I brought this up almost a year ago when Gamma D was still the go-to and was told I didn't know what I was talking about. In all the photos above, you will consistently see that Star Trek Beyond UHD is significantly darker than anything else when the same camera settings are used this proves 'dark' UHD titles are absolutely real. The photos above prove at minimum two things:ġ) Some UHD discs massively darker than their BD counterparts,Ģ) Some UHD discs are massively darker than other UHD discs. To obtain 'beautiful well lit' photos on UHD titles I've identified as dark, extremely long exposure times are required and these long exposure times are much longer than your eyes are able to adjust to in real life. A massively long 1.3 second exposure is needed to get enough light into the camera to produce this image. The HD shot looks about like this in real life.the UHD shot does not. Notice.the UHD shot is a full second longer exposure. Here are some shots from Star Trek Beyond, a title I've identified as dark with my CIH screen in 108" mode (and yes, it is still dark even when I zoom all the way in to 78"). If anyone chooses to directly back-to-back compare HDBD to UHDBD any title I've identified as dark, this is exactly what you will see:Īgain, these are the settings used with Autocal completed:ġ) HDR, BT2020, High Lamp, 0 Iris, Manni's 140-1100-4000 V2 custom Gamma curve.Ģ) SDR, Rec-709, Low Lamp, -12 Iris, Gamma Normal. If you wish to prove me wrong, you will have to take a UHD title I've identified as dark and take two photos with IDENTICAL camera settings (ISO/Aperture/Exposure) of the same scene on BD and UHD showing anything other than the UHD being massively darker (good luck). The following is my very last statement on the matter as I am using photographic proof. I have many UHD titles that look absolutely phenomenal. I am now simply trying to figure out how to identify what titles will end up being dark unless it is just a guess (I can't see a pattern as it has happened from different studios and even different titles in the same franchise). Everybody in this forum would see that if they simply compared the HDBD to the UHDBD. I know my settings are right and I know that some UHD titles are massively darker than their BD counterpart with any settings you choose to use. I'm saying to look at actual content and compare the BD & 4K of titles I've identified as dark.Ĭlick to expand.I've moved past it. I would never argue peak white is brighter on High Lamp Iris 0, that's obvious. I just want to figure out what the common thread is between these 'dark' titles. I just do find it amazing that nobody cares to look at the BD. I'm not trying to dredge up another debate as I know my settings are correct. The difference is so big that it really doesn't matter what settings your using, you'll notice an immediate and drastic difference between the 4K and BD of any of the dark titles I've mentioned. I'd just like to figure out the common thread between what makes a good and bad looking 4K disc. But you gotta put your light meter down, LOOK at the screen, and simply try a back-to-back BD v 4K comparison of one of the troublemaker titles I've identified. SDR in Low Lamp at -12 Iris vs HDR in High Lamp at 0 Iris and the SDR BD is still massively brighter on Ghost in the Shell and every other 'dark' title I've mentioned. I just posted my autocal calibrated settings above. I'm saying to look at actual content and compare the BD & 4K of titles I've identified as dark.
