self made LUTs work not

[beertje53]

You can also create and store your own Luts. But there is a catch here. In version AP1 it worked without problems, in AP2 I have not yet succeeded in using my own Lut. Yes I can load it from the saved local folder, but it does not work.

“does not work” is a too vague for us to have an idea of what the problem could be.

If you can share the LUT, and an image you are using it with, and tell us what you would expect to happen when applying the LUT to the image, we can have a look at them to see if we can find what the problem is.

Try to place these on any photo, you will find that it fails. It does with LUTs I get off the internet. But where it goes wrong I don't know, on AP1 it all works.

Thanks for sharing the LUT.

I’ve just tried to apply it to the same image in both Photo V1.10.6 and Photo V2.4.1 and nothing seems to happen.
I tried a very different image, in both, and nothing seemed to happen with that either.
Same in Designer V2.4.1.

Hopefully one of the LUT experts will come along and be able to explain what’s happening.

It's an identity lut which will do nothing. Note that nested adjustment layers are not included when exporting LUT, the adjustments must be above the image layer

Below is a comparison taken at random, mine's on the right

dear, if I have an image, I put a pixel layer on it, fill it with color, reduce it with opacity so I have the desired intensity. export this as a LUT, remove the pixel layer, insert the LUT and it doesn't work ?

[David in Яuislip]

Check the Help for "Exporting custom adjustments as LUTs"
Possibly use a Recolour adjustment layer

As David mentioned, you need to use Adjustment layers. That is what the Export LUT process uses.
