Yes Capture One, when it loads the "film" curve is adding quite a bit of exposure or something, as you can watch the thumbs pop as they load, however the features/and tools of the Capture One have long appealed to me (minus the history of adjustments as everyone knows). With a Phase One back I will always feel it gives the best results and I am a big Lightroom user. I have long questioned the reason for the pop as images load and you can easily get around it by using a liner curve, (which I use at times). This pop used to drive me crazy with my P45+ as often the images did not have blown highlights until the pop of the film curve was loaded. I find now with the IQ160 files that this
I am most likely not as detailed as Eric, as I am happy to use the stock profiles that Capture One provides as they give me good results, I often do shoot a xrite colorchecker in the field and adjust my WB from that. This works about the same in LR as in Capture One, but I don't take it the next step and create a camera profile. I feel that Phase has the profiles for their backs down good, but there is room for improvement on other cameras. However I understand that is not a 1st priority for them. With cameras like the Nikon D800 LR offers many different profiles to start with, but for example with Fuji only one.
There are some images that the color selection tools of Capture One, just work better for me, and then others that the LR color tools work better.
Using a tech camera 100% with my digital back, thus requires a LCC. I never got the handle on the LR method of doing this and the attempts I made did not produce good results. Capture One has got this down pat, and their corrections are excellent.
I work in session mode in Capture One, have no desire for catalog and would love to see a session option for LR. I don't feel the need to catalog all my images especially in my workflow.
So as always it's an individual's choice and both are excellent tools.
