Hi Oliver,
I did a sunrise test with my Canon R7 using the following settings:
Mode: ISO → TV
Algorithm: LRT modified Sunrise Beta*
Camera mode: M
Autofocus: OFF
Stabilizer: OFF
Aperture: fixed
ISO: manual
When the sun appeared, I noticed that the Unleashed only applied a TV (shutter speed) correction, but no ISO adjustment at all, even though I had set it to ISO → TV mode.
I stopped the timelapse (and therefore the Holy Grail process) to try other modes, but nothing changed.
👉 My question: are there any specific settings required for the Canon R7 to make this work properly, or is this a known bug that has not yet been fixed?
Thanks in advance for your help!
Sunrise test on Canon R7 – only TV correction, no ISO
Dont expect any answer from foolography. They are dead and/or not longer interested in providing support. An annoying situation since a year now.
Trying to help you:
ISO -> TV means that first the ISO is going to be changed and then after reaching the ISO limit you have set, TV is changed. So it depends on the ISO value you have choosen. So it might be normal that ISO ist not going to be changed.

They had tons of warnings and feedback given by users, supporters, customers, etc, but they ignored their loyal customers. They even ignored the clear evidence given to them by technical experts that gave them so much valuable help during the development process, but they had too much pride to abolish and ignore the feedback they were getting. They saw it as personal criticism (their "baby") instead of criticism of a flawed design (the design was flawed, not the people behind the design), while the feedback was to inform them of changing course, not changing their goals. They refused to listen and now the situation is a dead-end street were they couldn't get out of without doing a recall of the product. Terrible situation, but they got themselves into this mess because they kept on going in the same state of mind that did not promise much good for them and their customers. This is sad, but true. If only they had listened to good advise... The Unleashed product of 2018 was flawed in design, but to repeat the same mistake twice is not a development fault, but a subborn mentality problem that caused them to not redesign the hardware and software for the Unleased 2022. Repeating the same mistakes twice is a sign of limited selfreflection and an overall bad concept of the reality you are in. As Albert Einstein said before: The definition of insanity is doing the same thing over and over and expecting different results. They had their chances to undo their previous mistakes made in the 2018 version and not repeat it in the 2022 version. They did not. Instead, they used a flawed foundation as their base design and built on top of that for other camera brands. That can only go well, if the base design is cleaned of any flaws made in the previous design. Ironing the flaws out of it should have been top priority for them. They chose differently. What you now see is the end-result of bad choices. I find it a tragic situation for all: themselves and their (loyal) customers. Nobody benefits from a company going sour.

This is a clear case of not listening properly to the feedback you receive and discern the difference between critisim to pull down or ciritism to build up. Not all feedback that is mentioned is helpful, but the feedback you get from different persons, levels and devices, should tell you that something is not going right. Ignoring that, is ignoring your customer. And in the end your company does not benefit from the early warnings given. When you have received too many warnings, you have lost your ability to change course so that you achieve the goal you had in mind: a working product with the specifications and marketing promises given beforehand to your loyal customer base.

Many Thanks for your help but I'm lost , I received following answer from Foolography team and tried for Sunset and works :
Sorry for the trouble!
Hmm, no, we have not heard of this issue yet.
Could you try the EV-24h algorithm, to see if it behaves the same?
For testing, you can also simulate a sunrise by covering the lens with your hand and slowly opening it to let in more and more light, and watch the Unleashed change the settings.
The LRT Algorithms are quite special, and only react in one direction, so making adjustments to compensate for over or underexposure will not immediately show a change, it will just delay the next change, which feels counterintuitive, but it's how it is designed by Gunther Wegner, so we kept it exactly as his design.
We made some improvements in the LRT Modified Algorithms, such as immediate adjustments on the next image.
the EV-24h algorithm behaves in the most intuitive way, so it's good to make sure everything works with that one, then test the others if they give better results. To be honest, especially with Mirrorless cameras, it will usually give very good results!
We do most testing with the Tv->ISO->Av setting, so that's also good to start with.

Oh, one more detail, which might explain your problem:
the Ramping order Tv->ISO->Av is the order for the Sunset, on a sunrise the algorithm will actually use the reverse of this order.
So if you set it to ISO->Tv, it would use that order for a sunset, but the reverse for a sunrise. So you would actually need to set it to Tv->ISO for it to first reduce ISO on a sunset.
We have planned to add explanations for this in the app since a long time, but simply have not found a good way to do so. We are also working on overhauling the above support pages, but have not yet managed. Sorry about that.
