It works good for very steady cockpit cameras. But in VR that could kill your experience if you focus too much on YEBIS AE. Even with some headmovement the exp starts to wooble. In the last years we developed much better methods to calculate exposures. Also, if you just been focused on the windshield, you miss important parts of the influence by the illumination of the cockpit. AND every car has a different shape, the users have different FOVs and the seat position can vary with the cars.Hi all
Today I saw a query posted on a FB site and by chance, I stumbled across the solution yesterday, so I thought I should share my solution as many of you may also not be aware that you can choose the area which a PP filter uses for the auto-exposure metering.
Problem:
Most PP filters, but not all, run "Auto-exposure", which acts much the same as digital cameras always have, where the exposure is adjusted to bring the overall picture back to a pre-set overall luminosity. So in the car with drivers view camera, the shadow areas and black trim of the interior brighten up the overall picture, as the PP filter tries to compensate.
Solution:
Thankfully it's built into the "Post Process Filter" app that you would normally use to switch between to PP filters and make overall Exposure adjustments.
1. Right click on the filter name and select "Edit"
2. Open the "Auto-exposure" section triangle
3. If your PP filter has "Auto-exposure" ticked than the area can be adjusted.
4. Tick "Show auto-exposure metering area" - by default the yellow overlay will be full screen.
5. Use the sliders to adjust the size and position of the yellow area to only include the area you are seeing through the windscreen.
I am unable to adjust the centre point up, only down, which might be a problem for triple screen users only, not sure. Try tweaking the driver's camera viewing angle "Tilt" adjustment, to give you a bit more windscreen and less dashboard.
6. Untick "Show auto-exposure metering area" before saving the filter, otherwise the yellow overlay stays on.
7. Right-click the "Save changes" button, to bring up a "Save as" option where you can rename your tweaked PP filter. You can simply save, but i recommend doing a Save As so that you always have an original version of all the PP filters to revert back to.
This PP filter will now focus it's auto exposure on the road and scenery and not be distracted by your dark interior. much the same as your eyes when you glance up to look at the road outside in real life.
Differences are subtle of course, but often the road to perfection is a lot of a small improvements.
Tip 2: Another advantage renaming any of your favourite PP filters with something like your name at the beginning of the title is that your favourites will now all be grouped together in the PP filter app. Helpful if you have a lot of PP filters but only want to cycle between a few of them.
The best way is to have just a minor influence of AE for the exposure calculation and take more screen part into account then. So it also take dark places into account.
