Re your blog mention of RWL - might have guessed
Adobe were involved! QUOTE
RWL is a raster file format that is used for representing photographs captured by digital cameras, especially Leica ones. RWL was initially created by Adobe System to function as a graphic format for archiving RAW images.
Considering RWL files are unprocessed, they cannot be printed and modified with common graphic editors.
When users want to access RWL images, they will require specialized graphic viewers.
Amazingly, RWL does
NOT feature in the list of 200 formats that can be imported by
Graphic Converter. But if you want to experiment you can download and try it free.
And we were quite warm down here too - sat in the garden and enjoyed a couple of choc ices we bought last summer. Summer was July 17th IIRC
