Is that you have to process the photos. As I am writing this, the pro phtoographer is struggling with getting her camera to work with photoshop and import raw files that she needs for her work. She does not like some of the tools that will do the job -- such as the open source ones I'm mentioning. The current raw converters that are out there include:
Capture One -- if you have a mac, probably the better tool.
Nikon Capture DX -- good for Nikon shooters (which we are). Interface with Photoshop -- not so good.
Adobe Raw Converter -- which is very fussy about what version of Photoshop you have (older versions don't have modern cameras, and won't work with the older. classic versions of Photoshop)
Darktable -- which I have used for years
Rawtherapee -- which requires other things for the next step.
The usefulness of open source.
I have a couple of other weird issues. I run multiple systems, using multiple operating systems, and want to use the same tools on each of them. My cameras range from farily modern to ancient. And I DO shoot raw.
Rawtherapee will export files directly to GIMP, which allows for the final stage.
This is an old photo of the Purakanui Falls: Nikkor 35 mm lens at F 5.0, half second exposure. I pulled out of the shadows some details of the bush, but the focus was on the rocks near the water. Signature then added in Gimp.
