Convert 16 bit to 8 bit photoshop9/22/2023 ![]() ![]() They expose photopaper using RGB lasers, then they are wet processed like regular photos but in much larger sizes. You say you are using a “lab.” That term usually signifies a start in the wet processing era and they may very well still have a Durst Lambda printer or a working Lightjet or Chromira. It is used for photographic images that are still wet-processed. Again, once an image is saved in CMYK all the outer gamut information is lost forever. Handoff in ProPhoto or even Adobe RGB 1998 will give you a better result than starting in CMYK. A lot of CMYK machines in wide format or photo-digital have a much wider color gamut than press-CMYK and you will never have the specific profiles a printer may be using. The ideal scenario is to have an image in RAW and convert it to ProPhoto RGB, do your work and let the lab do the conversion before printing to their own color profiles. We never use sRGB as a preferred color space because it may as well be CMYK it is so small. A printer shouldn’t be converting a CMYK image to sRGB.Converting to RGB does absolutely nothing for that image as far as color quality. Once you save that image, you cannot get those colors back. If you convert to CMYK you lose color gamut.You often cannot place a 16bit image into a layout program.Īs for all your CMYK/RGB questions you are really confused. ( ie.Depends on what you are doing with the photo. Some versions of the very cheep photoshop home use versions will run in wine Unfortunately “shopping” 16 bit images on linux is still a bit difficult Nip not so well documented but has a wiki and a blog There is a bit of a learning curve to this programĪ terminal based image lib/program like “Imagemagick”Īnd is fairly well documented ( the code is almost as well documented as the apache server code ) It is like a cross between a spreadsheet and imagemagick show originalīut enough of ubuntu ( i do not use it. ![]() cinepaint-csv-ubuntu.sh echo ubuntu-cvs.sh - install from CVS source on ubuntuĮcho INSTRUCTIONS: This script downloads and builds CinePaint from CVS.Įcho If you are a member of the CinePaint dev team, you want cvs-dev.shĮcho Expect it to take hours to download and build cinepaint from scratch.Įcho Fetching cinepaint from SourceForge CVS.Įcho Press when prompted for CVS password. ![]() there are a bunch of hits like this one.You might want to do a search on the Ubuntu forum It looks like debian removed it after “etch” do to the custom gtk1 requirement I use rpm based distros and it is in the fedora ,rhel and suse repos One that GTK developers custom created JUST for cinepaint To build Cinepaint requires a very special CUSTOM version of GTK1 The 32 bit Imagemagick w/ Octave sounds interesting, but Octave appears to be a language? I want to be able to manipulate them (mostly basic ops like sharpen/blur/some color manipulation, etc.) Being able to work in 32 bit would be even better!ĮDIT: Could you explain more about these tools? I tried Nip2 and Gmic, but they appear to be CLI-based. I thought you could just get them through Google Earth but it seems not.Īnother use is that I am working in Substance Designer, and I am outputting 16 bit images. But I am having a hard time finding good terrain maps/height maps online. Yes, I am definitely trying to do more with DEM’s. ![]() Gmic - NOT!!! the 8 bit gimp plugin but the 8,16,32 bit terminal tool For 16 bit( signed and unsigned ) and 32 bit float i use a custom built Q32 version of Imagemagick for working with images in Octave ( a opensource version of Matlab) ![]()
