Good Morning All,

firstly, many thanks for the UA's and for the HC, votes, views and comments on my last upload.

This one is from an impulsive trip to the boatyard in Heswall last night. I have tried to desat as much as can get away with without losing the light on the boat. Tricky one to process. It's a 3 shot bracket sent through photomatix and then tweaked and tweaked a bit more in PS.
If my jpegs are sharper than my RAW's does that mean I need my lens looking at?
Thanks for looking
Mand.

As you probably already know jpegs have some sharpening applied "in camera" and generally speaking RAW will need some "capture" sharpening applied to compensate for the de-mosaicing process so your lens is probably OK Smile

a fantastic picture, wonderful atmosphere.
IT is not your lens, check the sharpening setting(s) in your camera.
I have turned sharpening off for both, I prefer to do it gingerly in PS or LR.. meaning I apply it only if needed.
Don't forget that pictures sometimes loose sharpness in the upload, I don not know why.. there seem to be less pixels in the uploaded version.

thank you Jeff! De-mosiacing process.. well, you learn summat new every day. Must go and nerd up about that.
Annette, thank you. I only noticed as I tried two ways of processing and used the jpegs for the photomatix blend and just opened the RAW. Big difference.

Sharpness is lost in the re sizing process, not the upload. The re sizing causes the image to be compressed into a smaller file size, so you need to open the new file and check sharpness before you upload, Then apply sharpening as needed. Most images, except those that are exceptionally sharp to begin with will need sharpening after re sizing.

JJGEE is correct, RAW = RAW, no processing has been applied, including NO sharpening while the JPEG IS processed according to the settings you have chosen. ALL digital photos are slightly softened by the anti-alias filter (Moire filter) and the Bayer pattern filter that are in front of the sensor. JPEG sharpens to compensate, RAW does not. Some cameras have removed the anti alias filter (its used to prevent Moire effects on patterns in images), like the Nikon D800E, which needs further post processing to remove moire if present, and the Fuji X-Pro 1, which needs no further post processing due to a re designed Bayer pattern filter array. Both produce quite sharp RAW images.



Regards



Willie
