Improving lighting in object capture

you can brighten the texture itself in any photo editing software. chances are if the texture is too dark that your source images are also underexposed. you can use an external LED lighting setup to help with that.

Thanks for the tip. I created a batch in Photoshop that brightens the image and that does help. Photoshop doesn't support saving in the original file format .HEIC, so I'm using .JPEG. Problem is that the size data of the object is lost in the process, so the object created from the images in my example becomes too big.

Is there a way to retain the size data of the image when converting to .JPEG? Or copying it afterwards? Removing the gravity and depth files when processing .HEIC -files has no effect, so the size data has to be inside the .HEIC -file.

Thanks for any help!
