Title: Demo user QImage Ultimate Post by: Steinr on March 15, 2021, 01:38:20 AM Hi, I just downloaded QU and just started learning.
I have a made some panorama photo and saved them in big Photoshop files 7-40Gb PSB format. I guess I might have to install a plugin in PS CS6 to be able to print. Is there a way I can try the plugin?

If you save the files as TIFF and they are under 2GB, you could give it a try. What size prints are you printing that require a 40 GB file?
An example: 2GB will allow you to print a 24 inch tall pano that is 213 inches (7 feet, 8 inches) long at 360 PPI. I ask what size(s) you are printing because I find that sometimes people create massive files that just increase overhead without increasing print quality.

My Files is panorama stitched with 250-300 photos 50Mbpixel (Canon R5). Latest is 216500 x 121800 pixel = 26 Gigapixel a few bigger and some a little smaler. I also gone test an 2x extender on the 800mm f11 Canon. I can often reduce files size to 4-8gb, but 2gbit is no option. I can print from Photoshop, but I was thinking a RIP software might could help me with a better structure on printing. If 2Gb is max, I must look other places or forget it. Thx.

A 216500 x 121800 pixel (79 GB) image is good for a 60 foot by 28 foot print: and I don't know of any 28 foot wide printers. If you have, for example, a 44 inch wide roll printer, that same image can be saved at 28156 x 15840 (1.3 GB) and printed at 78 x 44 inches (360 PPI) and you'd end up with the same print quality compared to using an image that is 60 times too big for the job.
