Hi David,
It’s not uncommon to find (in an image-specific sense) that DP-XD is not providing much benefit over DP - but I am surprised to hear that it’s worse.
There’s discussion here on the type of image for which DPXD is best suited - with general consensus that it’s worth applying mostly on heavily cropped images … Otherwise, there’s often no visible advantage over DP (and, DPXD comes with a processing time cost).
- So, perhaps the simplest approach for you is to use DeepPRIME (and not DeepPRIME XD).
Which lens(es) are you using with your OM-1 ?
