"Exposure Compensation Versus Higher ISO" Mon 09-May-11 07:57 PM by J_Harris
I've been expirementing using my new D7000 in lower light situations like cloudy, hazy days.
What is your opinions on which is the better option to brighten a picture without decreasing its overall quality, raise the exposure compensation or raise the ISO without going above ISO 400? I shoot using aperture priority, and always ensure my shutter speed is at least 1-1/2 times greater than than the focal length.
I prefer not to use Active D-lighting at this time.
P.S. Has anyone else got so frustrated with accidentally hitting the DOF button, that you changed it to another function?

Increasing ISO won't give you a brighter picture, it will just increase the shutter speed for a given aperture. You might want to add exposure compensation AND increase the ISO to keep the same shutter speed for the aperture.

Exposure comp and increasing ISO don't do the same thing. Using exposure compensation is telling your camera to over or under expose an image from what the camera wants to do. Raising the ISO is increasing the sensitivity of the sensor, so to speak. If you raise the ISO and let the camera do its thing, the exposure will be the same (same brightness); the camera will either closing down the aperture or increase the shutter speed to get the same exposure (brightness). If you add + compensation you will increase the exposure (increase brightness); the camera will either open up the aperture or decrease the shutter speed to get a brighter image.
Perhaps more simply, if you up the ISO and do nothing else, the camera will compensate and the exposure will be the same. You need to use + compensation to increase the brightness, or manually use a larger aperture or slower shutter speed.

Hello Jerry, I had an AE1 for many of years until I wore the thing out and really loved that camera and the photos that it produced with the 50mm lens I had with it.
If the camera was set in manual mode, you set the shutter and aperature and then you raised the ISO you would get brighter shots with each rise in the ISO. Any reason why ISO 400 is a ceiling? You can pretty much go to 1600 with almost no noise at all and I have gone as far as 6400 with excellent results.

I'm always hitting the DOF button inadvertantly, but I haven't reprogrammed it. I think it's a function of the small body and my own clumsiness. Didn't have this issue with my D200, but I'm gradually learning to use the 7K more efficiently.

My biggest problem on the D7000 is the Mode dial. I manage to accidentally hit it without realizing it and end up on A when I set it to S. I wish it had the Release Mode Dial feature or that it was a little more resistant to a brush of a thumb.
I've also been getting very good results at ISO1600. I even been pleased with ISO2500 in some lighting situations.

This is exactly what I got when I did this experiment using manual mode with D lighting off. Here are the results of the images. I intentionally left the living room darker to see how the camera handles noise when shooting in darker areas especially with shadows. Click on the images for larger view.
