In Photoshop CC, why is the image size given meaningless?

On my site, I can't upload tiffs over 64meg.  After processing in Topaz, some are much bigger and uncompressed.  Sometimes I have an image that is a little bigger, eg. 68.  I may reduce a dimension and it says 58meg.  When I save and compress again, it may come out much bigger, like 80meg, which makes no sense to me.

Now I have some big ones, over 100 meg.  In image size I reduce the dimensions and it says 58meg.  I save and compress and I have to go over all again when I see now it is 80meg. What it says in image size has no relation to what it is saved.

How much RAM and spare hard disk capacity do you have?

Why do you need such large image files?

Hi!

 

Are you referring to the number of the image size panel?

If so, that number is not telling you your saved file size. It's a shortcut reference that gives you the calculated digital image size of the image based off the pixel dimensions and your workspace color channels. More information can be found here:

Photoshop image size and resolution (adobe.com)

 

Can you show us an example of a file you are currently savign to tiff format, and what options are you selecting while saving. screen shots will be very helpful here in your step by step description.

 

Thanks!

 

-Chris

This is the screen I was using to adjust and resample tiffs to a smaller size.  Usually if it indicates, after adjusting size measurements so that it is under 64meg then it does appear to have that size in Bridge after saving.  If there was some way to have an action automatically adjust the measurements with the ratio remaining the same, to arrive at a certain files size, eg <64meg, that would be ideal.

 

Asked why such large files, the answer is that with a camera that produces large files, eg ~60meg, they are large to start with.  After using Topaz on ones that were cropped only slightly, they may become over 100meg.  Do I need them that large, not necessarily.  It depends on what a client might want.  But am I going to shrink my files, after using a camera with such great detail, so that I would have to lose all the time and processing spent, and start over again - no. 

16G RAM. I had ~180G of space free on the internal D drive where I have the cache, but since posting initially I went on a trip and downloaded a lot of files that are on it till I prepare them for permanent storage on the external drive which is 12 T and has ~4T free.
