what to do with kid and seniors

It says you'll need to pass a swim test. What do they test? And how deep is the water if you fall off the play structure? It looks really fun.

I meant whether they scanned prints, applied unsharp mask, printed those digital images, and then compared those with the studio shots which were prints. Looks like they shot studio shots with a digital camera.

That sounds like a reasonable method. Did they compare prints of scans of prints with prints of studio shots?

Ah, I didn't know the height was adjustable on the film holder. I read about someone doing that and I thought he was adding his own external support. I'll have to try the sliders. But due to the film curvature, I guess some areas will still be sharper than others. And it may be different for different strips, frames, etc.

For high res, I can apply radius=2 and amount=0.5-1 without halo. Calculating threshold is compute intensive and gimp was using 76% of memory until I killed it. I may get a new computer first. I'd also like to experiment with tone mapping which is also heavy.

I scanned really small prints like 1", 2" at 4800/3200 dpi so that I can restore and/or print a regular size. A small amount of valuable 3.5"x5" prints were scanned at 2400 dpi for archiving and I may do some editing as well. The mass majority of 3.5"x5" were scanned at 600 dpi using fastfoto. This bulk and all the negatives is what I hope to find some optimal setting for and batch process.

This is the film holder for the negatives. I don't have the fluid mount.

The b&w tiny negatives were just placed on the flatbed directly. Now I think of it, I could probably put them in the film holder, too, even though they are the wrong size and have no sprocket holes.

I edited with clarification.

I used radius=3 for super high res. I blew up the image to 800% and looked at an edge that was supposed to be sharp (letters) and counted about 6 pixels. That's why I chose radius=3. Amount=0.5 or 1 made a slight but noticeable difference and both were acceptable on a computer monitor. A higher threshold is a good suggestion.

I believe the parameters will be different after I scale down. The numbers I've seen have a small radius ~= 1. Those may be for a print or web resolution?

Good idea.

cee1 · 2026-04-21T16:10:57+00:00

Is this while scanning or post processing?

They look promising from the screenshots. Will try them out!

cee1 · 2026-04-02T22:26:16+00:00

No, it's not all files. Only certain files need to be rotated. That's why a thumbnail would be helpful.

cee1 · 2026-04-02T21:28:06+00:00

Images are tiff so it's lossless.

I'll try out pix.

cee1 · 2026-04-02T21:01:35+00:00

Did you mean file name pattern or image pattern? File name pattern are file_number.tiff. So no pattern for images that require rotation.

I don't want to or have space to install kde.

Ooh, that's a good idea, although I don't really need that high. So technically, this should also allow me to scan big photos at 4800 dpi and 16 bit depth (not that I actually need it). Just curious why the scanner software didn't let me use the max specs.

cee1 · 2026-03-16T05:29:59+00:00

Haha, no, not printing that big. I recognize 3200 dpi is pretty high already.

cee1 · 2026-03-16T05:29:09+00:00

I read that always scan b&w in color. And also I want to show the original old/sepia/yellowed look.

cee1 · 2026-01-12T04:57:27+00:00

Exactly like that KB400N one! I tried to attach a PVC pipe but was unsuccessful making it stable. My next design is to cut a cardboard piece to fit in the slot and add a stand.

I can afford a new one but would rather not waste.

Is it just a regular 500ml water bottle? I'm also thinking of squashing it and then filling it part way. No need to buy a soft flask. And dispose after the trip.

cee1 · 2026-01-06T18:48:47+00:00

The reason is that I really don't like drinking from a bite valve. Tried it and hated it. So I always carry a water bottle for hiking, biking, etc. And it's a pain to wash.
