Hi to all,
All my posts so far especially my Bittern images seem to lack critical sharpness after resizing for web use , at their original
size ( 3504 x 2336 ) the Bittern images are pin sharp both on the monitor and in printed form , will sharpening after resizing help in any way ??? , all the images I've seen here are exceptionally sharp , what am i doing wrong ???

All advice most welcome

Regards
Andy... :confused:

Hi Andy,
I always sharpen after resizing for web.

Sharpening should be the last thing you do before saving. If you are sharpening and then resizing for web output I would guess you will lose a little sharpness. I usually edit my images (levels/curves etc) and save a master as a 16bit Tiff. I then repoen the master - set the profile (srgb for web for instance) change to 16bit, resize depending upon output required (web/print) and then sharpen - maybe trying various techniques (usm/high pass/smart sharpen) to see what one I think will produce the best results. That works for me - although I would guess there may be variations that might produce even better results.

Hope this helps :smile:

Hi Andy,

The best way to sharpen for web in my opinion is to do all your post processing stuff in your TIFF image, then resize the image to 750 pixels on the longest side, and then use LAB-sharpening (wich is smart sharpening in the LAB-channel-"Lightness", and works better then traditional USM), i usually use about amount 0.4 %, radius 150 and then save your image for web.
That should do the trick...

Good luck!
