What is a Polyboard?

Polyboards are large sheets of foam that are traditionally used as insulation in building construction. As most studio photographers know, they are also great as light modifiers. Most photographers use white and black polyboards to reflect light and create shadows.

Polyboards are large sheets of foam that are traditionally used as insulation in building construction. As most studio photographers know, they are also great as light modifiers. Most photographers use white and black polyboards to reflect light and create shadows. They are lightweight, cheap, and have a large surface area. For my studio, I decided I wanted many polyboards of different colours to use as backdrops and reflectors. To create coloured backgrounds in studios, photographers often use gels on speedlites and strobes to light up a white background. I have found this can work fine, but it can also take a bit of stuffing about getting an even and consistent spread of colour. The advantage of using gels is that you can get a larger spread of colour than a polyboard provides. But a polyboard will have a more consistent, richer colour. There are several companies around any major city where you can find polyboards. The standard studio photography size of these is 2400mm by 1200mm and a 50mm thickness. I went for 75mm thick, as I wanted something a little more rigid. Keep in mind that the size you choose will determine the size of stands you need to construct. If you are having the boards delivered, I recommend you make a special note to the provider to deliver them mark and dent free. Since they are usually used in construction, care is not usually taken with them, and I had to have some replaced.

Painting

Each side of a polyboard uses between 350 and 500mL of paint—you will generally need two coats, but it depends on the colour. Most paint retailers will mix up a one litre tin of an endless array of colours for about $30. To get the best finish, I found a grey undercoat makes for a much better end result. Adding an undercoat additive to white paint will give you undercoat. A small roller works better than a brush. Not all colours are available in a matte paint, but low sheen works just as good. I used outdoor paint, which is a few dollars cheaper and works fine. Make sure you reserve a board and paint for black and white reversible colours on the same polyboard (one side black, one side white). This will allow you to quickly reverse them without grabbing another board, as is often needed. Black and white are used most as light modifiers.

It’s best to have your stands specially welded and powder coated. I got mine without a powder coat—but I found the raw steel not only looks ugly but marks the polyboards, so I got a panel beater to powder coat them for me.

Shooting and Practice

I have tried many lenses and lighting setups using our polyboards and I have found a long lens works best—this will give the maximum amount of subject viewable on the polyboard without the frame extending beyond the edges of the board. This means that the more space you have in your studio and the further away from you subject you can get, the better. Having my studio in an open grey concrete slab warehouse, the coloured polyboards also give the studio a lot of life. Whilst the coloured polyboards give a fabulous rich coloured background, I am finding the black polyboards absolutely indispensable for creating shadow and deadening light. I seem to rarely take a shot without surrounding my subject with these. I have also found the slightly rough bubbled surface of foam can show up too much in a shot depending on your lighting. It’s generally a quick fix in post to smooth and blur these out. Overall, my polyboards have been a well worthy investment and have given my studio a unique feature.

Cost

Polyboards (2400mm x 1200mm & 75mm thick ): $45 + delivery

$45 + delivery Paint : approximately $30 per litre

: approximately $30 per litre Stands (with white powder coating): approximately $85 each

approximately $85 each Models: priceless

So the total cost of each polyboard with different coloured paint on each side is about $165.
