Lg e8 oled screenshot test

You could refine the experiment by exposing for 1/60 second and 1/30 second to see if the pattern integrates out in one field or one frame.

Understand, good idea.

Took up Wayne’s suggestion.

#1 SS1/30 No pattern!
#2 SS 1/60 No pattern!
#3 SS 1/160 Pattern
#4 SS 1/160 Pattern.

#5 is SS#1.
#6 is SS#2.
#7 is SS#3.
#8 is SS#4.

The SS’s with the patterns look better and more in focus to my eye on my high resolution iPad with DCI P3 color gamut.

Edit: Images were not paused.

Excellent!

The pattern creates artificial high spatial frequencies (sharp differences between adjacent pixels) (aliasing) that are not in the source, so there is an impression of sharpness, but it's due to false detail that sometimes falls symmetrically about an edge and sometimes distorts the position of the edge. So, it is both sharper and distorted. The fact that it's a grid pattern and is finer than detail in the original, apparently prevents it from forming obvious jaggies, but it really is just another form of artifact.

The clarity makes it very obvious that the 16 year old Farm Girl, living in depression era Kansas has some very expensive Hollywood Makeup!

I’m teaching myself to shoot and process RAW files. We found an app that allows my iPhone X to shoot JPEG and TIFF files simultaneously, and with Lightroom, was able to render these five OLED images from our LG E8. My first foray into photo editing. There is much to learn and haven’t looked at color channels, tone mapping etc. I’ve noticed increased grain that’s hard to remove, but came out okay. The images are from a Netflix series Bridgeton in 4K Dolby Vision HDR. Tiff rendering has opened my eyes to what we’ve been missing. Big difference in quality. I’m a believer.

The only reason I’m not using my Sony A6300 is because of trouble transferring Tiff files from camera to iPad. Links are higher resolution.

Very nice. When you use compressed files instead of raw, the compression may accidentally remove some noise along with detail that you would like to have. The uncompressed TIF file will carry both noise and detail, so you have a chance to try reducing the noise with post processing. This may reduce detail somewhat also, but it will be controlled and not accidental.

Thanks. Agree.
In the first photo, the white door was washed out, the panels were barely visible prior to editing. The edit brought detail below the mantel and details within the bright sun in the rug. With the museum shot, I tried to remember the lighting in museums we visited. Had the opportunity to visit the Louvre and the areas were darkened with the artwork prominently illuminated. With the carriage shot, looking at the jpeg, I didn’t know the scene was shot in the late afternoon, also the blacks are not crushed and the white horse is not clipped.

New wide color gamut (WCG) images shot in Tiff and converted to JPEG to reduce file size, browser and monitor compatibility.

LG OLED, 4K, Dolby Vision HDR, Camera iPhone X. Best viewed on WCG monitor.
