Invert tones for a negative

Jim MSP

Instead of using a commercial scanner, I am beginning to shoot my old slides and prints with my Canon 60D, giving me a very high res raw file to work with.
The slides & prints are easy to work with.

The negatives are another story. Is there a way in Capture One Pro to invert the tone curve, such as you can do in Photoshop, PSE, and Lightroom?
Is there a way to work with negatives that I haven't been able to figure out?

Thanks,

Jim

  I recall I read a tip here that suggested to invert the black and white point handles in the levels tool. You shit the black point from 0 to 255 and the white point vice versa.
  
  You are then still left the the orange mask (now inverted to blue, I suppose).

  Paul,
  
  Excellent -- this works.
  
  I'm getting a starting point similar to what an inverted tone curve gives.
  
  Thanks.

  Sorry Paul, but following your instructions to the letter causes the results to be crappy. 😊

  I guess I am not seeing what you are seeing.
  That said, I have only picked 4 negatives to "scan" this way, as I didn't want to waste my time if I couldn't process them.
  I am able to invert the resulting raw shot in PS, PSE, and LR. It gives me a starting point that appears decent.
  In LR4, I just reverse the tone curve by dragging the end points in the tone curve.
  Following Paul's advice, I seem to get the same starting point on the 4 negatives I've shot as I get with the Adobe products.
  
  In the LR forum, I have gotten a few responses to a similar question on processing advice, that that the results I will get are very dependent on the original negative and type of film used. One person said "After several hours of playing with DSLR-copied color negs--both in LR3 and LR4--It has been my experience that color negs are sometimes extremely difficult to reverse and have look "normal". Some convert well, and some never seem to. It may have to do with the orange mask being slightly different on different film stocks. Kodachromes and monochrome negs are no problem."
  
  I may not have shot enough negatives to see the bad ones yet. We will see. I prefer the way CO handles color, and I may be able to work through what LR cannot.

  Sorry, I was joking about your typo. Read your first response closely. I think you meant "shift."
  
  Your answers are always right on the money, as you've helped many people on this board. Thanks!

  LOL. I know he did, and I read right on through it.
  
  Actually, a few of my scanned shots look like "shift".
