Honesty is encouraged, but please be positive in your constructive criticism. Flaming and just plain nastiness will not be tolerated. Please note that this is not an area for you to showcase your images, nor is this a place for you to show-off where you have been. This is an area for you to post images so that you may share with us a technique that you have mastered, or are trying to master.

Please note that image critiquing is a matter of give and take: if you post images for critique, and you then expect to receive criticism, then it is also reasonable, fair and appropriate that, in return, you post your critique of the images of other members here as a matter of courtesy.

Also please note that, unless you state something to the contrary, other members might attempt to repost your image with their own post processing applied. We see this as an acceptable form of critique, but should you prefer that others not modify your work, this is perfectly ok, and you should state this, either within your post, or within your signature.

Images posted here should conform with the general forum guidelines. Image sizes should not exceed 950 pixels along the largest side (height or width) and typically no more than four images per post or thread.

It seems that the more DOF you have the richer the background colour. The subject doesn't have a ton of colour to change it seems, each one looks pretty similar to me.

What was your light source? If it was daylight then the amount of clear sky/sun/clouds providing illumination to your subject will vary the colour balance a bit. If a cloud covers the sun, then the colour balance will shift towards the blue compared to earlier shots without the sun covered.

I notice the exposure varies slightly across the frames, that will sometimes change the apparent colour balance a little too.
Also if using auto settings for colour balance, the camera will be changing the colour balance slightly depending on the illumination..

so many variables!

Perhaps you should have done a pre-White Balance before each shot with the different lenses.

Anyhow, the 50mm 1.8 wins as i would have expected. :)

If the lighting didnt change, then I'd say it was all down to the camera adjusting the white balance. There is obvious difference in the exposures though, I wonder why that is?
