

Don't think my D300s has an auto setting.

I use manual anyway!

Unless they have changed it, I think you'll find it in the shooting menu.

Re: The age of Auto ISO ?

I use it a lot on my DSLRs but not often on a compact. As Dabhand said if you are in a hurry it's nice to know in fading light it will keep shutter speeds up automatically. You can control most of the parameters so it stays at the lowest level you have set until it needs to raise it to maintain your pre set minimum shutter speed or to cope with what you have input as shutter speed on shutter priority or manual.
Also if you want complete creative control if you set the camera to manual but have Auto ISO then you can set whatever combination of shutter speed and Aperture you want and the ISO will change to take care of the exposure.
In some ways this is better than doing it manually because it has smaller increments than can be entered manually.

Re: The age of Auto ISO ?

Never had auto ISO on an SLR, my 20D was pretty straight up and good around 100-400.. ISO My newer camera will give 1/3 increments and I have noted that 125 160 and 640 or 1000 show up when shooting in lower light. Also the noise seems to show up because I have set the ISO manually and will stay cleaner with the auto setting. My detail seems to be better when it makes little ISO adjustments. I leave my lumunation priority settings and etc. off. Anyhay, sounds like it is one of those things that is slow to catch on and the newer cameras are doing a better job then most think. Would like to hear from more who have had some experienses with this.

Thats a very valid point,but I find that auto usually defaults to the highest level that has been selected which in many situations is still higher than the light levels really require.
Like everything else its all down to personal preference but when I'm out and about I try to assess the situation and set the iso at an appropriate level before venturing out.Some cameras are better than others at high iso,some have problems at 800 + . I got rid of my G9 because anything over 100 was rubbish,I've now got the G11 as my take anywhere and I have to say its a vast improvement;its a bit bulky but still highly transportable.

Re: The age of Auto ISO ?

I understand that the camera will read what lens is on and focal length. Then sets a default for the shutter speed. Meaning that it will shoot faster but not slower at that default speed for that lens. I have been lead to beleave that this is a smart piece of the firmwear that is getting better and better quickly. People don't like noise and that's what makes me think that it hasn't been concidered as one of the major changes to come along. I am likeing the changes I see in my camera and wil watch this progress with interest with the next generation of cameras.

Re: The age of Auto ISO ?

I had not even thought about Auto ISO but the original post prompted me to check whether my 5D2 has auto ISO and it does. It is not something that I plan to use as I do like to be in control. For most of my photography, I have sufficient time to set the camera as I want it so would not trust it to choose the right settings for me. However, I would not say I would never use it (I recall saying I would never use auto focus about 25 years ago but I do often do so), but might consider in the circumstances where there is insufficient time to set the camera and need to grab shots with quality not the most critical factor.

Despite being a camera control freak, I do normally leave my camera in Programme mode so, if had have to grab a quick shot with no warning, there is a reasonable chance of capturing a shot. Anyway, it is good to hear that auto-ISO is effective.

Re: The age of Auto ISO ?

Fuji's EXR system has gone a long way to address the problem.I,ve tried the F70 exr and the S200 exr and I have to say the results are impressive.In SP mode pro low light the camera takes 4 shots ,usually at 1600 iso,stitches them together,all at hand held,and the results really are very good indeed, albeit at half maximum reolution; when the ambient light is low this really is a very good alternative to using a tripod or flash!
In high iso low noise mode or D-range mode the results are equally impressive bearing in mind that these are small sensor cameras. The downside is half max resolution but I think in the appropriate situation the resuling picture quality is worth it; unless of course you require poster size prints.

Or mine.

I use it, I let it go to 3200 and occasionally 6400 if I need to. It's no big deal noisewise, unless blowing up to silly proportions. There are times when you don't want to use it mind, just remember whether it's on or not!

You stand like a rock simpbow,,, That's funny. I just felt like I was having a little peer pressure from the wife and all of her auto settings were pulling in some great detail and she shoots Jpeg. I maybe have popped off about 100 pictures using auto iso and I have a feeling as I did when I would use metering of a different mode before I went to manual. I have found that my colors seem to look better with the subtle iso shifts in Aperture mode and shutter priority, but I'm getting older too,,
