OldHickory30 Posted February 16, 2016 Share Posted February 16, 2016 When I import a 8bit Tiff image, into AP, it might be an excess of 200mb however after retouching it, exporting it back out as an 8bit tiff image , its reduced to 21-26mb. That is a significant file reduction, something has to give, why the reduction, what's being constrained? They are both the same file! Is AP compressing it?

barninga Posted February 16, 2016 Share Posted February 16, 2016 ap compresses tiff files with ztiff, a non-lossy compression algorithm. this should explain the difference in size. Quote take care, stefano Link to comment Share on other sites More sharing options...
OldHickory30 Posted February 16, 2016 Author Share Posted February 16, 2016 Thanks, but what if if I don't want it compressed, which I don't! Quote Link to comment Share on other sites More sharing options...
R C-R Posted February 17, 2016 Share Posted February 17, 2016 As long as the compression is lossless, why would it matter to you if the file is compressed or not?

OldHickory30 Posted February 17, 2016 Author Share Posted February 17, 2016 Because a true photo editor, should allow me to make that decision, and be forced to use a specific format of compression. Quote Link to comment Share on other sites More sharing options...
R C-R Posted February 17, 2016 Share Posted February 17, 2016 I do not know what you mean by a "true photo editor." Lossless TIFF compression has no effect on editing. The only reason I can think of to avoid it is if the editing app is incapable of processing the compression/decompression efficiently.

OldHickory30 Posted February 17, 2016 Author Share Posted February 17, 2016 My RAW processor and PS, allows me to make that decision, the way it should be, I'm not interested in debating the quality of the format or compression, only that I should be allowed to make that choice....Period!

lhodaniel Posted March 17, 2016 Share Posted March 17, 2016 Agreed that there should be a choice! One reason I don't want mandatory compression of tiff is that Capture One Pro 9 will not show it. In fact, it crashes the program. I will be using C1P as my raw converter. and DAM. I want to be able to replace Photoshop with AP, but I can't export a tiff in AP and view it in my C1P catalog. This is a deal breaker! I can open and re-save the tiff without compression in Photoshop. But, if I need Photoshop then AP is of no use to me.

anon1 Posted March 18, 2016 Share Posted March 18, 2016 http://help.phaseone.com/en/CO8/Output/Process_Files/Learn_More_settings.aspx " TIFF files can be compressed. A TIFF is a lossless format, as are both forms of TIFF compression; LZW and ZIP." I think that´s what also AP does so it should be able to read it...?

lhodaniel Posted March 18, 2016 Share Posted March 18, 2016 It looks like Phase One just fixed it with today's v 9.1 update. Improved tiff support is one of the new features, including alpha channels and layers. Phase One mentioned that this would improve compatibility with AP by name, so I gave it another try. I exported an .afphoto to 16-bit tiff (no layers) and C1P imported it with no problem. So, I feel better. :) A few days ago that would not work with C1P 9.03 on the same file. I was able to get it to work by opening in PS, re-saving without compression, then importing into C1P. I would still prefer a choice, though. I historically have never used LZW in PS.

anon1 Posted March 18, 2016 Share Posted March 18, 2016 Thanks for the info!I'll give it a go tomorrow as I can get it for 50€ for Sony cameras which is what I'm using and I'm so far pleased with C1s interface and options so it's time to really dive in now.Also affinity layered TIFFs will give an acceptable compatibility (they plan to embed the affinity proprietary layer information in the tiff just like PS does with its layer data) this might give a reasonable archive workflow till affinity gets the DAM done. btw: I found this tutorial quite helpful https://www.youtube.com/watch?v=m6KqYfjVt50 Quote Link to comment Share on other sites More sharing options...
anon1 Posted March 20, 2016 Share Posted March 20, 2016 So now I´m on C1 and Bridge (free) and it seems to work flawlessly. C1 has some strange stuff going on but after 3h I´m feeling confident now and it´s all set up and ready to go! Tethered shooting with a Sony Camera works great, I wish Affinity can do this one day with their DAM as well! C1 is reasonable fast and more importantly it keeps my MB nice and silent (totally eats up RAM though) so I´d feel like I could use it without a power connection for some time (not so much with AP where I´m doing more intense editing). Now I´m looking forward to APs implementation of layered TIFF and ultimately for the Affinity DAM, but I´m a bit more chilled now and finally shooting RAW, such a great enhancement! https://forum.affinity.serif.com/index.php?/topic/11105-round-trip-with-capture-one/?p=80899 Saving back to TIFF with Affinity layers will be available in Version 1.5. Coming soon. -Ben Quote Link to comment Share on other sites More sharing options...
