As most of you probably know...

I'm a minority now...

I'd be curious to know what you think of Adobe's .DNG format, it's lossless and contains metadata. Are people other than high end photographers actually using it to good purpose anywhere?

First I'm hearing of that format. Off of the top of my head, is it an open format? Knowing Adobe, I'd guess not. That's what helped spur the creation of the PNG format, IIRC, as licensing issues around GIF cropped up a few years back.

Thanks for your efforts here. I think resolution is worth mentioning as we try to get to "retina display" quality. If I read correctly that's a resolution of about 3k as opposed to 1080 or 1k resolution.

What that means to me as a photog is I have to do all my imaging in camera raw, and archive that for later use. Bye bye 72 dpi Not gonna miss ya. It looks to me like 300 dpi is where the web is going, aka "print" quality. That means lots of space for images. Each image for me is 25 megs. Some pro cameras double that. We have to archive those, then be ready to size down for the web. 100k images are not gonna cut it any larger than a small logo.

Webmaster and photographers are going to fill up the largest drives fast. But as CJ has shown us here, we can put up some beautiful images at a good size for viewing at 400k or less.

I had to look that one up. Based on what I read, I'd think it would mostly be of use to photographers as formats suitable for web use tend to focus primarily on small file size, open standards, and ubiquity.

It might be of use in the print design industry where high resolution images are often needed, but again you run into the issue of ubiquity and support for for CMYK color, which I didn't see mentioned on the Wiki page. The most common file type currently is use is TIF, which pretty much anyone with a compouter can open, and which is lossless when not being used as a container for holding a compressed JPEG.

Interesting. I just recently purchased my first device with a Retina display, a brand spanking new iPod Touch. Gorgeous display. I hadn't really even given a thought to whether some images/sites might be Retina-friendly. I guess that's something I need to look into.

Sheesh, I'd love to see hi-res images on the web, but I don't know how realistic that is in the short term. Technology moves at the speed of greased lightning, but standards & widespread adoption of new technologies can move at a snail's pace. What immediately comes to mind is 1.) Retina displays are expensive, proprietary and don't currently have the lion's share of the market, 2.) Bandwidth is always an issue, and finally 3.) Adoption.

Web designers have long had massive headaches dealing with cross-browser compatibility issues. That has gotten better in recent years as browser standards have improved, only to be replaced with more headaches where interface design for mobile devices is concerned (see responsive web design). Trying to create a design that works elegantly across anything from a widescreen, hi-res 24-nch desktop monitor to a teeny-tiny smartphone screen is only for the bravest of souls (which is why I haven't attempted it myself yet, though I'm thinking about it because I know I have to).

The idea of also having to accommodate resolution independence in addition to all of the above makes me want to throw in the towel and go apply for a job at Mickey D's, heh. ;)

To me it's useless. I have a raw format with metadata, Canon CR2. DNG is about lossless digital negatives with the metadata. Think of it as a camera independent raw format.

But if I wanted a consistent raw format incoming from people with various cameras that might be helpful. Otherwise I just open up the raw in a separate bit of software (sometimes Adobe sometimes the camera raw reader software) then open it in PS.
