I did see that you stated that it is not the filter. I am sorry if you misunderstood what I was thinking. I was not saying the filter is "bad"... just changing the light enough to affect the image in this particular case.
Is the filter's "normal darkening" affecting the way the processing is done?
Would the same scene filmed without a filter have the same results?
Don't take my mentioning "Pixel-Peeping" as a bad thing...It is not to say that you are looking for problems just that you are keen to the details
As I have seen in many of your other posts/videos you DO analyze ( Pixel-Peep) your pictures/videos meticulously, as do I. Especially when I first get a new product, just to find it's limits or "peculiarities".
The mention of P-Log causing this artifacting is disconcerting because I, as you do, relate that to as close to a "raw" image for video as it will get...Interesting
Apologies to you for my misunderstanding your reply. I look at "Pixel Peeping" as one who zooms in to 400% magnification of an image & then stupidly complains about it being pixelated! I will admit to being a pedant on trying to get the best imagery I possibly can with whatever tool I am using. I am not one to spend hours & hours on my editing though! Apart from my 6 minute long exposure photographs, I haven't used Photoshop in ages! I whip everything through Lightroom CC Classic very quickly, preferring to have captured it as close to my end desired output in the camera, rather than forcing a RAW file to become something it isn't. If that makes sense?
I'm going to go back to this place again today, to test out footage in a shoot off of sorts at different settings, to see what works best for a relatively high contrast & shady location. I'll compare the P-Log to Natural, particularly looking for this scenario again, but also check out your hypothesis of the Anafi reacting differently because of the limited light entering the lens. Thanks for sharing your thoughts!
I did hear Stewart Carroll from the YouTube channel
Drone Film Guide mention that he doesn't shoot in Log format with his DJI gear & I'm starting to understand why now.
Log is absolutely not RAW, it's a "workaround to retain dynamic range when you can't have RAW".
It's just a set of curves that is meant to "squeeze" a higher dynamic range than would be possible into a given file format That is very much processing, and lossy one at that.
Squeezing more dynamic range means mapping bright tones to less bright ones (so that even brighter ones can still be packed in), and dark tones to less dark ones (so that even darker ones can be packed in), aka reducing contrast. It does that to amounts that are not linked to what the particular sensor is actually capable of, just some "standard" amount, while this is only really useful up to the actual dynamic range of the sensor. A sensor like on most small drones including the anafi don't really have a significantly higher one so its advantages are limited.
The limit of dynamic range on the shadow side is "where the noise becomes unacceptable", so you've got to grade your log back to what the sensor allows for. You might gain some thing or not.
@Krusty Geeza didn't say at what ISO he was shooting, but my guess is he wasn't at lowest. Shooting log does an equivalent of boosting ISO in shadows, so if your base isn't the lowest things are going to look terrible. And you always want to have as much light as you can.
@Kilrah I can't thank you enough for your explanation here! It has me thinking very differently about how to use this bird now. I have been using it in full sun conditions in P-Log & that's why I haven't seen this issue before. I now understand it to be perfectly capable in that condition, but not for the light I worked in the other day, which was just prior to sunset, but not quite reaching the golden hour, with much more noticeable shadows & a lot of darker regions being captured.
Interestingly, to me, I did record at just after sunset using the same settings but with a ND 16 in place at the local beach & there wasn't that level of deterioration visible!
I had put the exposure details on the video at the very beginning as when I posted the original part of this thread I was being ushered out the door by my better-half! They are:
Cinema mode 24 fps
ISO 100, 1/50, 0.0EV, ND 32
I try & work with the Anafi as I do my digital cameras, keeping to the native ISO as much as is possible, exploring the limitations of each camera in regards to noise & detail trade-off's, then working from a tripod as needed to facilitate better quality image capture. I always take reference frames of my ColorChecker card, the large one, so I have a reference for colour to work with if accuracy is needed; with the Anafi I am doing this both as video & a DNG still frame.
Once again, my hat is off to you for your time & explanations here
@Kilrah you have indeed shown yourself to be the very gem I thought you to be!
