What is the best way to process files in CS5 jpeg, tiff, or psd

Aug 20, 2012 4:38 PM

My camera out put is in Jpeg I have no choice. While I can process jpeg with no problems in CS5 is there a better way to do this? would I be better off converting the jpeg to either tiff or psd and then process the file and then reconvert back to jpeg as the final product. I have heard so much about "lossy"(jpeg) vs "non Lossy" (tiff and psd) which are the ones I want to use? Am I on the right track

    Wayne Fulton has some excellent advice and covers this topic well.

    Aside from that always set your camera to the best quality jpeg setting. Converting to lossless formats does not lose jpeg artifacts if the image was low quality jpeg to begin with.

    No,the loss comes in reediting and resaving the jpeg,not transferring it.

    One last thing, Resolution and jpeg quality are two different settings in your camera.

     

    640 x 480 pixel settings would be low resolution,while 3000 x 2000 (6MP) would be max resolution in some cameras.  Pick the highest setting. Better to reduce than enlarge. Overhead is good.

     

    Jpeg quality would be something like lowest to highest jpeg compression setting,but it's usually described as Normal,Fine,and Superfine. Take "Superfine". Most storage cards have much more capacity today and it isn't as costly.

    A touch of realism from me.  If you are going to make enlargments less then 11x17 a person would have a hard time telling the difference between Normal and Superfine jpeg settings.  Same with saving jpeg with 9 vs 12 quality settings.  But there is a significant difference in file size between 9 and 12.  So the expected end use, and how much hard drive space you want to devote is the real driver. 

     

    If you were a perfectionist you would burn the original to several disks and archive in different places (and resave evey few years to minimize degredation).   Then with the copy you can save smaller flies knowing if you have a need you have the original at HQ saved.
