Image Threshold Produces Black Image

[bob.wolff68]

If you're looking to change colorspace and see what happens, go back (or start using) NI Vision Assistant. After acquiring an image and beginning to process it, if you go to the "threshold" processing area in the 2nd tab, you can select "RGB", "HSL", "HSV" etc in a drop-down list and then play with the filtering min/max values. This will give you the ability to experiment and see what works best. Then use those values in your actual call in C/C++ once you're happy with it.

The white paper on target finding this year goes into HSL/HSV to a decent degree BTW.
