I have a large number of files to convert from jpg to Tiff format.

So I first tested using Photoshop Elements (2021) and Adobe Bridge. My question is with regards to these two fields:

 

Document Type: TIFF image

Package: Adobe Photoshop Elements 19.0 (Macintosh)

File Size: 19.44 MB

Dimensions : 3005 x 2259

Dimensions (in inches) 41.7" x 31.4"

Resolution 72 ppi

Bit Depth: 8

Color Mode: RGB

Colour Profile sRGB IEC61966-2.1

----------------------------------------------

Document Type : TIFF image

Package: Adobe Bridge 2022 (Macintosh)

File Size: 19.45 MB

Dimensions : 3005 x 2259

Dimensions (in inches) 10.0" x 7.5"

Resolution 300 ppi

Bit Depth: 8

Color Mode: RGB

Colour Profile sRGB IEC61966-2.1

 

 

The question is, how come one says:

10.0" x 7.5" at 300 ppi

and the other says

41.7" x 31.4" at 72 ppi

 

for the same document?

If someone can just explain what this means. Thanks.

Simple.

You have a digital file which is made of pixels.

Do the math:

- 10 in x 300 pixels per inch is 3000 pixels

- 21.7 in x 71 pixels per inch is also 3000 pixels.

 

The only thing which is important is the pixels count. You can print or display as big as you want from the same image, that does not change the pixels count and the details level in your file. The so-called 'ppi' is only a tag telling you the physical size you'll get in two different cases:

- you want to print

- you want to display on a screen.

 

The 300 ppi resolution means you'll get a very detailed 4 x 6 print.

For big prints A4, A3 and more, 200 ppi will be good enough at normal viewing distance.

The 72 ppi resolution was good for very old displays with about 72 pixels (photo sites) per inch. Today's screen are rather in the 90 to 200 ppi, so that indication does not help much.

. . .  and in case you are not familiar with it, in the Elements Editor, you can use the File>Process Multiple Files menu command to convert the files in batches.

Thanks, that is what I have been using.

It is interesting that when I used Adobe Bridge 2022 for batch conversions for sets containing over a hundred files, it crashed each time, just after four sets. where else the batch conversion in Photoshop Element carried on fine.
