GH2 WHICH LENS for each shot?

ISSUE 3:


images

I'm gonna attempt some green screen with this cam. Shot wise it could be any of the shots in the 4 pic. However a FULL shot
, Portrait Head to Foot will be needed {see green pic}

Now with my minimal lighting kit on hand, lighting both subject and screen is gonna be very tricky. In that event I'm wondering if the 20mm 1.7 is the right lens for that?

PS - I guess the Flow Motion 2 is a good hack to start for green screen? Or does Driftwood have a preferred hack for this?

thanks

Hello,

back to my GH friends here!

------------------------------------------

SAGE SAID

Working with those choices, I would absolutely light, with soft diffused sources over the characters, and shoot everything in the 24/30/35 range. (Tendency toward 30/35/40 for non action like this, 24 for action). And you'll get a decent f stop in the 4 range.

Ok, great suggestions, thanks Sage


SAGE SAID

40 on the long for epic scale, and 30 in close for a sense of potential aggression/immediacy

Interesting.

thanks

Start with three lenses.

-a normal

-a wide-angle (roughly) twice as wide

-a telephoto (roughly) twice as long.

ok, thanks Ben. Sounds like good advice.

I know the canon FD 50mm is recommended, but is anyone using the Canon EF 50mm f/1.8 ?

I know this needs an adapter, but does that make it good? thanks
 
Your biggest problem with the EF mount one is that you'll have no aperture control, as there's no Aperture ring on it (it's all electronically controlled). This means you'll need an adapter with an aperture in it, which is much more expensive. You can also probably find the FD lens for cheaper than the EF lens.

thanks IronicCatfish.

Thats a bummer. I may get the FD later, but I'm now thinking Nikon lenses work better with the GH2.

Thanks Bob, I have been searching, but Im just a beginner here and its very confusing. what I'm posting now, I couldn't find in any search.

eg . No mention of green screen with flow motion 2 . did I just miss it in a search?

I asked about that lens on here awhile ago but I don't think anybody uses it. In theory it should be a good lens since you can control the aperture with it. It is a newer generation lens so may look a bit sharper then some vintage lens options. Outside of those obvious facts I couldn't tell you how well it will work. I wanted to get one as an alternative to the Olympus 45mm f1.8 since it is a heck of a lot cheaper.

Checked out some reviews based on actually using it on a Nikon camera and it seems like an ok lens. Not great but not a fuzzy vintage FD lens either. The Olympus from what I can tell is still much sharper and rich although good luck finding a side by side.

The hack is not important. Just that it is hacked, as higher bitrate will help the key.
Just look for greenscreen work for the GH2, or for 4.2.0 colour space.
 
Thanks Thomas Smet,

for reply. Yes I read some great reviews (user} on it actually. { and I did find your initial inquiry if anyone wonders if i search, btw }.

The reason I'm picking some of these newer lens choices - versus Vintage lenses is:

1. sometimes price
2 shipping: I need fast shipping, and many of the vintage are standard ship.


thanks

Yes, I plan to go with a high bit rate hack for it. { Although - I've never hacked yet - so this may sound
a bit foolhardy! . Although I did order a fast card in preparation. }

I was just wondering if anyone had tried flowmotion 2 for green screen? , since the inventor describes
it in special terms. Or if there was a preferred hack solution?

thanks

Whats the best diffusion material to throw over a hot home depot type light, anyone?

Diffusion is up to you. I would get a Lee Filters diffusion pack, and possibly a master collection pack to get you started on using diffusion and color in the camera. The shop lights I believe you're talking about typically run closer to 2800k in color temperature and need a sheet of 1/4CTB (blue gel) to correct to the camera's tungsten setting. When I used to use the shop lights, I'd always build a gel frame out of wire clothes hangers to keep meltable gels off of any surface not designed for it. Also look into some Rosco cine-foil/blackwrap to make makeshift barndoors to shape your light, cut your light, etc. It's also good to cut off spill that isn't being filtered through your gels.

Now, you can use an opal frost sheet of diff to get a little bit of softness while keeping most of your shadow/shape. You can use a sheet of 216 diff to get a much softer light. Or, you can screw the diffusion on the frame altogether and bounce your light against a 4x4 sheet of foamcore from the art supply store. You can spray-paint a side of that foamcore silver and bounce it to get another different quality of light. Hell you can set a sheet of sheer curtain a few feet in front of the light using another sheet of diffusion on the light itself.

Researching this on the internet is a good idea, but it's much more fun to get off the computer and test it out. Get your camera!

Also I don't mean to sound snotty, but don't worry about which hack is better than another hack. This is probably one of the last things that will improve the quality of your camerawork. In this case of greenscreens, the most important thing for keying will be your lighting. Then you're limited by the color depth that the GH2 and most DSLR's offer. THEN you're limited by the bitrates. Maybe.

Great discussion. I'm new to all this as well and these posts really help.

Hypothetically speaking, couldn't you use say the panny 20mm for ALL shots and simply crop to achieve shots 3 (two shot) and 4 (head shot)? Particularly when shooting in 1080p?

Would the degradation in pixels be too significant to render a usable image?

You would never crop into a shot (unless you were working on a 5k camera and only needed to deliver 2k, so some reframing is acceptable.
 
Thanks mondayc for this great lighting post. This is sticky quality!

> okay cool. I doubt I can get fast ship on that, so for the future. { anyone know fast ship? Link?}

but I guess there comin on a slow boat from you know where. {anyone know overnite ship? }

Its on the way brother!

Oh yeah, Im getting a BMC which should take care of most these problems.

Ive got to teach my GH2 to sing!

But what if the only viewing medium will be the web? I keep hearing that it's acceptable to blow up to 25%, and in some cases up to 50% as long as you cut in 720.
