I work at a printing company and we're looking into acquiring Affinity Photo to replace our aging PhotoShop CS2 that we use to process artwork from customers and convert it into a format that can be imported by our main design program used for production (Mecca2000 http://www.amgraf.com/pages/m2k1.html). Mecca treats bitmap tiffs differently than grayscale tiffs and displays them on screen with the white portion of the image being transparent which makes them easier to work with when things overlap and they take up much less file space, but if they're grayscale (which seems to be the closest Affinity Photo can do) they display with the white background to the image with no transparency and every operation on them takes longer than it would in monochrome and certain options like raster tracing aren't available to grayscale images. This comes up quite frequently for us when we're printing solid single color customer logos. The limitations of the aging Mecca program aside, we need to be able to convert an image down to bitmap color mode and export a "monochrome" tiff in Affinity Photo like we can in photoshop. In photoshop the mode menu has an option for Bitmap which then brings up a dialog with different options for how to convert it down to an ONLY black or white image (no levels of gray in between). Below are images showing where this mode option and subsequent bitmap dialog are in photoshop as well as images of where i expected to be able to find them in Affinity Photo, but couldn't. It may well be that Affinity Photo can already do what i need it to and i'm just missing something due to my inexperience with the program, in which case i'd be grateful if someone could point out how to output a bitmap/mono tiff. PhotoShop: Affinity Photo:
Summary: The image is 4988 x 2814px, 14.04 MB, 7 layers: 1 background pixel layer, 5 masked curve adjustment layers, 1 B&W layer in RGBA/32 (HDR), ProPhoto RGB (Linear). Using Document, Color Format to convert this image in 32-bits to 16-bits RGBA/16 - ProPhotoRGB takes over 8 minutes of processing time on a relatively well-spec'ed machine. Adobe Photoshop CS6 using the same image in 32-bits, similar number of layers and same color space to 16-bits in same color space takes about 5 seconds. Affinity Photo takes an inordinately long time that is not acceptable for the workflow. Details: The machine: Windows 7 Professional 64-bit up-to-date per Windows Update Service Pack 1 Processor: Intel Core i7-3770 CPU @ 3.40GHz 32.0 GB RAM Windows Experience Index 7.7 (on a scale of 1.0 to 7.9) Graphics card: GeForce GTX 970 version 385.69 NVIDIA Control Panel reports (see attached PNG) More details on machine in attached PNG. Disk C: is a SSD and has both Affinity Photo and Adobe Photoshop CS6. The software: Affinity Photo 188.8.131.52 RAM Usage limit 25,599 MB Renderer: Default (NVIDIA GeForce GTX 970) Adobe Photoshop CS6 64-bit, using the NVIDIA GeForce GTX 970) Using Photo Affinity's Document, Color Format, RGB 16 bit it takes slightly over 8 minutes to have hourglass disappear and the RGBA/16 - ProPhotoRGB to appear. During this time Windows Task Manager reports (see attached PNG's). CPU utilization by Affinity Photo is essentially 100% during this time. Trying 32-bit to 16-bit conversion on the same image in the beta version 184.108.40.206 (Beta) does not result in Task Manager reporting "Affinity Photo (not responding)" but if anything the conversion takes even longer at about 8 minutes 55 seconds. Doing this 32-bit to 16-bit conversion of same image and same color spaces in Photoshop CS6 takes about 5 seconds of processing time. Machine Info 1.pdf
The export options for TIFF files always remember the last setting, rather than defaulting to the document color mode. I.e. if the last export was CMYK, the default the next time will be CMYK, even if the document is RGB, and the other way round. This is dangerous since it makes it easy to perform unintended color space conversions on export. Especially beginners who may not know about RGB and CMYK or just trust the default export settings might be in for a nasty surprise. Ideally, the export settings would check if the color format in the export settings is set to the same thing as the same as the document color format and in that case offer the document color format of the next document the next time. If the user changes the setting to something else than the document color format, it would offer that specific setting the next time, regardless of document format. That way it won't get in the way of, say, someone trying to manually export 10 RGB documents as CMYK, but it also wouldn't catch someone exporting an RGB file to RGB TIFF by surprise if their last export was a CMYK document to CMYK TIFF.
