Common perception is that GIF sucks in comparison to JPG so you would be crazy as a camera maker to market a GIF digicam even if the pics were better

Most GIF's are 256 color anyway

The GIF format is great for web graphics which have a limited number of colors. Plus it supports transparency, which JPEG doesn't.

It is NOT a format for pictures. While it is an adaptive palette, it is still only 256 colors. Those 256 colors can be any 256 you like, but only 256.

Open up a nice photo in PS (or any other decent image editing program) & convert it to GIF. Let it pick the palette (it will do a good job) & see how bad the picture sucks.

explain "hold up better" and why you think that.

when I shrink it, the pic looks better then when I resize jpgs.

I could be just doing it wrong. I'm not good at editing stuff.

You do realize that when you take a picture with a gif, not only would it take about a minute and half to write a 4.1MP image to a media card, but it would probably also either 1) look like crap or 2) be about 5-10MB per picture.

High color GIF = No.

Besides, PNG is overtaking GIF. The transparency is better and filesize is slightly smaller.

GIF is an old format, and offers relatively poor compression for photographic images. JPEG offers much smaller files, at the expense of some detail.

Most programs only support 256 colour GIF files. The true colour GIF format is poorly supported, so you would not be able to distribute your pictures easily.

If you must have lossless files, then TIFF is supported by most cameras. This could be converted to PNG which is well supported, offers true-colour, is lossless and offers considerably more advanced compression options than GIF.

no they dont, Most if not all do JPEG & TIF, higher end cams do RAW, Canon and Nikons have their own formant for it .raw for canon and .Nef for Nikon, they can be converted to a TIFF useing their programs and then opend in Photoshop or whatever and be saved as a PNG or PSD or whatever you want , I use .NEF -> 16bit.TIF -> .PSD

I use jpg for everyday photos, gif for B&W (so I can actually get solid colors), and png when I'll be doing a lot of compression and messing around with the file.

No cameras support gif or png. There's a reason for it too. Buy 1 $300 35mm SLR body, $5800 worth of lenses, and a $10,000 35mm film scanner and you won't have any problems.

whats the reason cameras don't support PNG?

I only wanted to spend $300-$750 tops for a camera.

I already have the olympus c-4000, but I just feel that it doesn't offer enough for its size. However to be fair, I got it a year ago for something like $340. thats not bad.

I might get the olympus stylus 410 for $300 and use that to take pictures when I'm just hanging out, but it only supports jpg format.

file size, write speed, not widly used until recently & Jpegs work for just about everyone, thoes that need a higher quality image shoot in the RAW format their camera provides

OK, then. Check this one out.

From your own link:

Unless there is a specific need for a lossless true color picture to be viewed on a browser not capable of PNG, true-color GIF should not be used.
