Lately I've been thinking about why I purchase some movies released in 4K (Physical Copies). I've been focusing on older films released in 4K. I purchased Blade Runner a few weeks after I bought Blade Runner 2049. Because of 2049 I was able to appreciate and understand why Blade Runner was such an influential film which has such a large cult following. At the time, Blade Runner was the oldest 4K film I owned. Alien was released a few months ago and this was one of those "Day One" purchases for me considering it's my favorite film of all time. At the time, the HDR and Shadow Detail really stood out for me. Newer films viewed in 4K have been hit or miss, and as a result, I would simply rent the HD version.I recall having a few discussions on this forum regarding purchasing habits of 4K content and I was more on the "Stream the content" and purchase it if I really enjoyed the film, side of things. This is still my stance, but when it comes to older films, I'm now more willing to make the jump because I know I'm going to enjoy not only the film, but the improved presentation/resolution. Sunday morning, I was doing some house cleaning, and I had Lawrence of Arabia playing in the Background. I only have the Blu Ray but this film just looks incredible no matter what. After I finished cleaning, I sat down and watched the rest of the movie. I then proceeded to pull up 2001: A Space Odyssey. Again, only on Blu Ray but I plan on purchasing the 4K disc pretty soon. It's been a habit of mine to watch these two films back to back. For me, with these older films which now includes Apocalypse Now, its all about Resolution. Yes the HDR looks great, but if you turn off that feature, the films in SDR looks just as awesome. That's not to say I did not notice the improvement in resolution for Alien, but now I can really see an improvement. It reminds me of working with RAW files I take with my DSLR. You can adjust and pull out so much detail from an image in this format compared to a jpeg. After doing some reading here and there, this appears to be a similar process with older film prints. Now take a movie like "Bumblebee". The video presentation looks awesome, and it's not over-saturated like a Michael Bay film. However, in this case, the HDR and WCG really stand out compared to the resolution. Many of the Marvel Films currently streaming on Disney Plus fall into this category as well. In the case of the older Star Wars films on Disney Plus, the resolution stands out more compared to the HDR. These films are not intended to be colorful Pixar films to begin with. So for older films, it's Resolution. With newer films, it's HDR/WCG. Considering my 4K display is only 55 inches, the fact that I can see an improvement from just 8 feet away is all the reason to continue to focus on older titles. Also with HDR, this format is intended to be viewed in darker environments. It's intended to increase highlights in images. Now with that understanding, I'm better prepared to view films. Now, watching them with lighting adjustments as part of the equation, make the experience more enjoyable.
