bono0272 Posted November 13, 2006 Share #1 Posted November 13, 2006 Advertisement (gone after registration) Hi DMR users, After shooting RAW by the DMR, usually what format do you convert to? JPG or TIF? When converting the DNG files to TIF thru Capture One, there are options of choosing 8 bit or 16 bit TIF. However the 16 bit TIF cannot be further convert to JPG but the 8 bit. (I am using Photoshop to convert the TIF to JPG) How often do you convert the DNG to 16 bit TIF and what usage do you usually use the 16 bit TIF for?

cbretteville Posted November 13, 2006 Share #2 Posted November 13, 2006 Richard, You do all the editing you have to in 16bit, thus preserving as much information as you can and giving you as much headroom to work as possible. After you're done, save the result as a 16bit tiff. Then you can change the file to 8bit (click on: Image|Mode|8 bit/channel) and save as Jpeg (make sure you don't overwrite the tiff file) for web, email or whatever. This way you can go back to the edited TIFF and do more work as you please. As the tiff file dosen't loose infdormation with each save as is the case with Jpegs you're allways starting out fresh. - Carl Quote Link to post Share on other sites More sharing options...
andybarton Posted November 13, 2006 Share #3 Posted November 13, 2006 An alternative is to use the Photoshop native ".psd" format, which is also lossless. 8bit jpgs are just about the worst format that you can save a file in if you want to do any editing. Every time you save a jpg, information is lost. Quote Link to post Share on other sites More sharing options...
bono0272 Posted November 13, 2006 Author Share #4 Posted November 13, 2006 I see. Will try the 16 bit to 8 bit conversion tonight. Thank you very much. Quote Link to post Share on other sites More sharing options...
mwilliamsphotography Posted November 13, 2006 Share #5 Posted November 13, 2006 I just shot a job with the M8, DMR and Leaf Aptus 75 digital back on an RZ. All RAW. My preffered processing engine is PSCS2 because it recognizes all of the file formats of all my digital cameras ... including the Leaf Aptus 75 MOS files. I select 16 bit tiffs for conversion when I am providing clients with full res output, or am going to do further retouching in Photoshop after conversion. When all of that is done, I then use the Image Processor in Adobe Bridge Browser to convert all the tiffs into 8 bit jpgs. Those are provided to clients for convenience. Loading and viewing 4 gigs of tiffs verses 500 meg of jpgs makes a big difference in speed. I NEVER archive the jpgs unless it is just vacation snapshots. However, once jpgs are archived to a read only CD or DVD, they can be opened over and over without further loss of quality. Quote Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted November 13, 2006 Share #6 Posted November 13, 2006 For delivery to clients I give them the High rez 16 bit Tiff files and i also run a action in PS to make low rez jpegs of the same file. This way they can edit and chose what image they want to use and pull the Tiff for the printer or other media. I make the jpegs small enough so they really can't use them for the print work. This keeps them from making a dumb mistake . jpegs are for 3 things in my book editing , web and Powerpoint Quote Link to post Share on other sites More sharing options...
