Click on EXIF Data on the right hand tab and see if that shows what you want.
On EXIF Data I don't have anything. What is it ?
I can obtain Histogram of photo. Is it useful as image quality parameter ?
Thanks Emil for getting back to us. I have started the debate here (link below) and I suggest join the group and continue it. With Tamlin and the others you will have your answer

Thats a large question and demand. Could you be more specific in what parameters you mean. You really need a photographic forum/information that strips these things down. Also you have to take into account lens's. Too many parameters are going through my mind, sensors, lens's aberrations. I shall await your reply

I will explain with more detail. I made some photos with one camera and two different lens. Resolution of photos is 640 x 480. I would like to know
which photo I can get more information. I am making some experiments in fluid mechanical field (jets) so I would like to know which lens is the best
for me. If I can get a lot of information of photo it is better for me. I don't know exactly what is important for me (histogram, etc...). Do you
know some good photographic forum ?
If your looking at lens's then fine there are many charts you can download to ensure that the lens you choose it the that will do the job as detail is critical. This is one I used back in the '70's

Its an original lens chart. Look around for more and then the best assessment you have is your eyes. But, even here there are many aspects to resolving lens quality. What is important to you?
The above is a start. But the discussion is on about this in BioRUST it is turning out to be interesting would welcome your input.

I have done some probes with this chart: http://jimdoty.com/Tips/Equipment/USAF_Test/USAF_Chart/usaf_chart.html.
I have 2 kinds of lens, lets call them 1 and 2. Here you can see results: 1: http://img224.imageshack.us/my.php?image=1tablehr3.png and 2: http://img222.imageshack.us/my.php?image=2tablefo7.png.
Here you can see images: 1: http://img219.imageshack.us/my.php?image=42405763pw8.png and 2: http://img230.imageshack.us/my.php?image=93888841gq1.png and here you have respective histograms: 1: http://img227.imageshack.us/my.php?image=histogram1jz6.jpg and 2: http://img147.imageshack.us/my.php?image=histogram2tb5.jpg.
What do you think ? Can I get some conclusions of 2 lens ?
