Photo AI Tiff Output is greatly reduced in MB size

[Please describe your issue here. Try to include logs (Help → Logging) and add screenshots if necessary.]

I am generally using Photo AI directly (not the plugin) for 250 MB TIFF files. Each time I run the AI processor, the output is generally 52 MG in size even when using the 2x upscale. How can I retain the original TIFF size?

Steps to reproduce issue:

  1. Step 1: Select a TIFF image (typically 250 MB) in Photo AI

  2. Step 2: Allow Photo AI to run the preview with Denoise and Sharpen.

  3. Step 3: Run the Process sometimes with Upscale. Output is typically 52 MB at the same pixel dimension. Image quality looks very good.

Is this a standard Topaz AI output size. If so, why?
Thanks.

Also when you export your image, in the Export Settings under Format are you using the Preserve Input Format or are you selecting TIFF as your option for export?
