Processing 16bit files in ACR?

[Mark_Se]

I recognized that i can open my 16/48bit scans in Adobe Raw Converter. It seems that i can do the same things (white balance for example!) i can do with digital raw files. The results look awesome so far! Does someone else of you work this way? It looks like i do not have to use cc filters any more...

Sure when the image calls for it, but it is best to correct as much as possible at the time of making the image.

Yep works great!

is there technically a difference between 16 bit /48 bit files and real digital raw files?

[Frank Petronio]

Unless you're shooting from a medium-format digital back, all the DSLRs are 12 or 14-bit at best. I don't know what an Espon Scanner really is. I think a good drum scanner (not all of them) will deliver true 16-bit information.

It doesn't matter, you have to manipulate the image. I like using ACR because you do all the moves in one operation, which is less destructive that making a dozen or more smaller moves in Photoshop.

I think. I gave up trying to be definitive, I just do what works.

I missed using ACR, when switching back to film...

numpty question - how do I do this then? I use Silverfast as a CS5 plug in, and I also use Nikon scan for 35mm which gives me TIFFs. These open up straight in CS5 rather than using ACR - what am I doing wrong - do I need to save as a different format?

David, you can set up ACR in Photoshop to open JPEG and TIFF files in addition to RAW files. For this, go to the Camera Raw Preferences (by clicking on the Camera Raw Preferences... button in Photoshop's File Handling preferences). At the bottom of the Camera Raw preferences window, you can set your preferences for JPEG and TIFF handling.

Cheers,

cheers - I'll give that a go!

On Mac-CS5 I open them into ACR from Adobe Bridge, Apple-R allows you to open them in ACR or double-click to open directly in Photoshop.

And after you open an image and save it to a file in Photoshop you can still re-open it in Camera Raw by right-clicking on the thumbnail in Bridge and clicking on the menu line that says something like "Open In Camera Raw." Just in case you like working with some tool or feature in Camera Raw better than in Photoshop.
