Improved "AutoExposure" compensation estimation

Yes exactly.

I’m not sure if this will help in your situation, Jonathan - and you’re probably aware of this anyway … but, just-in-case;

  • You can select multiple images - and any correction that you then make will apply to them all (such as Exposure Compensation) … Just don’t forget to UN-select multiple images when you’ve finished.

Yes, that multiple editing is working really nicely. On top of it, it doesn’t just copy the auto-exposure value of picture number one to all other 299 - it treats all 300 individually. So, if you’re happy with auto-whatever @jsiie then there’s no need to click it for each photo separately.

I would like to recommend the following improvements to AutoExposure in DxO Photolab.

  1. Allow users to manually set the amount of highlights we want to protect or overexpose. Currently we have:
    a. Highlight Priority (Slight, Medium, and Strong)
    b. Center Weight Average
    c. Manual
    There is already an algorithm in place here that decides how to adjust the exposure based on data about the highlights. Assuming that “Manual” is just taking the actual camera exposure and adjusting from the static point (no automatic adjustment at all), what we need is a way to manually adjust the algorithm that already has the highlight data. For example, why not add a slider for “Highlight Priority” that includes both positive and negative values (-100 0 +100 where zero is “Highlights Slight”) and we can adjust the exposure to either protect the highlights or to blow the highlights to get the automatic exposure that we prefer.

  2. A very simple way to do the above would be to allow the existing “Manual” slider to work together with the existing Automatic Exposure settings. Why can’t we choose “Highlight Priority Slight” and then also adjust the exposure manually up two stops from the automatic exposure starting point (rather than all manual exposure adjustments starting from the original exposure set by the camera)? It would just mean making the Automatic Exposure options the starting point of the manual exposure adjustment, which should be simple for the software developers.

The above suggestions can sort of be accomplished in the current software by using gamma on top of the automatic exposure adjustments, but it’s not a perfect solution because presumably gamma doesn’t work the same as exposure compensation.

The discussion about how the photos were shot or improving the shooting conditions are irrelevant since the goal is to improve the DxO software so that it meets the requirements of photographers shooting under different conditions.

Hi and welcome here.

  1. A very simple way to do the above …

What you seem to be asking for already exists. After invoking one of the Auto options ( a. + b. ),
which then is your starting point, just grab the slider …

Thank you for the reply.

This is not a solution for this issue because it cannot be applied to more than one photo. It is not automatic, but manual adjustment. Following the steps suggested results in the following:

  1. Select two photos and then select “Center Weighted” Auto Exposure.
  2. Look at both photos. Photo A shows +.20 exposure. Photo B shows +.25 exposure.
  3. Select both photos again and slide the exposure slider to +1.
  4. Look at both photos. Photo A shows +1 exposure. Photo B shows +1 exposure.
    The expected exposure would be:
    Photo A +1.20 exposure.
    Photo B +1.25 exposure.

Unless I misunderstand, the suggested solution is the same as applying manual exposure to each photo. The goal is to be able to process large numbers of photos using auto exposure with a manual offset added to the autoexposure.

well, that is something else …

Well no. That’s not something else. That’s the point exactly.
