One of the greatest thing about the Sleeklens workflows presets are that they are 'stackable'... meaning that their effects actually complement each other, rather than cancel each out out... so you have so much more control than you do with regular presets that you purchase as 'one-click-wonders'! Their 69 presets can look a bit overwhelming at first, but they are categoried into easy sections (All-in-ones, base, exposure, colour correction, tone/tint, polish and vignette). I'm always sceptical about 'all in one' presets... because they never look the same on images as they do on their on the sample images that entice you to buy them! Some of the Sleeklens 'all-in-ones' are far too heavy for my natural, clean style... but having customisable, stackable presets is a huge asset. It's great to get a different perspective on how products can be used by looking into how they have created their presets, to then tweak them to our own preferences.
