Handling HUGE (!) maps

[SteffenBrand]

I am pretty sure you can work in 150 dpi or lower.

I seriously can't, I have no choice here. 300dpi is a guideline here, I can't change that.

Thank you all, the issue has now been resolved. I gut a new Windows-PC paid by the company I work for now full time from home office, that is really high-end - now at home. 4,0 GHz, 32GB RAM, 500GB-SSD, etc. is probably the best you get for a reasonable price. I think it will force me to split them up in 4 parts, but at least it won't be a huge pain to work on it. I think I will try some of your suggestions and let you know which of them worked for me, maybe I even make another tutorial. We'll see! =)

Thank you guys so much!
Steffen

By the way, I think the latest photoshop allows the use of Linked objects as well as smart objects. This means that you don't have to deal with such heavy files.

your image 19857x28076 is not all that HUGE
big but not huge

the normal medium size i use is 16384x8192 to 32768 x 16384

for images larger than 4 gigs .I have worked with images that take up 25 + GIGS of drive space for a single image

normally these tend to be 16 bit or 32 bit floating point images that are 131,072 x 65536 pixels

there is a nice image tool explicitly designed for things this size and multi layer data

originally it was used with art preservation in taking multi spectral images of paintings in VERY high resolution

i use that for things that need doing to the whole image , then crop out a working area and use Gimp on that then paste it back in .



on windows you WILL!!!! have a major issue of "windows explorer" trying to make a thumbnail of a 10 to 20 GIG image !!!!

that will bog your system down to a crawl !!!!( or stand still)
and big images DO AND WILL crash windows explorer
expect a crash about once or twice a day when working on big images
-- at least that was my experience using Microsoft products
