Just setting the > maximum value to 253 should solve the problem. > JF, the intent here is to cover all the range of values available in Auto Exposure mode too, doesn't this make sense to you? I could set .maximum to 253 to limit the "UI" control precision but then I should use 2*value when setting the registers in order to cover the actual max value, this looks a little unclean. Anyhow, let me know what you prefer, I have no strong feelings on that. If you want to save a byte, I'll agree.
