You've managed to acquire a good theoretical understanding of Bayer while completely missing the crucial bit that you neither need nor want four adjacent photo sites per output image pixel. (A miracle of modern education.) In real cameras, each pixel gets color info that it's missing by interpolating from its neighbors. http://www.dpreview.com/learn/?/Glossary/Camera_System/Color_Filter_Array_01.htm Before you try to argue this point again, find one camera that works the way you suggest, or one website that explains that Bayer cameras have 4 photo sites per output pixel. Otherwise, don't confuse people who haven't learned not to listen to you yet. As an aside, the reason you don't want to have four adjacent Bayer'd CCD cells per output pixel is that the decreased CCD size would result in more noise, canceling out the benefit you would get from slightly better color resolution. The Foveon chips do have four photo sites per pixel, allowing true color detection, but they're stacked, not adjacent. As a side note, what could be interesting is if you could disable or remove the color mask to get 4 times the resolution on B/W pictures. Kodak used to offer one of their DSLRs with and without the color filter. The DCS760 was color, the DCS760M was B/W, lacking the filter. But both output the same 3032 x 2008 file (gee, looks awfully close to the resolution of the CCD, doesn't it?) and the somewhat increased luminance resolution in the b/w wasn't interesting enough for photographers to buy enough. Kodak doesn't offer them anymore.

Re: recommendation for digital camera -= Shameless Nikon plug
I am using Nikon 4300 with linux and I am able to access it as mass storage without any problem. I just have to mount the camera as usb mass storage and copy the image files to my hdd. If any body is interested in having more info, kindly let me know. Yeah, Me! I have a 5700 and will eventually be using it with Linux. But I sort of figured I would end up running the Nikon package under Windows via VMware under Linux. Getting Windows out of the picture completely is a good idea. What you're doing wouldn't get me any of the features of the Nikon software, though (not that I'm *using* any of them yet, mind you, but...) - for that, I'd need the Nikon software to run directly under Linux?. I'm sure my 5700 will hook up the same way as the 4300... maybe you could post the mount command you're using. Did you have to load anything special as far as USB drivers goes, in order to support the camera? Any information I get, I will capture in a file for Future Use... Doesn't this model and many others by Nikon suffer from low light focusing problems? They lack a low-light focusing lamp, Canan doesn't. That is a problem which is very annoying in low light. I haven't noticed that, but I have noticed the autofocus going nuts when I get up close to a tree with light shining through the leaves; it can't decide what to focus on. I've been forced to turn on the manual focus under such circumsatances. Also, it goes wacky when it tries to resolve something against a plain white background, and I've been forced to troll all the way to the bottom of the white correction menus to try to rearrange its attitude. But I'm always getting into performance corners with everything and then demanding too much, and Nikon support will probably fix my problem anyway when I get around to bugging them about it...

Just out of curiosity, what does that SW offer? Well, there are several packages, one of which is always bundled with the camera and the others for sale separately. The Nikon website is a better source of info than I am, actually. But the direct camera support package provides USB detection, automatic downloading, a bunch of cosmetic viewer features... The buy-up packages provide image correction and editing, I think. (I haven't loaded it yet...). Some of those things are built into Windoze XP, I think (I'm not, and never will be, upgraded beyond Win 98), so the Nikon software for older versions of Windoze provides whatever the older versions don't have... The real benefit to having the Windoze apps (Nikon or not) to support the camera is in being able to load camera (or film scanner) images directly into something like Photoshop without having to go through any JPEG or other compression, so that you can manipulate raw images.

In that case I would also suggest you avoid anything Sony.

I am looking at linux support for coolpix 4500, and it seems to exist (haven't had a chance to test yet, its not mine). Nikon seems to support both mass storage and ptp on their cameras. They do on some of their cameras, at least, according to the website you mention below (interesting site, btw...). For some more information have a look http://www.teaser.fr/~hfiguiere/linux/digicam.html Canon may be a bit more troublesome, then nikon.

I played around with the coolpix 4500 we have in our lab in uni. It works both as a usb-storage device and ptp which gives some more capabilities (you need to chose the active method in the camera's menus). As a usb storage device the camera works like a disk-on-key device. hotplug loads the modules for me (usb-storage and scsi support) and autofs mounts the device. I don't remember what formating the camera uses but you can mount it using one of mount -t vfat /dev/sda /mnt mount -t vfat /dev/sda1 /mnt That is assuming that it will be the first scsi disk (if you don't have another disk on key connected or similar). It is then accessible as a regular disk.. For ptp you need gphoto (www.gphoto.org) and possible some gui above it. If you work with jpeg then you have no problem from that point, just open it in gimp. Nikon's raw format is called nef.

I suppose this has wandered far enough OT from Linux that I can weigh in on it... After using Nikon's website/email support, I will not buy anything else. I bought a dead (as it turned out) Nikon film scanner at a swap meet a couple of years back, plugged it into Windoze, and started in on it. I found every piece of documentation that was supposed to come with the unit on-line. Nikon's support team helped me troubleshoot it, and when their front-line support group couldn't figure it out they quickly transferred me to their specialists who diagnosed a blown SCSI terminator fuse and assisted me in disassembling and repairing the unit. They answered my emails within 2 hours *even on weekends*. They were so efficient that I *never had to make a phone call*. I ended up paying $75.00 for a working $1200 film scanner. After getting that kind of support from Nikon on one of their products that wasn't on warranty and wasn't even bought from one of their dealers, I didn't even bother looking at other cameras when I went to buy a digital camera, because I *know* I'm going to get into software and interface trouble with it just like I do with everything else, and at least with Nikon I know I won't end up having to deal with a third-world something with a third-grade education who only speaks Fungoolistani and can't wait to get rid of me as soon as my question isn't in its hotline cookbook. When it comes to computerized electronics, I'll even give up some performance or features to get support. (What good are the performance and features if you can't get the @#$%^*! thing working??) (P.S.: If anyone knows anything about Linux support for Nikon, please point me at it; I'll probably need it eventually...) (N.B.: I will, for identically converse reasons relating to support, NEVER buy ANYTHING from Fuji EVER again - not even so much as a roll of film. And I hope somebody from both Nikon and Fuji is reading this.) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

(N.B.: I will, for identically converse reasons relating to support, NEVER buy ANYTHING from Fuji EVER again - not even so much as a roll of film. And I hope somebody from both Nikon and Fuji is reading this.) In that case I would also suggest you avoid anything Sony. I've never seen worse customer support (and that even for very high end equipment company customers, not just the small end user), and when they do bother making a proper piece of hardware they seriously cripple it with their copyright paranoia (see NetMD for example). As for nikon, I am using a film camera but very happy with it. High quality hardware and glass. For digital, cannon seem to be a bit ahead now in terms of hardware (cmos vs. ccd). I am looking at linux support for coolpix 4500, and it seems to exist (haven't had a chance to test yet, its not mine). Nikon seems to support both mass storage and ptp on their cameras. For some more information have a look http://www.teaser.fr/~hfiguiere/linux/digicam.html Canon may be a bit more troublesome, then nikon. You should look for a camera with both usb-storage support (easiest way to download pictures) and ptp support which will give you access to some more advanced camera features. I am not sure if it will allow you to access all the features of the camera from linux (some of the high end cameras are customizable and may require dedicated software). Also look at the gphoto site to see what they support to be sure www.gphoto.org -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
