In each case, you're seeing "after" and "before" images. The workflow for each of these was pretty much the same: create a good "normal" image in Lightroom CC 2015, and then open a "copy with Lightroom settings" in Texture Effects. From there, I generally started from a preset that had the general mood I though would go well with the image, and then customized from there. I should mention that most of the time when I start from a preset in any application, that's just the starting point. In some cases, by the time I'm done, most of the preset settings have been altered significantly.
Texture Effects is one of the most fun plug-ins I've gotten recently. Even better, Topaz are still running special pricing for a few more days! The retail price for Texture Effects is only $69.99, but you can purchase for only $49.99 ($20 off) until November 20th by clicking this link and using the coupon code: TEXTUREFX.
