EV and ISO

I shoot a lot indoors and in poorly lit situations. Not to mention my dog has black fur, which is impossible to get in low light.

I've been trying lately to compensate for this lack of light by increasing the EV on my k-5. The issue I've had is that as I increase the exposure, the ISO value also kicks up, automatically (I usually shoot in tAV mode), and in the end the picture doesn't 'lighten', but rather is now grainier. What should I be doing?

Don't shoot in TAv mode but instead lock the aperture at close to wide-open in Av, fix the ISO at something with minimal noise (i.e. ISO 800-1600) and then use the EV shift to make your image brighter. The K-5's SR should allow you to get good results at as little as 1/20s hand-held.

Also, make sure you're shooting in raw.

Further to Adam's (as usual) top flight comment, try spot metering the dog's fur and adding two stops of exposure (EV + 2.0). This is a warped take on Ansel Adams' zone system, and should get you in the ball park for starters. Tweak until the fur looks the way it should.

I'm confused. Wouldn't you go -2 EV on the exposure compensation? I think he wants his dog's fur to look black, not 18% grey or something like that.

To be fair, I just wanted to point out its tough to take a picture of a dark subject in low light. Trust me, I have enough pics of my dog.

That said, thanks for the answers everyone. I'll be sure to try out the suggested methods.

Yep, underexpose dark things to keep them dark. The actual meter mode does not really matter. Use a different shooting mode, and just take a test shot and adjust EV according to the result.

Another suggestion is the lighting. If you can position a bright light above and just slightly behind the dog it will add a glossy look to the fur and give it more dimension. Just make sure you meter to the subject and not the rim lighting.

. Yes. mumble. With my "solution" the dog would come out white or light grey. I get so confused ....
