Effects Filters: What They Do and How To Use Them

OK now you know the basics of colour correction filters let’s talk a little about effects filters. These differ from colour correction filters in that they are designed to create a specific mood when lighting a scene.

Now before we begin I just want to get something off my chest: a lot can be, and is done, in the grading stages of production to help bring out a visual style of a film/documentary BUT – it’s important to remember that lighting with a certain style in mind, i.e. lighting with purpose, will give you much greater results and much more to work with when you get into your grade.

effects_gels_thumbFor example: Want to enhance that backlight to make it bluer in the grade? If you’ve lit the scene with balanced “white light” you might find it hard to isolate the specific source you’re looking for. By having distinct colours in your raw footage it will allow you to select and enhance/desaturate elements quickly and easily in your grade. You can achieve this using gels or mixed colour temperatures. Make sense? Good. So let’s get to it.

In this blog I’ll show you three commonly  used gels to help:

i. Create Flattering Lighting
ii. Replicate Moonlight
iii. Replicate Sunset

Colour Correction Filters
How To Convert Daylight to Tungsten

OK, let’s do a quick review on colour correction so far; in my first blog in this series we’ve talked about the importance of colour temperature, how it’s measured and how that relates in terms of the colour or hue of light. Warm looking light has a low colour temperature and cold looking light has a higher colour temperature. We’ve said that the colour temperature of natural daylight is 5,600K but changes throughout the day and we’ve now talked about how to convert (or correct) tungsten light into daylight using specific blue colour temperature gels know as CTB gels. Now I want to move on and discuss HMI’s (these produce daylight) and how we can convert them into Tungsten light or give the HMI light a warmer look.

Colour Correction Filters
How To Convert Tungsten to Daylight

Hello everybody. First of all, as I’m sure you’re aware, I’ve not posted a blog in quite a while. I must apologise but I’ve been incredibly busy over the past few weeks (filming left, right and centre), but I’ve had a bit of time recently so thought I’d continue with the series! Hope you guys enjoy it, be sure to leave a comment or get in touch on facebook/twitter!

Ok so this is the second blog all about colour correction, if you haven’t read the first one, here it is . If you have read the first one I hope you now have a very basic understanding of Colour Temperature. So, where do we go from here? Well there are two forms of colour correction, colour correction in camera (known as White Balance) and colour correction in lighting.

Colour correction in camera is something we’ll discuss another time, for now let’s concentrate on Colour Correction in lighting.

Daylight Colour Correction

First things first. Basically there are 3 types of lights that we use in the film and TV industry: LED, Tungsten and HMI Lighting.

LED lighting will be covered in a separate blog but for now I want you to explain the difference between Tungsten and HMI Lighting, before I go on to look at how we  convert Tungsten light into daylight…
