Hello! I would like 70mmx100ft of Foto 100. Shipping would be to the UK.

Again it doesn't quite work like that for scanners as the application is so much different but of course fundamental physics applies. In the scanner we have the luxury of a lens being 100% fixed in working distance and aperture so it only needs to be designed for exactly one use case (which also...

There are major trade-offs between linear and area sensors, and in this application an area sensor ultimately made far more sense due to the constraints linear sensors impose on the optics and backlight system. A linear sensor operates at extremely high line rates, meaning the integration time...

Hi all, sorry I've been quiet on this. It's been quite an eventful 6 months or so, we hit a few bits of bad luck that almost sank the project but the end is in sight now. I will have some news in the coming weeks.

Of course! I've been a long time lurker from way back in the APUG days. In fact I arrived here because an extremely generous person (who I can't remember the name of) gifted me an Nikon F3 on the condition of a token donation to APUG when I was a poor student around 12 years ago. Yes we get a...

Hi all, I’m George, the owner, founder, and sole engineer at Soke. The topic of image sensors is a bit of a contentious one that falls into the overall film vs digital debate — i.e. why shoot film and then just scan it with your digital camera? There are many, many dimensions to the trade-offs...

Would you ship to Germany? If so how much would it cost? FedEx or UPS would be preferable.

Thank you all, these responses have been fantastic. I got one of the Vlad's targets and messaged Ilford about their pre exposed strips.

Ahh yes, I have access again now. Thanks everyone!

Hi all, does anyone know if Ilford can provide reference film? First, I'm looking for films pre-exposed with a gradient in know exposure values. Second, if there are any high resolution, resolution measurement targets, that would be awesome! I've developed a new film scanner and would like to...

They never load for me and external website status checkers show it as down for all. Is this the case? Anyone know what's happening?

I'm not sure yet. The sensors that are available have a BW channel with some IR sensitivity however I'm not sure if that'll work. There are few sensors on the market and the ones that are are limited. I've been doing my tests with a roll of film that's just been sitting on my desk, I give it a...

A 10m scan time would be for 36 frames. This current prototype (2000dpi) does 36 frames in 1m 45s. Thank you!

The new stepper motor has fixed the issue. I now have a fully working 2000 dpi film scanner. Please follow the link below for the full resolution image, looks real nice. Google Drive Image The new design is in progress. I have a lens coming to me from Schneider-Kreuznach that looks like a...

So I have verified the stepper motor non linearity is the issue. I calculate ~8.91 pixels pass per stepper motor step of 1.8 degrees, I have 1/32nd microstepping enabled. The average spacing between the vertical artefacts in the image are on average 8.5 pixels apart. A new stepper motor is on...
