is the link from which I got that image. I simply imported both images into Paint and reduced mine to be the same size. I added the side pillars to preserve the width. There was no tamering with the either image apart from resizing them to be the same size.
If you look at his EQ list you will see:
Jvc Rs-1 front projector
Hometheaterbrothers.com anamorphic lens.
Pioneer Elite VSX 92 avrDVDO VP-50 video processor
Toshiba XA-2 hd dvd player
Pioneer Elite BDP-95 blu ray player
Directv HD DVR
Sony vcr(don't know why I still have it hooked up)
Harmony 690 remote control
Why would anyone with a VP50 (which I don't even have) bother capturing a screen capture of a DVD?
As I said earlier, I have no idea of how he captured the image. When I take a screen cap, generally I use the screen to white balance the camera first. I always use a tri-pod and I use a timer of no less than 2 seconds to allow any possible movement to I might cause to stop when pressing the shutter.
The shot I took was done using my Fuji FinePix S5600 5.1MegPxl digital camera on the tri-pod, the MK4 anamorphic and a JVC HD350 (RS40?). Source was from a PS3 with HDMI through an Intregra AVR. No external VP was used. Screen gain was about 1.2.
When I take a shot like this, I use the lowest ISO setting of 64. I take a few different shots at different exposure times (any thing between 1.0 and 3 seconds) and run with the brightest image without blooming. Fstop seems to be an auto setting in this camera (S) mode and seems to sit about 3.2.
A few years back, I found THIS LINK
and sent it to MarkH in the UK because he has an ISCO III and a high end projector (3 chip DLP?). His feedback seemed harsh at the time - CA, astigmatism etc, however he is right. If I were to capture the same scene with my MK4, you'd have a very different result and almost the chalk/cheese we have with the rat. I use DIE HARD 4.0 as a demo disc in my theatre for clients because the transfer is so clean and I run it at 00dB for them as well.
So I am not picking on HTB per say. I am simply using the example to show the limitations of trophies when used as optical components, which whilst they gave us an affordable means to achieve an all glass anamorphic adapter, they are not optical grade and fall short.
Hopefully in a few days, I will have an MK3+C in my possession and will be able to document the difference between an MK2 (no correction), MK3+C (5 element prisms/cylindrical) and MK4 (true cylindrical).
