And it's packaged as a portable app so you use it on the go. Both the 32-bit and 64-bit versions of the app are packaged together and the right one is automatically used for best performance. It's packaged in Format so it can easily integrate with the Platform. And it's open source and completely free.

Revision 2: Fixes a category error when used with the Platform.

ScreenshotRawTherapee boasts a wide range of features letting you get the most from your raw photos including modern and traditional demosaicing algorithms, advanced color handling, enhanced exposure and tonality tools, multiple denoising methods, and several tools to enhance details. It uses multi-thread algorithms for high performance and works best on 64-bit machines, though it should work fine on most 32-bit machines with proper memory management. Batch processing is also available. A wide variety of digital cameras are supported including almost all DSLRs and even some medium format bodies. The interface is configurable into various layouts including: multiple tabs, single tab with filmstrip, vertical tab with filmstrip. RawTherapee (as well as the RawTherapee Portable launcher and installer) is free and open source, meaning you can use it free of charge, wherever you like on whatever hardware you like, as long as you abide by the GPL license.

Nice addition, it's a good app - one thing, it shows up in Platform under Utilities, it should be categorized in Graphics and Pictures.

I made this half-pony, half-monkey monster to please you.

Fixed in rev 2. Sorry about that.

I was looking forward to see this release in pa, thanks guys!

Thanks for making RT part of Portable Apps. I've been using RT for a number of years now and it is great.
Some additional info:
RT uses a lot of memory! It needs 2G of ram, when using it close unnecessary windows. This is critical with 32 bit machines. Read Maximizing Memory Efficiency referenced above, it will significantly reduce crashes.
RT can also be used with JPG images with reduced functionality.

Did you miss the fact that this app has 32-bit and 64-bit versions combined and will use the correct one on each PC? That way you're not stuck with only the 64-bit version when you happen to be on a 32-bit machine. And you can take advantage of the 64-bit version when you are on a 64-bit machine. Smile

Hopefully we'll see more 64Bit versions of Portable Applications.

There are multiple 64-bit portable apps already. I laid out our policy on 64-bit portable apps about 2 years ago. We have specific instances where it makes sense to do a 'dual mode' portable app with both versions within. Specifically, [1] when required (like defraggers and other system utililties that require the appropriate version on each PC. JkDefrag for example), [2] when there is a worthwhile speed improvement to offset the size increase in the portable app (7-Zip and PeaZip both do this for just such a reason) and [3] when the 64-bit version adds additional features/functionality (as would apply with RawTherapee or AkelPad which can open much larger files). So, we have a bunch of apps that fit this criteria. Most other apps, the 64-bit version (when there is one) makes no difference at all, so we stick to the 32-bit version only, which runs fine on 64-bit Windows.

Basically, you've been using 32-bit/64-bit dual mode apps for 2 years without even knowing it, because we have the apps do all the work automatically for you.

I like the default design of RawTherapee better than the one the portable version has, but I don't know how to change it

don't mind my english, I'm german

We made no changes to the look and feel for the portable package. It's just the defaults. And the portable and local one look the same on my Windows 7 PC.
