Question

Large files slowing down PC...

I have some large TIF files from scanned film. The TIFs are 150 MB and their associated PSDs are 500 MB.

I'm running into issues with Photoshop slowing down and doing some unexpected and inconsistent things to the point where it's getting impractical to deal with.

The machine is Windows 10 with 8 GB of RAM, but the machine appears to be having performance issues that show up in other areas - not just Photoshop. I've tried to address those issues but the culprit hasn't been found. In the meantime I restart my PC frequently - which helps for awhile.

Is there any practical way to reduce the file sizes? The intended output is going to be inkjet prints 16 x 20 and smaller.

The files in question are grayscale but I'll be doing color images soon.

    I would think 16GB and temp and scratch space on SSD Photoshop will perform good. More RAM will not hurt, but before springing for more RAM. If Scratch and Temp Space is not on SSD spring for SSD.  I have 40GB a Ram I have seen Photoshop use all of it however the is the exception not the norm.  Photoshop normal RAM usage is less than 10GB .  Photoshop Uses scratch space always.

    Adding to what JJ said: If you can afford to, get more RAM. 8 MB is a little paltry as Photoshop loves RAM (actually, Windows loves RAM too); as much as you can throw at it.

    You can also try taking a look at your SysTray (the notification area in the lower right). Anything that's not essential to the task at hand shouldn't be running as it's just wasting resources (like RAM). Try right-clicking and closing anything that's running there. You can also usually prevent them from starting by right-clicking the icon in the SysTray and choosing not to run on startup (any company worth their salt should provide this option) or using Ctrl + Shift + Esc to launch Task Manager > (click the "More details" link if you don't have Task Manager in its more detailed form) > Startup tab > right-click anything that you don't want to launch when you boot Windows > Disable. (Tip: Don't disable anything Adobe-related as some of it is needed for CC.)

    What resolution do you want to print at?

    16X20 at 300dip would be a canvas size 4800px by 6000px =  28,800,000 28.8MP around 173MB 16bit color 84.4MB 8bit color uncompressed.

    If you print at 200dpi you could reduce the canvas size 3200x4000 12.8MP around  77MB 16bit color  38.4MB 8bit color uncompressed.

    if the scanner Produces Tiff file that are 150MB and the tiff file are compressed.  Your canvas size is much larger than it need be..

    How many MP do you have for you image? What the canvas size in pixels??

    What resolution do you want to print at?

    300

    Most of the prints will be in the 8 x 12 range; some 10 x 16. I mentioned 16 x 20 because that's the largest I'd make.

    What the canvas size in pixels?

    6000 x 9000

    How many MP do you have for you image?

    Is that the 6000 x 9000? If yes, 54MP.

    I always appreciate your help, JJMack!

    Your canvas size is much larger than it need be..

    So, to reduce the file size is all I need to do: go to Image > Canvas size and change it there?
