"I doubt Adobe are even going to support the XRF format
Have been tweaking around here....
... and updated Lightroom to 5.3 just to see if it would open the Sigma Merrills.... Nope!
So unless David Coffin fixes it in his next release, looks gloomy.
Interesting conundrum!
My view is: Suppose you were a manufacturer of a newly designed electric auto that needed to be recharged every 200 kms.
Other electric car drivers, before you, would locate a service station or a restaurant/ truck stop which permitted you to recharge while you ate or slept.
We have some like this....
But your new design has a PLUG with 5 Prongs instead of 3, and no one has an outlet to mate with that.
Do you expect all these service places to provide a special outlet just for your model?
Just spinning some thoughts!!
