Help! I have large format TIFF files of my artwork which I need to color correct. They are so tiny I cannot see them for this purpose. Though I searched high and low, the only answer that came back was the preference for TIFF files! Of course not one said anything about how you wouldn't be able to see it so you could work on it!!! Can I save these? Can I save them into a large format high resolution JPG? When I try to do that, it makes the resolution lower.

Thank you!

Also ".tiff" is not the standard file appendix for a tiff file. It should be .tif - where did you get these files from?

Your description is confusing. The only relevant measure of size for a Photoshop file is how many pixels - or as Kevin asks, canvas size and resolution, which defines a pixel size.

TIFF and PSD are the only alternatives if you want to keep full quality of the files and preserve all properties. Jpeg is not an option here. Jpeg compression is destructive, non-reversible and cumulative. Saving to jpeg always results in slight quality loss, more so with every resave.

Resolution is only meaningful in relation to the canvas size. It is expressed as pixels per inch, which means exactly what it says: resolution = pixels / inches. It's a standard equation - if you know any two of them; the third is given.

The size on screen is another matter entirely, depending on the zoom ratio. This relates to how many screen pixels are used to represent each image pixel. At 100% it's 1:1, one image pixel to one physical screen pixel.
