As a photographer, my main focus is landscapes, and my style is to try to keep my images realistic. Often, this means just using one well-balanced exposure, but at times, I need to use more than one exposure to capture what my eyes saw. Personally, I prefer to blend multiple images in Photoshop, by hand, but other photographers like the effect that HDR brings. For these folks, Photomatix is currently the king of HDR apps; amongst the challengers for Photomatix’s throne is Hydra – but is it regal material?
Hydra comes in two editions – standard and Pro – and the main differences between the two are the number of images which can be blended at one time (3 and 7 respectively), and the fact that Pro comes with Lightroom and Aperture plug-ins.
Loading images into the standalone app is easy – Hydra provides an image browsing window which allows you to view photos in your iPhoto or Aperture library, or on your hard drive. A quick drag-and-drop, and your images are ready for pre-HDR processing. The HDR-preparation process in Hydra is relatively minimal, largely consisting of EV (exposure value) and temperature adjustment, as well as manual image alignment, a crop function, and ghosting reduction controls. And just for the record, these work perfectly well.
The magic – a.k.a. HDR – happens on the develop menu. If you’re in a hurry, you can select from one of 11 presets, these ranging from “photorealistic” to “cyanotype.” For more control you can head to the adjust menu; here are all the standard image controls, which can be applied to the composite image.
There are two additional features, however, that make Hydra stand out from the crowd. The first is the option of “Snapshots.” During the HDR-adjustment process, you can make up to five different copies of your image, the idea being that you can temporarily save up to five different sets of image adjustment, and then compare them easily to choose the one that looks best. The other killer feature is “Probes.” Probes are basically local adjustments to your image, and they work in a similar way to Lightroom’s local adjustments – place a dot, and choose how large the area around it – the area to be adjusted – should be.
The other thing to credit Hydra with is quantity and quality of export options. Images can be sent to Facebook, Twitter, Flickr or your email app of choice, or sent to an iPhoto or Aperture library. Not all apps provide these options, and whilst they are inessential extras, they’re a nice addition.
Hydra Pro is a polished product, which works well. I feel it is aimed at the intermediate market – those who want some control, but don’t want to spend too much time obsessively fiddling with tone-mapping. At $99.99, I’m not entirely convinced that Hydra Pro gives quite the same bang for your buck as some of its competitors – compared to HDRtist Pro, for example – but equally, Hydra is a good buy in its own right.
