Hi everyone! I currently live in Milan and I'm working on a project that involves a huge green screen. We need to convert a room of 26x13 ft. into a green screen studio. I was doing some research online, looking for paintings to use, and I found two main brands of green screen paintings: ROSCO (US) and HATO (Germany). There is a very big difference of prizing between them and I was wondering if you could help me understand why? For example, in amazon.it you can find one gallon of ROSCO for 320EUR (. The gallon of HATO paintings costs around 92EUR. I don't know if this is because HATO is made in Germany and is near Italy so it costs less? Do you know any about quality differences between this two types of paintings? Do you recommend something specific? Maybe another brand that I didn't find on my research? If you have any advices on how to paint the room in order to make it work perfectly I would really appreciate it! Thanks!!
2x IRND = green ?
christian mann posted a topic in AC's & DIT'sHey, so I was wondering if it's now true that when you use 2 IRND picture will turn green... If one IRND blocks Infrared light shouldn't there be "no more" Infrared light left the be blocked for the 2nd IRND? Why would the 2nd IRND filter have an effect on the image if the Infrared has already been blocked? Does the IRND have a green layer that blocks the Infrared and hence will turn the image green when using 2 IRNDs or how excactly does an IRND work? I've seen some DoPs using 2 IRND without any hesitation, others don't... What's your take on it? Thanx
LED Lighting cool white vs warm white
Freya Black posted a topic in LightingWell I've just had a bit of a shock. I bought some LED light bulbs and normally I get cool white bulbs but this time I bought some warm white as they were on sale and there wasn't a choice. However on getting them I was shocked at how green the output was! It was immediately visible and was much worse than on other lights I have encountered even with flo's. Of the bulbs I bought the little candle style bulbs seemed the worst. The bulb shaped bulbs were still bad however. I put one of the candle style bulbs into a lamp with a shade all around and it lit up quite green and with the addition of some orange gel it became quite bright yellow like you might find in a highlighter pen! Is it the case that warm white is a lot, lot less colour accurate than cool white? The cool white bulbs look a bit blue but I've generally had good experiences with them. I think I will avoid warm white in the future unless it's for a special effect! Freya
Hello, I have done projects on and off over the years with chroma key using amateur tools like work lamps for lighting and Jo-Ann fabrics for the green screen. The results were less than ideal but worked well enough to produce the desired effect. Coming up now is a project involving green-screening the entire exterior of cars, top to bottom, front to back. Because of the requirements, I am now looking to buy plentiful amount of green screen fabric in order to cover what is required for a full-size car or truck. I have read through some of the threads here on cinematography.com and found good info concerning chroma keying and its idiosyncrasies. I had no idea that video encoding and picture resolution had such varied effects on the success of the key. That brings me to my questions. I will be using a Sony HDR-CX300 Handycam for most of the shooting. From what I understand the video encoding it uses is AVCHD. What are some suggestions I should follow towards making the chroma keying more effective when it comes to processing the video? And I also plan on using green fabrics from my local crafts store to provide for the green screen. I will most likely rig them up to an outdoor setup using PVC or the like. Apart from wind and sun, are there any other obstacles that may arise from using this cheaper alternative of green screen? Thanks in advance, Adnan
