When i try to install fcam, it says "incompatible application package."? What do i do?? By the way, am i supposed to download fcamera or fcam? Which is the real thing? I don't like fcamera...the pictures are not good.

What I'm saying is that if swapped in the N900's sensor, that EF 1200mm focal length lens would act as a 7200mm one, a frightening zoom (yes, you would have to have enough light and shutter speed to actually make use of it, but that's a different story).

As for the usefulness of digiscoping, it all depends on whether you know what you're doing. For example, if you're trying to make a photo of a planet, those monster Canon/Nikon lens (and DSLR image processing algos) fail miserably as they were not made to deal with astronomical imagery, no matter the depth of the wallet, a medium-class telescope and a cheap webcam will win every time at a fraction of a price of the big glass. Now, the cool part is that with fcamera is that we don't need that USB webcam, the wire-jungle, notebook, power banks - all that can be replaced elegantly with a single N900.

There's already a fix in svn but the original point still holds: the compatibility of the raw output is being tested against proprietary windows software rather than open source implementations. I find that funny/sad. I don't expect you to be amused by it, though.

I see no obstructions for open source people to write their own app that reads dngs.....

yes you would use the fraction of its image circle. it is exactly the same than cropping 3mpix image from 30mpix ff sensor.

and I don't buy the winning part. there are multiple pros for large sensors and cons for small sensors in general (noise being the biggest enemy of details, with bigger sensor I get with 4mpix double amount of details compared to N900 only because NR eats the details ..)

fcam-drivers isn't involved in DNG saving at all, so it won't be changed for this fix. Version 1.0.5-2 is just a packaging update on 1.0.5-1 - there's no feature/bug fixes.

-Eddy, one of the FCam developers.
Will this mean I can open the fcam dng's with Photoshop CS2 and the latest camera raw? At the moment it will not recognise the Fcam dng files but other dng file are ok.

That’s only true if sensor pixel sizes are the same (which most of the time aren’t).

In general, yes, but not universally - that’s why I say it depends on what you’re shooting. Back to the planetary planetary imaging I mentioned - the planets are so bright in telescopes that you can shoot videos with those tiny pixels. Noise doesn’t matter as you stack/average the images (and here's the big plus of fcamera/RAW - you can get rid of crappy camera NR !). If you used large DSLR pixels, you’d lose details (exacerbated with the bayer layout) and win nothing on noise. On top of that, with a DSLR you’d move a super-large amount of data when in fact you really need just a few thousand pixels per image.

EDIT: But only so we end the digression - yes, from an image quality aspect bigger sensors are preferred unless you KNOW that your particular subject and lighting conditions do not require it (it would be more precise to say - you need the smallest pixels possible that pack sufficient sensitivity to capture a particular image).

Tested with titan's driver and photoshop CS5 - files are recognized and opened properly.

HDR imaging is new to me, so please excuse stupid question ... When set to HDR camera take different number of pictures -- mostly 2, sometimes 3 and in one case I ended with 4 images. Also, when opened in PS I noticed EV values are sometimes same -- 2-3 times EV +0.00 thus images are almost the same. Can this be due bad light condition (10pm and in pretty dark room)?

Also, just got update message that new "official" drivers are out - 1.0.5-2. Can't find changelog (yet) .

I'm not going to buy CS5 just to access Fcam dng files!!

re HDR
It should give at it;s simplest level 3 images. One exposed for shadows, one exposed for highlights and one normal exposure. The Fcam app will not combine them but the HDR capture app will

That's what I thought, too ... 3 pictures minimum. Hmm :/

It's called dcraw, and there's a bunch of graphical derivatives that use it as the engine.
