In Topic: Red filters for GH4

25 April 2016 - 03:27 PM

Thanks guys. Since I'll use the filter just in specific situations I think all the options seem to be a little bit messy, so I guess the right way to go is first use the filter in the 12-35mm. If it works fine, I'll return to this topic.

Magic filter is good, I have used it a lot and it definitely help when getting deep, you do lose a stop of light. If the lens doesn't have thread, you still can use it, look at the instruction here:

I wrote to Alex and he replied that he is not sure none of his rear lens filters would fit in the  Pana 7-14mm. Let's see if someone comes up with a solution...

 

 

Also, unless you really need 4K, then I'd be inclined to shoot Full HD at 100Mbps instead. Whilst it's possible to supersample 4K to Full HD to improve quality, you're still reliant on decent source footage at the 4K end. Shifting to Full HD @ 100 Mbps, you're effectively reducing compression by a factor of four... the more compression you have, the more you'll see noise and issues in the low lights, so this is going to help.

 

Just ideas and suggestions....

Ups!. Well. That is the theory. And that was the main reason I never considered buying anything to shoot in 4K at all at first, but after reading a lots o reviews articles it seemed that 4k postpo and grading and downscaling from to HD actually gives better results than shooting and post-producing directly in HD.
The argument basically is based on the fact that the 4k compression algorithm is much more effective than the HD one.... but I don't remember well the details, I ended up dizzy from so much research.  
 If I tell you the truth I haven't had the chance to test it myself... but I will!

"I do so with the purpose of being convinced rather than be convincing"

 

For somebody who doesn't speak English as a first language, you have a wonderful way with words. I may borrow the above on occasion, if you don't mind!

 

I would be really proud!!!!
I wish my sophomore english teacher could see this... :laugh:

I totally agree with you. I never tried to deny the obvious effects of different shutter speeds. I just try to reframe the apparent need for setting up something as "the normal thing". I think don't waste time when arguing... I learn a lot. I do so with the purpose of being convinced rather than be convincing. Thanks :)

Sorry, I forgot to answer those questions.
I was shooting mov files 4K(100Mbps), 25fps (3840x2160). Iso 1600. (as I said much more noisier with my second MWB than with the first)
Regarding shooting subjects 4m away.... At night I can get by with my two Sola 2000 lights in some situations. But in daytime, I always try to avoid using lights for subjects further than 1 meter because of the issues of mixing lights of different color temperatures. My very first term can be lighted with my Solas and a do the MWB for them. But at 3 meters my lights loose a lot of their influence and getting the right light filtering with nice results is really hard.
