Adobe Camera Raw converts RAW files so that they can be edited in Adobe’s products. If you use PhotoLab, it allows you to work with RAW files without the need to convert them until you finally want to export them.
When PhotoLab exports to DNG, it creates a file that has been converted from its original RAW format, processed and then exported. It is no longer the original RAW file but a linear DNG, which is usually several times the size of the original RAW file.
So, now you have two files - the original RAW and a large linear DNG copy. A simple question - why?
I am not talking about HDR in the sense of taking multiple shots and merging them. What I am referring to is making the most of the DR that your camera provides. In order to benefit from a camera’s full DR, it requires shooting at low ISO, exposing for the highlights and recovering the shadows in post processing, which is a totally different thing from what most people think of HDR. And which camera you use is totally irrelevant.
What I don’t get is why you are making a big fuss about having to treat Fuji files differently to any others that we have been working on for years in PhotoLab.
You may well be a “seasoned professional” who is used to using non-DxO tools but, if you are new to PhotoLab, you certainly are not a seasoned user and may not yet have understood that PhotoLab is not just a RAW converter but a fully fledged image processing tool that can do almost everything that other apps can do without having to go back to them.
If I give advice here that happens to mention basic photographic techniques, it is because, over the many years I have been teaching photography, I still come across people who are “doing it the hard way”, stuck in the rut of “this is the way I have always done it”.
I also shoot large format film and have to scan 5" x 4" negatives and transparencies to TIFF files, so I am well used to using PS. Before I was introduced to PhotoLab (v1), I also used to use ACR and Photoshop to process digital RAW files. It took some time to get used to PL’s way of doing things but, once I realised that I no longer had to mess around with multiple apps and get stuck with duplicate RAW/PSD/TIFF files, I found that life was so much easier and I didn’t have to pay Adobe every month for the “privilege” of using their over-complicated software.
And, don’t forget that advice given here is not meant solely for your benefit, it forms part of an archive that not so seasoned photographers can refer to.
