I use LR4 and I don't get the red issue in raw. If your processing the raw file, well...maybe I'm just old school.
The GR files need gentle processing with noise to zero and sharpening also.
LR does a great job if your not aggressive....
Wells this is the first time I'm really digging into the RAW files and have decided to try out DxO Optics Pro 8.2. I like the auto lens correction and the basic default touches it puts in because I'm usually lazy when it comes to these. Think I can skip the library curation features of Lightroom for now as I don't mind manually organizing my files in (Windows) Explorer. Might just pay for it when my trial ends..
edit: My Dell XPS 12 (i7 + 8 GB RAM + 256 GB SSD) is getting toasty after processing 18 RAWs on battery, hahaha...
Reds issue? A lot of red hot air before the camera was even released from a test image. Funny that the camera has always been able to get its reds right in in-camera jpg files ..... Nothing to do with processing raw files later with software?
The best raw converter is in the cameras own raw file converter if you get the camera set up correctly.
However you can repair capture errors and improve on perfection with a raw file converter. I have used Capture One for years. I think that there will be many different recommendations, we all get used to the one we use and they all "do" raw. However some other raw file convertors are very basic and others have terrible interfaces. LR1 which I was generously given when they bought out the much more capable, cheap, "Rawshooter" was all glitz and not much content and they soon enough were wanting my money to upgrade my free copy to LRII. I believe it is a much more capable product now it has been upgraded - version V maybe?
To understand: "Rawshooter" was a product that seemed to be produced by an ex-Capture One employee. It had a better more intuitive interface than the then Capture One and was nice to use and powerful. But it was horribly buggy and crashed a lot. I expect that a lot of what made it tick was incorporated in later LR versions - get the drift?
Anyway I went back to Capture One and they had improved their working interface out of sight and their upgrade policy is not as $$$ as that of Adobe.
As mentioned - some of the others are pretty basic as far as I can see and I sometimes wonder if they are simply used because they are free and folks can say "I processed my raw files".
From what I have heard so far the GR's in-camera raw tools seem to be no more than applying some post-capture "effects" in-camera. I look forward to the day when an in-camera raw image pp tool can provide similar adjustments to that which we buy pp software to do.
