Getting error when trying to open scanned-in file with Photoshop Editor 2020

I'm on macOS Mojave V 10.14.6 and Photoshop Editor 2020 v18 (latest).  I have a huge project ahead of me scanning in all the old negatives from my families lives.  I'm using an Epson V600 Perfection scanner with none of the fancy options turned on, using the Epson Scan 2 software to scan them in. 

 

I'd like to scan the negatives at 4800 dpi, but can't even get a 3200 dpi tiff or jpeg to open in Photoshop Editor.  The 3200 dpi jpeg file size is less than 13MB, the tiff one is very large at 791MB   I have ample memory available (32GB, of which 15.5 GB is in use), but when trying to open the tiff file it says "Could not complete your request because Photoshop Elements does not recognize this type of file".  If I reduce the dpi to 2400, it then opens it.  But 2400 dpi is not really enough for negatives, especially the ones with large family portraits we might want to enlarge. 

 

I don't want to proceed on this large (multi-week) project without being able to scan at the desired dpi for these negatives (don't want to have to do it twice!).  I've googled a lot and can't seem to find any solutions for this particular issue.  

 

I'd REALLY appreciate any help on this.

 

Thanks!

Jill

Correct answer Greg_S.

What is the actual pixel size of the image?  Check here to see the maximum size that can be handled by Elements.  Your scanner's dpi is not the same as the ppi that it outputs to your tif or jpeg file.  And you are not actually increasing the real resolution of the image by scanning at a higher dpi.  The scanner interpolates the "dots" and is merely adding to the size of the file without adding any real detail to the image.

On the mac side Preview would be the application to use open the tif/jpeg files for resaving.

 

A third party equivalent to the windows only Irfanview would be GraphicConverter.

    That’s really good information, Greg. It says Editor can’t handle anything over 30K by 30K and my files were around 8460 x 35300. It was scanning more than it needed to though, vertically, so I figured out how to change the scanning window and have it come in under 30k vertically and editor opened it.

    Thanks so much!

      Can you open the 3200 dpi tiff or jpeg in another program?

      Try Irfanview (free).

      www.irfanview.com

      If this works, save the file(s), and open in PSE subsequently.
