Last week, I attended a conference on Chroma key ফটোগ্রাফি where I found that almost all aspiring green screen photographers are too nervous about using their Chroma key kit. They were asking all silly প্রশ্ন such as which backdrop stands to buy and what types of lighting should they use. I admire Mr. Jackson, Mr. Cameron and others for listening to them patiently and answering each of these questions. Even after getting beautiful and detailed explanation, I could still see nervousness on their faces. At last, I couldn’t resist and after the seminar was over, I called a bunch of nervous photographers and ask them what makes them fear their photography backdrop stands অথবা the green screen software?

Chroma key ফটোগ্রাফি is not a rocket science but most photographers, who have never tried their hands on it, think that আপনি need a lot of training অথবা perhaps a special course. If আপনি can undertake training, it will be easier for আপনি to do the background replacement but আপনি can achieve fairly good results even if আপনি do it yourself. I learnt it দ্বারা referring to the tutorials available on YouTube and various other ফটোগ্রাফি sites.
The bunch of people whom I was talking was delighted to hear that there are no secret formulas for green screen photography. All আপনি need to do is to get a good quality green screen backdrop, backdrop stand, and specialized green screen software. If আপনি are a photographer, আপনি might be already having the lighting accessories. Here are some key points that আপনি need to keep in mind for Chroma key photography.

1. Light the foreground as well as the background separately. আপনি can do this দ্বারা backlighting your subject. This will help আপনি to easily subtract the green background and add your desired one.

2. Ensure that the backdrop falls seamless from the photography backdrop stand so that there are no wrinkles. আপনি can even use clamps to make your background smooth. Creases can make background separation difficult.

3. If আপনি are using a green screen, make sure there is nothing green in the background. This rule also applies to blue screen. If আপনি have the background color in the foreground, it will also be replaced during Chroma keying. For example, if your model is wearing a blue tie that matches with the background, while editing, the tie will also be subtracted.

4. Use all the usual ফটোগ্রাফি rules such as diffusing the light, three-point lighting system, etc.

5. Keep experimenting to come up with your own rules.

Chroma keying is so easy that anyone with basic ফটোগ্রাফি skills will be able to do it. If আপনি are one of those people who are anxious about Chroma keying, stop worrying and start practicing.
