Yes, they do with tweaking to your liking.
Presets were tested on all the latest Canon, Nikon, Sony and Fuji cameras.
My recommendation would be to use RAW files for much higher quality results from your processing. That said, you'll have just as much fun exploring the possibilities of presets and profiles with any images you have in jpeg format.
After you checkout and finalize the payment you will receive an email with links, from where you will be able to download a zip file with the presets and the profiles and an installation guide.
Let's be honest - every preset and profile will probably require some minor tweaking in order to achieve the desired result. But it shouldn't take you more than a few moments and all tweaking is mostly happening in Basic Settings Tab.
Presets and Profiles are meant to make your post-production workflow faster and color editing more consistent.
Before applying any of the presets, make sure to adjust the exposure and white balance of your image. Then apply the preset and if needed make minor adjustments in Basic Settings Tab.
You can always explore and tweak presets to your liking and save them as your own variations for future use.
