I agree that greater image fidelity is a good thing to pursue, but how much can you really notice the Darbee's subtle changes on moving images?

In fast moving action scenes, it won't be noticeable. In scenes that are panning at a slower rate it is noticeable. The detail it brings out in faces like eyes and stubble is quite good. Also scenes of forests, trees, grasses it is very noticeable.

You just need to take a little time to choose a setting that works for you. I choose HD mode at 50%.

OK. So do NOT watch "The Grey" with the Darblet turned on. SOOOOO much added film grain from the studio that it makes the image look like white and black sand is always flying, even when it isn't snowing in the movie.

I hate it when they add so much artificial grain to make a film "grittier."

i've never seen grain anywhere inside or outside, so i would love to see all movies without grain. grain lowers resolution .

you should try this to see how it comes out as regards fine image detail:
play the resolution pattern from a video calibration disc, and look at what happens to fine details and lines. this may be the best way to set the controls on this Darblet.

i would be very interested to read your comments about this.

On a clean input (no grain crap added), the image is definitely clearer and more defined. I just need to watch a good flick instead of these grainy-crap ones.

Maybe it is time for LOTR Extended!

One movie where you see a big improvement is in Avatar (extended) at about the 0:06:30 mark where you see the spaceship approaching Pandora. The detail of the spaceship just looks so much better. If you have the Darbee just turn it on and off as you watch the scene. Also if you happen to have the Bluray of Timescapes from Tom Lowe (look it up, it is mind boggling) the night skies (and everything else actually) look so much crisper. Basically, you need a good high quality source to get the best effect.

I can't say that I have watched a grainy movie since I installed it a few weeks back, I'll remember to take notice next time I watch one.

I have a calibration disk ripped so I may take a look at that but at the end of the day, I am sold on it and won't be removing it.

I've got the AVS 709 disc that I can try. I will also pop in Avatar...

Does anyone know how they work? I'm assuming that they just EQ the high frequencies for more detail? Does it have a tendency to get "edgy"?

the way you describe it reminds me of a tool in Ps.

it's the midtone adjustment in "image-adjustments-shadows/highlights and you use the "midtone contrast" adjustment at the bottom. it does not change overall contrast, i.e. it will not alter the black or the white portions of an image, and using it with care will seem to sometimes lift a veil in large parts of an image, or seemingly increase contrast and detail in parts of an image where there are small details.

of course, what it does never increases detail (resolution) really, but it can give a very good impression.

i have no idea how this Darbee works though.

In case you haven't come across this thread on AVS.
