Interesting comments all. I hope everyone continues to play nice. In full disclosure I have no particular opinion about the matter, except I don't buy the concept that consumers are unknowing ...

So on many occasion there are questions here on how to convert video filmed at a particular framerate to another framerate. Posters then give their opinion, offer methods, etc. For the aspiring ...

Here's an simple workflow: 1. upload image in question to: nova.astrometry.net It will then "plate solve" and tell you exactly where the image represents in the sky. Download Stellarium , a very ...

For a different purpose ( to determine whether transient objects are there or not or are beyond the limiting magnitude of my videos/timelapses), I am often determining the resolvable threshold of ...

"And let's not get side-tracked by talk of the a7S cameras being great for low light stills......"
?????? Just one reference to how the author of this gossip has no understanding of the a7s model...

I understand that DPR is mostly a gear geek and consumer user site, but the continually quest of people to find a universal super-hero thing misses the mark. If one wants to do anything well, ...

Exactly. When people complain about banding, esp. in the sky, it is necessarily user issues. Yes hardware limitations will not currently present the infinite range of shades that we see in nature, ...

Sorry but what I don't understand is the really imprecise advice that had been offer on this thread? to get the most of the "see in the dark" effect, you will need: #1 (missing from this thread) ...

I guess a lens is too sharp when it leaves cuts on your hands. :-P I do find the humor in tech being toooooo good, as I experience similar issues when shooting realtime astrovideos and my ...

Don't have the patience to argue about this. Don't be misinformed. The a7iii has HLG and Slog3 options as well. Atomos doesn't require Slog2. How one shoots can take advantage of external recorder ...

????? Note to forum readers. Take the above as one bit of information. The statement that one must shoot in Slog2 is also misleading and doesn't really make sense. Color bit depth and the ...

Some (never repeatable) footage I have is worth doing it by hand. I've learned a lot of short-cuts. Understanding the entire concept without leaning on some automatic method has also taught me how ...

While hyped bad science publicity stunts that won't come close to the promises (just like rocketlab's humanity star), good efforts go unnoticed. (like this one:) https://www.youtube.com/watch?v=Rvg ...

I imagine anyone who has taken out their camera and mistakenly forgot their cards laying beside the computer, might appreciate the idea of internal memory. For all those 'pro cameras must have two ...

So there are a number of things that limit the information we can capture and experience: (1) 1. the display (2) 2. the equipment (lighting, optics[lenses], sensor)…

I've had my a7s for over three years and it is still doing fine. I haven't put so many clicks on the mechanical shutter, as I bought the a7s for the silent e shutter so I could do many timelapses ...

?? I don't see how your feeling on this is accurate. If you research the effect you experienced, regardless of camera system, the overall majority of the cause is the SD card itself since it wasn't ...

Without taking time to research the particulars of the sensor, etc. to speculate on how your particular achieves the particular resolution video, let me share two points to the more general ...

I just thought of a workflow, no time to test it at moment: -id feature in quadrant near edge in all images, -make proxies by cropping to quadrant, -stabilize proxies taking note of keyframe ...

In my mind the advantage to using LR is color correcting/grading at original resolution. Your sit. loses this. Whatever timeline you used in Resolve, in re-sampling.the resolution for vid, you ...
