Very informative! Thanks so much for posting this, I'm going to try your software!

[@dave77777777]

Thanks for this useful information!

Thank you for posting the video, quite interesting! Do you use a cpl or linear filter on the camera?

[@GrzegorzBaranArt]

Great video guys, big thanks for sharing :). Regarding [10:06], how about adding an option to paint/mark the light on a chrome ball when images were crosspolarised directly in the app?

[@VFXGrace]

For now, our software can only paint the mask of the chrome ball. It can not paint the light on the chrome ball. You can paint the light in any 2D image processing softwares, like Photoshop, Affinity photo, Gimp, Krita, etc., and import it into Details Capture.

Awesome! I have a question. What about lens distortion? do you think it could cause the Normal map will be uneven? And also, what angle will you suggest for the lateral light? I read and some suggested 45° but also I saw different light angle configurations.

Clean and amazing results! I would love to use your softwawre but im not sure what camera should i buy. Which one did you use in the making of this video? The lens is visible so I have at least this much info 😅

[@VFXGrace]

Thank you for your support, we are using sony a7 iii. But this actually has no special requirements for the camera, as long as it can support shooting HD pictures in full frame or half frame.

@@VFXGrace Thank you!

I don't have a chrome ball, but I would like to make a lighting file to use for all captures, as the light source angle is the same for all of them. is this possible?

[@VFXGrace]

Yes. But the results won't be that good. And the color of the generated normal maps is a bit different from a correct normal map. So, to solve this problem, you need to generate the normal map one more time. That is, import the generated normal map and then export a new normal map with pre-correct checked.
