DxO Program

[Beeclose]

Hi, Has anyone tried the DxO print improvement system, I have just started using it and it is amazing, it suits Canon users as it has correction modules for lots of Canon zooms and for what it does,it is not expensive, just log onto" DxO Optics" web site and they will show You what it can Do. EW.

Today I tested the DxO software (evaluation version) using pictures taken with my DRebel (D300) and my Canon 17-85 EF-S lens. I used the default processing options to batch-process some pictures I took during a recent trip. I have these observations:

1) The software did a good job correcting lens distortion. (The 17-85 Canon lens is notorious for barrel distortion at the WA focal-lengths and pincushion at the telephoto setting.)
2) The software did a good job of correcting vignetting at the WA focal lengths.
3) The software did a good job of correcting noise at the higher ISO settings.
4) The software did the best job when fixing photographs taken at WA focal lengths, maximum apertures, and high ISO.
5) At longer focal lengths, lower ISO, where the lens performs best all by itself, the software seemed to overcorrect image contrast and sharpness.

Summary - the DxO software to be very useful for fixing photographs taken under low light, low contrast, wide-angle situations. These are the situations where the lens has the most problems. When photographs are taken, properly exposed, under good lighting conditions with small apertures and high shutter speeds, the DxO software does not help, except perhaps, to correct CA and barrel/pincushon distortion.

It sure works well with under exposed shots, last one I did was grossly under exposed and when processed it came out great, I tried it with 28-105 USM at 105, on a landscape, the corrected one was so much sharper than the original, I am waiting for the update to come this week.
