File size limit in PhotoLab 5?

[RebDovid2]

The recent death of an elderly relative prompted me to begin scanning old family photographs. I then want to edit selected images. Either because of the file size produced by the scans--c. 150MB--or some other reason, I'm finding that PL 5 regularly freezes I try to batch export edited tiffs to jpegs. I've submitted a technical support request to DxO but thought that someone here might be able to help.

I'm running PhotoLab 5 Elite (although I think the Elite aspect irrelevant) on a Dell XPS 8930, Windows 10, 64-bit, with a 3.20 gigahertz Intel Core i7-8700 CPU, 32GB of RAM, and an NVIDIA GeForce GTX 1050 Ti GPU. Since Deep Prime doesn't apply to the scanned images, I think the choice between CPU, GPU, or Auto within settings is irrelevant. Nevertheless, I've tried both without seeing a difference.

The scanned images are produced by an Epson V300 scanner using the current professional version of VueScan. For quality reasons, I'm scanning to tiffs with two passes and no compression. The resulting files are c. 150MB, which I suspect may be the problem.

Does anyone know whether there's a limit on the size of files that PL 5 can handle for export either generally or as a function of my hardware configuration?

If it makes sense to try smaller file sizes, do people have thoughts regarding getting there via VueScan settings or resizing the scanned images? With VueScan, I can reduce file size my going from two passes to one, via compression, or both. For resizing images after scanning with VueScan, I'd need suggestions as to an appropriate program.

TIA

Using that flatbed scanner I am assuming you are scanning prints. 150mb per scan is way, way, way overkill. Just wasted storage space. You definitely should be scanning at a lower resolution. Are you saving to uncompressed TIFF files or JPEG files? I would expect that JPEG files of less than 5mb would be sufficient in most cases. What size prints?

Yes, I'm scanning color prints. My plan, which indeed may be overkill, had been to scan to tiffs, cull and do selective editing in PL 5, then export to high quality jpegs. Only in rare cases would I retain the tiff "original". My quite possibly mistaken idea was to get as much detail as reasonably possible from the scan. Reading the VueScan manual suggested two passes without compression. If the PL export problem is file size, what do you suggest as scanning parameters?

Not sure what is causing your problem.

I don't normally used Photolab 5 for batch conversions.

As an experiment, I took about a half dozen 16 bit TIFFs created from Canon R5 ,CR3 raws. The typically run around 262MB each. Batch converting them to JPEGS worked just fine.

Separately, I created a 2X (linear) upscale. still a 16 bit TIFF, using Topaz Gigapixel. (16384 X 1092). About 1GB ins file size. PL5 opened that OK.

Producing the largest file Gigapixel allowed (32000 X 21333 pixels) gave a 4GB file. PL5 wouldn't open that.

My PC has 64GB of RAM, but I doubt that matters.

I scanned some negatives a while back that produced some large TIFF files. I used Photoshop to work on them afterward rather than PL, because at that time Ps offered better tools,

Actually, I recall that it was not PL that I had but OpticsPro. I have not tried editing large TIFF files since, so my experience may not be applicable.

You can only get the detail that is actually in the prints. Scanning at higher and higher resolutions won't get you more detail than what the print has. It will just get you humongous files. You didn't say what size prints you are scanning. For example, for a 4x6 print then 1200x1800 would be more than sufficient. For an 8x10 then 2400x3000 would be more than sufficient. Actually, say, 1000x1500 and 2000x2500 should be more than sufficient.
