DailyDirt: Digital Photography Magic (aka Photoshopping)

from the urls-we-dig-up dept

Altering a few pixels here and there in a digital photo can have remarkable effects. Sometimes the result is unexpected and hilarious, but sometimes it's simply amazing what can be done to photos. Perhaps you've used software (eg. photoshop) to remove "red eye" from your favorite selfies, but there are some even more advanced algorithms that can make your photos look much better... than they otherwise would. After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    Call It A “Photomanip”

    Given that alternative tools like GIMP and Krita are getting more and more popular, let us help put Adobe out of their trademark-losing misery by using a more generic term for what these tools do.

    They do “photomanipulation”. The product of same is often described as a “photomanip”, plural “photomanips”.

    Will these algorithms be released to the public so that they can freely incorporated into any image program? Or will they be exclusively used in stand-alone programs and Photoshop?

    I don't consider myself an artist, but I like to occasionally try my hand at image editing, and it's always disappointed me that the only two practical options for most advanced editing are Photoshop (ridiculously expensive and reportedly confusing to use) and GIMP (free, but confusing to use).

    A couple years ago I started a project to produce a digital version of a copy protection map (black printing on dark blue paper) included with an old C64 game. It didn't scan very well and it was recommended that I use GIMP to improve the scans. I tried, but couldn't get anything approaching a usable image out of it. I'm sure it's capable of doing what I needed, but I couldn't figure out how to do it.

    I ended up processing the images in Irfanview, which is much more intuitive (if more limited) and then tracing them in Ultimate Paint, which is the most intuitive drawing program that I've yet found for Windows.

    I don't have Photoshop (nope, not even a pirated copy) and trying to use the drawing tools in GIMP was a pain in the ass.

    Re:

    Photoshop, like most quality image manipulation packages, is specialist software.

    Unlike many software packages, the difference is that Photoshop has been a kind of industry standard in a space that has a lot of interest - everything from 'simple' filter effects on photos by budding photographers to multi-layered animated matte paintings for use in feature films all get done in the package.

    The price tag in part supports research and development which provides features that push the state of the art which sells more licences. Sure, often what is researched ends up patented, but I find it hard to begrudge them that.

    The great part is, for its ubiquity ("Ah, bet that's a 'shop" - it's so common we don't even say the full product name!), there is a wealth of information available on the concepts involved, and how-tos for learning how to get stuff done. And, with some exceptions, that knowledge remains constant from package to package.

    Re: Call It A “Photomanip”

    I prefer sticking with using "photoshop" as a generic verb. If enough people do this for long enough (and I think we're pretty close to it right not), then Adobe will lose the trademark on it -- like what happened with "zipper".

    De-bluring photos

    I have been using Gimp to be-blur photos for years now, following a procedure I found on the web. It works pretty well, depending. The more you know about the motion of the camera that resulted in the blur, the more accurate the blur removal is. I love the idea of using the other camera to track the motion!

    Reflection removal

    That could work great for all those vampire films...
