Is there? "MiB" means "binary million bytes" and "MB" probably means "decimal million bytes".

296.483 * 1.024 * 1.024 = 310.884958208

So, one version of a file is 222.5MiB, and another version is 111.284MiB. They are both 8 bits/channel/pixel. Does "compare" say the pixels are identical. Does identify say they have the same compression?

snibgo,

Yes, I see how that is correct. I'm a layperson so wasn't aware of that before.

"Compare" doesn't do anything for me. The number of pixels is similar. fmw42 was right in that the image is lacking compression. It becomes uncompressed when working with IM and then needs to be compressed again. fmw42 wrote

"When you start are your TIFFs 24-bit color or 8-bit color (or grayscale)? If you start with 8-bit color and resize that will add more colors and you will get a 24-bit color result. If you want to keep the 8-bit color, then you need add -type palette to your processing command to keep the result at 8-bits color." This makes sense to me however, my supervisor doesn't want me using LZW compression (I personally am not against it at all). Also -type palette didn't get the results I needed.

Below is the verbose. I checked compression and it said none for all of them. Also, why do the IM processed files read as 208036.tif[0] and 208036.tif[1]?

The file contains two images.

I'm getting confused. When you have two images of the same size in one TIFF file, the file size is 222 MiB. When you open one of those images in Photoshop and save just that image in a file, the filesize is 111 MiB, half of what it was with two images.

Is that right?

snibgo,

Yes what you said is true. It is strange, isn't it?

Thank you for all of your help.

What is strange? That your input files contain two images? You haven't said where they came from. How many images would you expect? Perhaps there is a bug in whatever made them.

Snibgo,

I've specified that they were processed in Capture One 11 from IIQ RAWs into TIFF 8 bit Uncompressed Adobe RGB (1998) 300ppi Scale Fixed 100%.

And it wouldn't surprise me as Phase One/Capture One is buggy as stuff and they take steps to make everything propriety on arbitrary grounds.

I tried it before with LZW compression and it seemed to get me closer to the results my employer needs. I can try that again and send you the documentation of that as well. Also, I checked and in the source folder there are only 3 files but after typing identify it is saying there are 6 images with the same [0][1] scheme. These images haven't been changed by IM in any way.

You can see these are very different sizes. I suspect the second is a thumbnail version of the first. Perhaps you resize this file (containing two images), so both images end up about the same size. But the second probably looks horrible because it has been enlarged so much.

snibgo,

That makes sense. I had the same idea. I looked and didn't see the "Create thumbnails on save" box checked but can have another go at it. I'll try a few things and show you the documentation later.

snibgo,

This may be premature but I think you are right. In Capture One under the Process Recipe tool and under "Options" "Uncompressed, LZW, Zip, No Thumbnail, Tile Dimensions" are selectable. I had " Uncompressed" selected but after selecting "Uncompressed, No Thumbnail" it no longer identifies two images in one file e.g [0] [1] but as one. One small change in settings needed to be done.

I apologize for all the trouble and would like to thank fmw42 for the help as well. I did the resizing with IM and no longer had the file read size discrepancies between the finder and Photoshop.

Thank you all.
