Light Compressor lets you easily combine multiple exposures into striking HDR images. Simply load up any number of images and Light Compressor will combine (and align if necessary) the images for you allowing you to tweak the curves, tone mapping, and saturation.

A must-have companion for anyone who shoots bracketed images, or people wanting to give individual images that HDR look through the use of tone mapping.

Completely Worth It

Having no formal software that could handle HDR processing (I mainly use GIMP and iPhoto), I decided to take the miniscule plunge and drop a dollar for this app.

Without a doubt in my mind, it's completely worth $.99 even if all you can get is one useable photo out of it. The only thing I'm seeing is that often the HDR effect you achieve with this program is either barely noticeable, or overly done. It takes a lot of finesse of the strength and radius sliders to get a useable effect that isn't insanely contrasted or overly fake looking. However, once you get the right combination of photos and get everything adjusted to your heart's content... this program does exactly as it's supposed to and does it quite well. Also, it's insanely fast and very, very simple to use.

Bottom line: It's a dollar, it's worth the purchase, and you'll likely get a number of good HDR images out of this app.

Won't auto register well and prior manual register seems missing.

I didn't have the prior version befor 2.1 but it had decent reviews for the price. Apparently the prior version had manual image aline adjust that is now missing and there is no help file. If you have a simple well defined scene it will auto-register fairly well. On a rural scene with trees and bushes it wouldn't register the images very well which gave it a more "painted" type appearance, not what I was after. Photoshop Elements 11 did a much better job of registering and both the auto and manual modes seemed to work well. It won't boost the range as well as LC but with post processing in PSE11 you could get similar results with better registration. Actually, picking the best of bracketed shots and applying filters with Aperture was almost as satisfying.

Like This A Lot

This app doesn't have all the presets you get with something like Photomatrix, but I believe you will be much happier with this app. It is crisp and to the point, and gives HDR images a very good rendering. This is not to be dismissed or ignored. I'm using an iMac with Mountain Lion and have had no issues with this app. It does everything it's supposed to do and it does them well. That's all I can ask.
