UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
OK, bit brain dead today,
what is the best way to get a luminance file from an RGB file?
input rgb combine, balance, then move colour sliders to 0% and save?
or am I overcomplicating things .
thx
I'm not 100% sure (I asked Mabula on this one as well), but if you have a RGB sensor, I would probably split the channels for all data (tab 2 all the way down). This gives you mono data of each channel, then you load these in and assign them all to Luminance and integrate. I think that gives a pseudo-luminance result already, you can combine this with the integrated RGB data.
Hi Andy @andybooth,
Luminance from an RGB file can be made using any arbitrary formula for the luminance from an RGB image like this one:
For example a common formula for luminance is that the luminance is based on 20% R, 70% G and 10% B:
With the RGB Combine tool, set all R,G,B sliders for the input channels to 100 and set the L slider for the input channels in such a way that you get that formula:
Now, this result is a 3-channel image, if you split it, each channel is the same and can be used as a luminance for the image 😉
I have added to our issue list to make this easier 😉
