I am preparing an Exhibition in v1.5b1. The photos come from a Canon G3 camera, shot in Raw, converted with BB (all settings neutral), and then corrected in PS with Autoeye 2.0 and Color Washer. The files are then saved in jpg with 10 quality. No resizing nor sharpening are applied.
This files are directly fed into EE. Sizes path are set as:
micro (Imagemagick 480 USM)
small (Imagemagick 640 USM)
normal (Imagemagick 800 USM)
big (Imagemagick 1024 USM)
In most cases I see that the images have been oversharpened by mogrify; in some cases the halos are very noticeable.
Inspecting the php coding, I see that depending of the size of the image, the software assigns a "$sharpness" level from 0 to 9, which is the translated into usm parameters before calling mogrify.
By tweaking with the assignation of the sharpness level (using 2-3 levels less than default), I've been able to produce good looking photos.
But obviously, sharpening depends on lots of other factor. For example, if now I try to use photos from my D30, the requiered sharpness levels may (or will) be different. Conclusion: hard coded sharpness levels / usm parameters are not practical.
So, all this is just for asking Pekka if there will be a more flexible way to tweak this parameters in the final version, in order to adapt them to different cameras, shooting modes, workflows, etc.
Thanks in advance
