Lighting Revolution
This long exposure technique is far from new and I was doing something similar to this 25 years ago at art college. However, in previous years I would use a studio strobe to flash, but then I’d need an alternative light to produce the ambient light. Historically these were always tungsten lights and they were a real pain to use. In case you aren’t aware, the old tungsten lights produced light by passing a current through one of the strongest metals available to us, tungsten. The current passing through this metal would literally make the metal glow bright orange and this is what created the illumination. This seems simple enough and we used tungsten lights for many, many years, but there were significant downsides to these lights. Firstly, if you’re passing power through metal with enough force to make it glow extremely bright, that metal is going to be extremely hot as a byproduct. This made operating these lights a nightmare for obvious reasons, but the other major issue of super-heated metal is its bright orange glow!
Remember that this orange glow is very different to the cool blue tone of flash, so to make these ambient lights look good in shot alongside flash, you’d often have to neutralise that orange colour like you see me doing in the shots above. This meant placing colour-balancing coloured gels (thin sheets of plastic) in front of the lights. As you may well imagine, these sheets melted extremely quickly and were just a pain to work with for extended periods.
Are you starting to see why long-exposure studio photography isn’t very popular yet?
LED Revolution
Unless you’re relatively new to planet Earth, you’ll likely be aware that LED lighting has been dominating the photography scene for a while now. Sure, flash still has its place, but LEDs bring an awful lot of convenience to the table and especially when it comes to long-exposure photography.
Firstly, LEDs are infinitely cooler to run than tungsten and you can have a decently powered LED on for hours and it still be cool enough to touch. Secondly, seeing as you’re not forcing lightning bolts along thin strips of metal, you’re no longer producing bright orange light as a result. Just these two things alone now make long exposure photography a breeze, but there are yet more benefits to be had with the right lights.
Rotolight and RGB
For the last year or so I’ve been using the new Rotolight LEDs and as someone who uses an awful lot of colour in their photography, these lights are a dream-come-true. Why? Because the Rotolight LEDs can offer me a full 16 million colour RGB spectrum at the twist of a dial! So now I have cool running lights that won’t give me third-degree proxy burns AND they aren’t producing an egressive orange glow that would make a TOWIE girl blush in the process!
Are you starting to see why this will make our long exposure life extremely easy now?
But wait, there’s more…
Ordinarily, most people purchase LED lights to escape the nightmares and difficulty that flash can provide. But if we want to shoot some cool-looking long-exposure portraits, sadly we still have to use flash to freeze the subject. Once again Rotolight has us covered though as not only do their lights provide full RGB spectrum ambient lights, but those same lights can flash in the full RGB spectrum too! To my knowledge, I think this is the only LED light on the market to actually flash in any colour you want.
Now look, I appreciate this sounds like I’m overly gushing over these lights and although I’d ordinarily let our American counterparts do the uncouth work of telling you that these lights are ‘the greatest things ever made and you need to buy them immediately’, let me put my British stoicism on hold for a moment and just add that these lights are quite simply ‘lighting on easy-mode’!
If you’ve ever fused flesh-to-bulb or melted a box of gels on tungsten lights in the past (firstly, welcome to being old like me), then you’ll appreciate just how easy these LED lights make your life today. So yes, I’m very impressed with these lights, but you have to also remember what we had to use in the past. You young-uns don’t know how easy you’ve got it!
Many of you have been following my work on here for over a decade and in that time you’ve seen me working with all manner of lights. When I originally started working with these Rotolights over a year ago, I actually had no intention of completely dropping my old studio strobes….. but truth-be-told, I barely use them anymore.
