How to create large image while maintaining resolution?
Hope this is a softball, but I am new to design and am having trouble creating a large detailed image that maintains details when zoomed in. Basically I want to create a large fictional map that I can display on my 85" inch TV, but maintain the ability to zoom in on landmasses without it turning into a pixelated mess.
I've tried scaling up the image to UHD, but that doesn't seem to help. The other option I was thinking could be to adjust the image print resolution, but it seems like the PPI is directly linked to the print size, and there is no way to increase the scale of the image without cratering PPI. Do I just have to start with the canvas size set in inches to match my TV? Surely there must be away to adjust existing images for this purpose?
