Camera Calibration - Fors script.

[Denis de Gannes]

Many months ago I ran the "Fors Script" in PS CS to obtain calibration for my Olympus E3'' (support was provided for this camera in ACR 2.4) and this has worked well for me.

I recently purchased an Olympus E51' (support provided in ACR 4.3.1) and need to produce calibration settings for this camera.

a. Is it necessary/important that the script be run in PS CS3 bearing in mind that LR/ACR 4.4.1 has updated camera profiles?.

b. Would I get the same result if I converted the .orf to .dng with the latest dng converter and run the script in PS CS?.

c. Is it advisable to run a new calibration for the E3''?.

4.4.1 hasn't changed much in the middle temp range where you'd likely be running the script - it affected the extreme ends of the range - so whilst technically you should possibly run the script again, I'd be very surprised if you saw any difference in the results.

Thanks for you input Victoria. I gather from your comment that I would be just as well off using my PS CS to run the script as opposed to trying to have a friend with PS CS3 run them for me.

The other thing is that there is a new version of the script v 1.2 which was issued in Jan 15 2''8 and requires CS2/3 to run. The site however does not say if it produces improved/different results.

Check out the Rags Gardner version of the fors script.

I have run this with my 5D with ACR 4.4, and the results are an improvement to previous calibrations.

The new Adobe camera profiles provide slightly different default conversions, I believe that updated calibration(s) will improve on the new base.
