hi guys,

question lang... i'm quite new in the hobby... 26 days to be exact :) since i got my dslr... anyways... just would like to ask for advice in post processing raw images. i shoot with my 350D with sigma 17-70mm f/2.8 in raw format. my shots would be sharp and clear in raw format when i view and edit it using the bundled software (digital photo professional) of my 350D. but when i save it in jpeg (350 dpi, highest quality/resolution) the resulting jpeg file would not be as sharp as the raw images. can you please give me advice as to what i'm doing wrong and how to correct it? thanks! :)

p.s. i could post raw image and processed jpeg shots i just don't know if posting the raw image (which is huge) is allowed on the forum.

when you convert an image to jpeg you automatically lose information from the original raw file. if you would like to retain the information from your adjusted raw file or original i suggest saving it non compressed file types like TIFF.

hi amboy!

good to see you here. just joined a few days ago. happy shooting!

When you open up a RAW file untouched or unedited and save it to a Jpeg... It would definitely lack some punch in saturation and sharpness to it; coz by default, a camera doesn't apply these settings to a RAW file. You have to do it then in post processing before you choose any format you want to convert to. :)

Probably also why you are getting lesser quality images in your Jpeg conversions--are the settings you use for Jpeg compression... Try to check that... :) HTH

hi earl! i usually do minor adjustments on sharpness/saturation while still on RAW format then i save it to jpeg. when i save it on jpeg my setting would be set on highest quality and 350 dpi but i would get a less sharp image compared to the processed RAW image. however all other tweaking would be saved on jpeg. what i would normally do is to do USM on PS to sharpen the jpeg again. am i doing something wrong here?

@JPSarmenta

i actually tried saving it to TIFF file na before, however compared to the saved JPEG file (of the same file) the jpeg looked sharper. :(

@ Amboy - you should try the conversion using ACR. :)

hi earl... what's ACR? :Dum:

ACR is Adobe Camera Raw its a plugin for Photoshop for processing RAW, you can download it at Adobe website.

There are other RAW converters in the market and the one I am using is Bibble Pro a trial version can be download at this website http://www.bibblelabs.com/

hi earl... what's ACR? :Dum:

It's Adobe Camera Raw! A plugin for Photoshop...

Another good alternative would be: Adobe Lightroom... It's workflow is more photo oriented as compared to PS which tackles something broader. :)

do you adjust the highlights, shadows and midtones of your images also? it is best to do that in camera raw. don't forget to choose prophoto rgb or adobe rgb as your color space. bigger gamut the better!

hi JP. i usually don't. most post processing i do (on raw) is on sharpness/brightness/saturation only. ok on using adobe rgb instead. will give it a go... thanks! :Grin:

Anytime you digitize something you lose sharpness. The experts will tell you to do a round Capture sharpening when you open the file in Photoshop. Sharpening in RAW, especially in ACR is pretty rude so you may be best to turn off sharpening there. Steop number one in Photoshop is to do a mild sharpen, most preferably an Edge sharpen to prep your file prior to editing.

well another trick in sharpening is fooling the eyes. when there are very distinct differences in the whites and blacks of your picture, you will notice that your image is sharper. seems true with my observation. :) just correct me if i'm wrong adobe ps gurus.

Actually you're correct here JP. You can paraphrase what you said in techno-babble lingo by saying defining and optimizing shadow and highlight detail. :)
