Dumb Question (Maybe)
How come when I open a new folder of RAW captures they look overexposed and then as C1 scans each thumbnail it adjusts to a more correct looking exposure?
Why the change?

Guitar,
I hold my ground is stating, there is no such thing as a dumb question.
What you are seeing is simply the manner in which Capture One builds New Session. In general, here is what occurs:
> A Preview file is created from the RAW .C1p
> A Thumbnail/Work file is created .C1w
> Color Management data is written to .C1w
> these data are read by the .C1p and image is adjusted accordingly
> Session is ready

But why does it look overexposed initially? 0 -
Guitar,
My guess is that it is missing whatever bit of data makes it look good, or correctly exposed. It is most likely the Camera Profile.
Remember, the correct camera profile gets set from reading the MetaData of the image file. Same goes for WB. These are the most logical as to why an initial image is way off... its not Done yet.
This is a question for a Developer, but it really is not something of concern. Open a new Session of RAW images and go get a cup of Java and let it finish its process. 😂

Well let me add this tidbit of info....
When I open the same raw file in CS2 or Nikon Capture, it IS very over-exposed.
Something just doesn't make sense. Am I shooting over-exposed or not?
Based on Photoshop and NC the answer is yes. But once C1 does its little adjustment, it looks properly exposed. See the conundrum?0 -
PS This is one of the many situations that demonstrate the need for a phone support option! 💡 0 -
Guitar,
Something doesn't make sense, I agree.
I'm not quite sure what occurs in the other software, but it seems the RAW data is handled quite differently. I wonder what Nikon or Adobe tech support would have to offer. Is it as simple as a camera profile?
I always put a lot of faith in my camera's histogram when judging exposure. And when shooting tethered, I can quickly assess the histogram in Capture One as well, before continuing a photo session.
It seems only a conundrum if you're still juggling the 3 softwares to determine which to stick with for an efficient workflow. Stay with what satisfies, but be sure not to spend too much time at a computer rather than taking photos. In this regard, Capture One is at least 50% more efficient in workflow.
Don't forget the Technical Support through creating a Support Case.
To be quite honest, phone support is a waste of Technicians time. In the duration of a 20 minute phone call, we can assist and respond to 5 or 6 other Cases with answers to problems. Spending time on the phone with one User, makes it quite unfair and inefficient to other Users. In addition, it is typical that callers seek a quick answer to get through the day's dilemma and forget about it until the next issue. These are the folks who tend to not get any smarter. A written exchange is much more efficient, and it is a good practice to have all tech support issues well documented. This make all Supporters more knowledgeable, more efficient, and more effective. Sometimes a Support Case requires research and testing, \" please hold while I go run a test on this camera\" just won't work. These written exchanges help other Users and provides Developers with great details and history should a problem lead to a Bug Fix. The efficient studios will print these Support Case exchanges and place into a binder for reference... they then get much smarter.
Sincerely,

Keith,
I read your post on telephone tech support and I basically agree with you.
However, I often noted on various web support forums that some issues are so badly worded and imprecise that nobody can offer a simple and relevant answer. Sometimes, it takes 3 or 4 questions to obtain a clear definition of the problem. I saw many threads on Apple Forums, for instance, where a whole lot of confusion was created because people did not use the proper terminology to describe an issue (or a solution).
My 2 cents... as they say in French, which is my first language and you can imagine the difficulty I sometime have to make my points clearly on discussion forums; fortunately, I went through Law School in a Canadian English University - a long time ago - and it helped me a lot in making sure I use the exact words even though I make typos and syntax errors. 🤭
Keep up the good work, Keith!0 -
I understand, and mostly agree with the last two posts.
My concern is, that I may be shooting overexposed. In which case I am loosing data, corrrect?
Perhaps C1 fixes that automatically, but I would think I am still better off shooting slightly under-exposed.0 -
GuitarAdoptions,
Geez, I wish I could help you. I was tempted to say send me one of your photos and I'll see if it comes up badly over-exposed here, but I realize that I'm on a Mac and you are on Windows. That would make a whole lot of difference.
For a while, I went back and forth from ACR, to Nikon Capture and then to Capture One. I finally decided on a workflow based on Capture One/iView Media Pro and went from there on. Keith is right about that but I don't blame you for going from one to the other because I have done the same thing. Each of these sofwares is extremely difficult to master and you may end up spendind your time on the computer and not behind a lens... (like I did for several weeks earlier this Summer).
Anyway, maybe you should open a support ticket and send one of your photos to Phase One to see what they make of it (although over or under exposition could be very subjective).
Good luck.0 -

What does the histogram show? I see similar histograms with C1 and CS and RSE so I wouldn't think that one program would see a correct exposure while the others interpret the RAW data as overexposed.

Hi Guitar,
If you are happy with the image data you see in Capture One, if there is nothing blown out at value 255, (or nothing you would reasonably expect would be pure white like specular highlights), all the detail you want to see is there, and the histogram shows a reasonable distribution of pixels across the expected range of values, then you don't have to worry that you are losing data.
If Nikon Capture and Adobe ACS render the same images as way overexposed then it appears to me that those software applications are not interpreting the data as best they could.
I hope this answers your concerns.
Best regards,
Eric Michelson-- filling in for your faithful servant Keith0
