Thanks Ross the camera is old technology I agree, 7 years is a long time with this technology and the free software is good that is on offer.
The dehaze option will be good and will look into the clarity more it is not that obvious when processing what is happening to the photo until the final export so a bit of experience will be required.
It is remarkable we have the Photoshop option with Adobe to keep these older generation cameras operating and do not expect Olympus or other camera brands to waste too many resources on older cameras photo processing software.
Will use the help menu as suggested Ross too.
Cheers Nick
