Nice images! I'm not familiar with a Rotolight. I'm assuming it supports high speed sync with the shutter speed you used in the images with Christmas lights? Can you please explain a little more about those images?
By the way, also nice with the LED string lights. I read an article recently that mentioned the flicker rate of LED string lights and the problems it poses getting good shots.
Thankyou
So I work for Rotolight so I have a bit of a better idea of how they work lol
They are an LED light first and foremost but it also can be a HSS, No recycle time flash as we can overpower the LED's for a split second and not damage them, this will give us the ability to get another stop of light out of them.
These were actually taken in LED mode on 100% which means I didn't have to worry about sync times etc.
I had the Rotolight NEO 2 behind a shoot through umbrella and then had a silver reflector below, see image below -
On the fairy lights, I have never had an issue with the flicker from them at any frame rate, but I can see why that may be an issue. For the Rotolight products, they are completely flicker free
The obvious advantage of the Constant light of the Rotolight is the shoot what you see scenario, I dont need to worry about flash etc. Also I can expose the camera for the model and as it isnt a harsh flash, the Fairy lights are still prominent
The other part of it, because I was hosting a workshop I was able to use LED mode and get through people shooting without worrying about them having to have transmitters on the camera.
