Anyway, like Tom says, this is a starting point and can be adjusted to taste. It would be great if those that use it as is and in a changed state posted some stills with info.

Thanks for the support,

I'm leaving the matrix settings and RGB gains as you have them. Only the color gain, gamma and black level am I experimenting with. I don't see a problem with stills. The plasma however is more revealing than the LCD / PC monitors I'm using. I note that at +40 color gain setting, the processing seems less forgiving of the white balance. It might not be noticeable in mixed daylight, but in the current flat light, it shows up as a noticeable cast. But it's an "equal opportunity" cast because I saw it tend toward green at one end, and magenta at the other, without preference. It seems to be a consequence of the color gain being so high that the noise floor is on the threshhold of skewing the whites to either direction. But otherwise, the balance seems to be right in the center.

My last post slipped in after your latest stills, which look beautiful. Nicely saturated, and very clean, perfect balance.

Tom Roper April 8th, 2007 03:13 PM

...And beautiful bokeh! What zoom position and f-stop on those close ups?

Steven Dempsey April 8th, 2007 03:19 PM

Uh, don't remember the f-stop. I believe the iris was almost completely open and I was fully zoomed in. I took the shot from the other side of a large room.

I agree completely and good observations. According to the Imatest software, at sharpness setting "0" the sharpening radius is very close to the 2 pixel radius standard sharpening level. HDF=high seems to apply a subtle high frequency filter to reduce moire and twitter, think bar code labels. On mid, I think the filtering is reduced permitting a reduced sharpness setting = 0. It's hard to see, but increasing H/V detail seems to raise the vertical resolution, but at unknown cost to the horizontal. I chose to accept the defaults since the picture is clean and artifact free.

Do you know how this would work or relate to the XLH1?

Mike

Steven Dempsey April 8th, 2007 04:08 PM

No but you might want to try approximating it and see what happens. The tuning on the XLH1 is not as fine as on the XHA1. The scales for the matrices and the rgb gains are 1-50 on the A1 and 1-10 on the H1. I would say use your best judgment. Chris Hurd did a good job of approximating my Panalook preset which I created for the XLH1 originally.
