Re: Stereo Data Maker

For example, there are a number of Powershot A630's on eBay that are selling/have sold for around a hundred bucks each.

Re: Stereo Data Maker

That is the primary feature, but it's good for a lot more. I mean, there's nothing wrong with cracking open a few cameras and soldering to the switch contacts, but SDM will give you readouts of all important camera parameters, like zoom, and give you raw format support, and timers, and all kinds of ...

Re: Examples from my postprocessor software

I don't know if it was Daniel or bkrpr Actually, I think we've both said it at one time or another. I mentioned it here: http://www.instructables.com/id/SWV8JKCFTM72X5S/ and in the comments somewhere. One funny thing is that all cameras worldwide use this standard, but while in Russia, I discovered...

Re: Hardware buildup for a Sliding Glass platen scanner.

This is great, thanks! I asked Rob to do something about the way the pics are displayed. It's awesome to have such huge pictures, so I hope we'll be able to see them all.

Re: Examples from my postprocessor software

Rob, thanks for the pointer to Otsu's method. That's a pretty sweet method of thresholding.

To what degree is your processing resolution-independent? Don't you have to choose a radius for erosion and dilation to work?

Re: Examples from my postprocessor software

Ack, sorry. I forgot that you had different cameras. Yeah, 4.0 is definitely a better bet. ;) One thing they get right on the Canon compacts is that they give you a small section of the screen with 100% magnification, so you can do manual focusing pretty easily. Still not nearly as nice as a rangefi...

Re: Examples from my postprocessor software

with CHDK (http://chdk.wikia.com/), our compact Canons have all the features of SLRs (and sometimes more). Spamsickle, while you're pretty much right about metering, I'd like to mention a few things here. The reason that they're grey is because Rob's camera is set to auto-expose with a center weight...
