One sentence review: Great actions for beginner to intermediate landscape photographers, but advanced shooters will want more control.
The kind people at Landscape Sleeklens.com recently asked me to review their Aventure Photoshop Actions. These actions are "intended to speed up the editing process of landscape photographs while producing professional results."
I don't use a lot of actions in my workflow, but if you use photoshop, you know that there are multiple ways to skin the proverbial cat. For this reason, no two photographers' workflow will be the same. I find myself making the majority of my global corrections in ACR, denoising in Photoshop with a plugin, then making extremely refined adjustments with luminosity masks. These are fairly specific adjustments, that I want complete control over.
The only actions I consistently use are Tony Kuyper's luminosity mask action sets. Like most advanced photographers who use photoshop, I find that actions make too broad of an adjustment--however, this is not a bad thing. If you can find a formula or recipe of actions that you like, it can save you an infinite amount of post-processing time.
I really liked what the actions did for dark cloudy skies. but the actions at their default 100% strength were too much for my taste and found I had to take the opacity slider and move it to 10-35%
These generalizations about actions apply to sleeklens' Adventure Actions too. These are fantastic actions, but they don't give me the absolute control that I demand. If you shoot mostly JPEG and don't want to spend the time and energy to learn all of the ins and outs of Photoshop, these actions are perfect. Hit play and adjust opacity to taste is all you need to do to create some great images.
