Effect of zooming out, on contrast, saturation
Is it just my compact camera (Canon SD800) or is it generally true that when you zoom out you get reduced contrast and saturation in your images?.

Does the quality of the lens have some impact on how much is lost as you zoom out?.

Thanks..

You should suffer NO reduction in saturation or contrast simply from zooming. I suspect that some metering variation is the likely culprit for the change you describel.

It could happen if you're shooting into glare - ie if the sun is anywhere in the 180 degree field of view from where you're shooting..

Zooming out usually refers to zooming wide (showing farther away) while zooming in refers to zooming telephoto (showing closer up)....

In other words, you would "zoom in" on a lion at the zoo and "zoom out" to show a whole field of flowers....

My apologies if you are aware of this and zooming out *is* what you really meant....

With that said, if you really mean reduced contrast and saturation when zooming out (going wide) it *could* be because you have more of the sun in your image which could wash it out a bit....

Just a theory....

Bob... Thanks. I was completely wrong. I was taking "zooming in" to mean pulling the lens "in" toward the camera body!! LOL.

Anyway, does that change things for me?.

In actuality I thought I was getting reduced saturation and/or contrast when zooming IN (as, in zooming in on a distant covered bridge from my position downstream on an other bridge). It seemed when I zoomed out (ie. took a wide angle picture) that I got lots more saturation and contrast... now that could have been because I got a lot more sky in the zoomed out picture or otherwise changed the composition..

Thanks.

At the tele end of a zoom lens, things can certainly get less sharp. The thing that is most likely to reduce contrast and saturation is distance: outside air is filth, turbulent stuff. You can readily see the haze with the naked eye when look at the distance from the top of a hill; you will get a percentage of that haze even at shorter distances..
