Noob question Re: GH5s and V-Log
-
Ok, poor choice of words on my part when I wrote ‘made up’.
But, it is a hack to fit dynamic range in a codec.
What do you think, that codec developers don’t know about math? It’s a trade off, and a poor one when it is not needed. I’m not going into discussion about that. (And I’ve yet to see an A/B comparison where Log defeats normal shooting on average shots.)Now, if it were your money, would you spend your money on CC’ing or on good lightning?
And that is just the image. Would you spend your money on a high end cam or on a good story?
Would you spend your money on gorgeous images but no time to edit them?I prefer a good movie on VHS over a bad one in IMAX.
Let’s agree to disagree.

While I can agree to disagree on the ultimate value of recording in log in certain cases, it is most certainly not a “hack.” It is a way of taking the enormous range of values in the real world and capturing it in an efficient manner. The real world exists as linear light, but your human vision system interprets that huge range of values by limiting the number of variations you can see in the brightest values and emphasizing the lower and midrange values that are more critical to interpreting the world you see. What that means is that the human vision system is logarithmic, just like the “hack” you’re talking about. When light is doubled – i.e., increased by one stop – your eyes and brain don’t see the result as being twice a bright. If one really wanted to record what a camera is actually seeing as absolutely as possible, one would always record in linear light (i.e., what the sensor actually sees). However, as with human vision, that isn’t practical or necessary. Log encoding is one way of approaching that problem, and applying a gamma curve is another. Log encoding has the very real advantage, though, of being much more efficient in its use of available values to better capture a wider range. In essence, the use of log encoding is no more of a hack than the human vision system is.

Mike,
You win, no questions asked.
Math over good shows, logic over entertainment. Arrogance over argument. (Trust me, on the last one it’s hard to beat me.)Bouke

It’s not binary choices. You can actually have proper craft and good material. You can have top quality images and a good story. You can have better approaches and simple ways to make it sing. All one has to do is want it.

Sure Mike, happiness / wealth / success / food / shelter, well, even health is a choice! And it all comes for free, without having to sacrifice one for the other.
Just tap your heels three times, and it will all come trough.Happy new year!

Nah, sorry, that was too harsh.
I do agree on large amounts of what you’re saying, and you misinterpret what I call ‘hack’.
But, you seem to live in a high end world and seem to forget what the majority of people have to face.
Small example, our biggest newspaper does videos now, and even they do NOT shoot in log and have proper white balanced / lighted / recorded, they still are able to annoy me with a video that fails in every aspect of the craft.
So, please, bear with me and do read what I write, and try to understand at least half of it.Again,
Happy new year!Bouke

>>Small example, our biggest newspaper does videos now
What’s a newspaper? 😉

An organisation that forces clueless people in this bizz that you have to educate for free so that in a few years you are out of job.
It might be less frightening, it may only be that news gets more annoying than it is right now, think of 30 minutes of video that tell you nothing but will make your ears, eyes and nose bleed. (This site is moderated, so I leave it to that.)Bouke
