Hi,

I've just started using this soft and can't get any results so I have few questions :

1. can I work with .jpegs, or only .RAWs?
   
2. If only .RAWs, will I be able to do anything with free version of software (.dgn conversion is available only in PRO version)?
   
3. Is there any tutorial video on how to proceed without Lightroom (Bridge/ACR workflow)?
   

Thanks in advance.

JPGs and RAWs will both work.
DNG Conversion is not needed at all.
Please watch my tutorial to learn, how the workflow works:

Lightroom is recommended, since there are Plugins available that make the whole process a lot easier. Bridge/ACR works similar too, those workflows are explained in my EBook (see banner on the right).

Thanks for your answer.

I studied both - tutorials and workflows, and my biggest concern is deflickering (image is still flickering after workflow). In which moment deflickering is applied to .jpeg's? After last "save"?

Thanks

Deflicker with JPGs will only work on the original previews, without any edits applied. Thus it's not as powerful as the new visual deflicker, that will work on the visual previews (but only for RAW files).

The results on both deflicker variants heavily depend of choosing the right reference area and smoothness.
