Digital Light & Color

I have been experiencing a miss-match of an APPLY/OK image from the Preview for the Composite-Hard Light transform for 16-bit BW images. This is also true for PWP6.0.10-32bit...

An Apply or OK resulting image does not consistently match its Preview when:
(1) Extract the Luminance [or any other channel] from a 48-bit color image...
(2) Open the Composite-Hard Light transform where Input=Overlay=the Luminance image.
...(a) select Apply/OK with Auto Preview checked and Input Amount=Overlay Amount=100. Preview and the Apply/OK image match.
...(b) change the Overlay amount to be less then 100 and select Apply/OK. The Preview will no longer match the Apply/OK image. If the Overlay Amount is 99.7%, then the Apply/OK image appears "black" or has a HSV-V=0.4%.

If the blend is changed to Soft Light or 24-bit color/8-bit BW images, the Preview and the Apply/OK images will match through the Overlay Amount range 0 to 100%.

Vista 32 Home Premium, SP2, latest version/updates
AMD Athlon 64 x2 6000+ processor
3 GB DDR2 dual channel RAM
2 MB ReadyBoost Cache
500GB hard drive with 100GB free space

This should be fixed for the next beta release.

Thank you Jonathan...

FYI re how this observation came about... ...is that sometimes to make a BW image version of a 48-bit color image, I will Extract its Luminance channel and either Composite - Hard Light or Soft Light it with itself.

Most times, a low Hard Light Overlay Amount say 20 to 40% will achieve preference crisp/contrasty mid-tones without adding objectionable blocking to shadows/highlights.
