Take a look at the following two pictures.


The first has more vibrant color, higher contrast and better saturation. This is common for photos that I take inside vs. outside. I've read a little on the topic and have not been able to decide whether it is due to lens flare or my lack of a polarizing filter.

Any suggestions?

Few questions:

- Does this seem to be common to all of your lenses?
- On the lens(es) you have issue with, are the front elements close to flush with the front of the lens, or recesssed?
- Do you use a lens hood?

Yes, it seems common to all my lenses. Here I used a Sigma 24-70mm EX F/2.8 with a Hoya UV(0) filter. I always use the lens hood that comes with the lens when working outside. The front element is somewhat recessed.

If the weather is overcast or a cloudy day have you tried increasing the EV slightly. The conditions work as a huge softbox and tricks your camera to make it seem really bring so it compensates by making everything darker.

The histogram for this image shows it to be under exposed by about one EV. When I bring the exposure up in photoshop it does not help the color or contrast much. The picture still looks flat. Would it have helped to have increased the EV on the camera rather than in photoshop later (the picture was taken in RAW format)?

faidoi makes a good point. If you are seeing this with the lens hood on, then lens flare is not the culprit. In your outdoor example, the light is very soft; even though there is some later afternoon sunlight, the kids are in shadow and the sky is one big light diffuse light source. This will naturally reduce contrast, and your metering system will try to average to mid-gray. You could bump up the exposure a little, but you may wind up blowing out highlights. You are certainly not underexposed much here. I'd just apply a gentle curves adjustment to increase contrast; the improvement on your outdoor shot is dramatic.

Increasing in camera would always be better. I also use a warming filter to give photos a more flattering feel. Living in San Francisco I think it's a must have filter.

Auto-bracketing is the coolest feature to have in bad lighting conditions. I just wished I have it.

I don't have a warming filter but would it be the same to simply adjust the manual whitebalance to a warmer tone or are there subtle/drastic differences?

I wished I had white balance feature other then indoor, outdoor, hold, auto. One of many reasons to think about upgrading :)
