Re: Mirrorless DSLR for bookscanning

Slightly off-topic, but spreads can be used for shooting as well, there is a gphoto2 driver available (that I revamped this week) that uses libgphoto2 under the hood.

Re: Camera dual triggering

1. Try to reset the configuration on your cameras and set them both to the settings described here: https://github.com/markvdb/diybookscanner/blob/master/misc/settings.md Do not configure anything in the CHDK menus. Make sure you run CHDK 1.30 (unstable). 2. Does remote capturing ('remoteshoot' comm...

Re: Camera dual triggering

Ok, if the time between those shots is always the same, then I'm almost certain that you accidentally have enabled the `intervaltrigger` plugin. Just remove that from the configuration and you should be good. About the flash, make sure that your cameras are set to 'manual' shooting mode (there's usu...

Re: Camera dual triggering

Bart, your problem can bedue to you running spreads with the 'hidtrigger' plugin on a machine with another HID device attached in addition to the keypedal. The plugin indiscriminately triggers a capture for any action on any USB HID device, i.e. if you have your keypedal and a USB mouse attached, it...

Re: Fastest computer build for Scan Tailor?

Currently ScanTailor only runs on a single thread. To get the best performance, you best use a script to split your ScanTailor projects into multiple configuration files and launch multiple processes to process these. This is the way spreads does it, but I think there's also an AutoHotKey script som...

Re: Newbie with Spreadpi and Spreads Questions

Leo, this looks like a bug in the path-handling code. It seems something goes wrong while processing relative paths. Could you please try again with an absolute path? I will look into this!

Re: SpreadPi vs Raspbian

The main reason for the current approach of bootstrapping our own image instead of working from the standard Raspbian distribution is to keep the image size as low as possible to make room on the card for scanned images. It is also primarily intended as a "plug in and forget" kind of appliance, user...

Re: Newbie with Spreadpi and Spreads Questions

Leo, can you confirm that the images were not rotated before and have valid EXIF orientation tags? You can also send me some sample images from your project and I can try to reproduce locally. If this is the case, here is a minimal example configuration and a command-line that I used: plugins: - aut...

Re: Newbie with Spreadpi and Spreads Questions

First of all, sorry for answering so late! The GUI can currently not be used for post-processing alone, it has to be used for the whole capture->process->output chain. It is very easy to do post-processing on the commandline, though, just run "spread process --help" to see all available options, the...

Re: Newbie with Spreadpi and Spreads Questions

I'm really sorry about the sizing issues, I've developed mosty with a 1680x1050 display, a Nexus 7 tablet and a Nexus 4 phone, so resolutions outside of these might be a bit wonky. Please file an issue on GitHub so I won't forget about it! The spreads documentation is currently also woefully out of ...
