enblend/enfuse
 

Enfuse/enblend (http://enblend.sourceforge.net/) does focus stacking (exposure stacking also). It's a package available on Fedora so I assume also on others and its source is available so it could be compiled for the N900 I suppose. Despite its rather simplistic front page, it is very powerful and is used by Hugin for seamless panorama blending and HDR.

Photoshop, I'm viewing them in photoshop right now.

Adobe Lightroom and Photoshop should both be able to read it. If you are using the latest Adobe software, use the 2003 development process instead of the 2010. This only applies to Lightroom and Adobe Camera RAW.

tracker is open source project so you can help improve it instead of blame nokia.

My opinion is that a video recording application should send suspend and resume messages to background apps, such as the tracker.

Re: FCam - a new camera API for the N900
 

The biggest issue with snapshot speed is due to low-level driver issues - there's about a 700ms lag when switching from viewfinder to full-res capture. Once we're in full-res, it can be streamed at 10fps just fine (until you run out of memory a few seconds later), but changing resolutions is slow.

Unfortunately, fixing that is quite painful, since we'd either have to backport driver code from the current TI/Nokia development branch of the omap3 camera drivers, which is aimed at much newer kernels (but apparently reduce the lag to around 200ms) or do the coding ourselves, which is a very big job.

Thank you. Unfortunately, it is not the tracker source code that has to be fixed here, but the Maemo5 policy of aggressively indexing media data. Disabling this indexing will unfortunately break a few apps, such as Media Player and the Gallery. Leaving it on slows the system down to a crawl. Personally, I would be much happier if Tracker never existed.

Don't change resolutions. I'm capturing 25 fps @ 1280x720 and I'm just decimating with NEON routines to 640x360 for the viewfinder.

Re: FCam - a new camera API for the N900
 

daperl,

While that works fine for lower resolutions, I don't think it's really feasible for full resolution RAW. 5 MP frames mean you can't run faster than 10 fps, which is a bit too slow for the viewfinder. Plus, downsampling/demosaicking that takes just about 70 ms or so, leaving essentially no CPU for anything else.

I have access to neither nor a platform to run them on.
