As I mentioned in my previous post the overall exposure of the subject is okay but the light trails from the flashguns power LED presented a problem. I could have avoided this by taping it up but this is the first time I've encountered such a problem but it's a lesson learnt.
The key to getting these 2 images identical was using a tripod and mirror lock up to minimalise the change of camera shake meaning the images wouldn't line up in post. Once they were both in the same window in photoshop I created a layer mask and simply painted in the car and any other areas I wanted lit up eg. the floor.
Overall I'm very happy with this photo and it wouldn't have been as easy to achieve if I hadn't have used a slow shutter speed because I would have had to use at least 4/5 lights to expose the subject more than the background and then remove the stands in post production etc.
This is a very popular technique used in car photography as the dynamic lighting gives the car a much needed edge in comparison to most photos in natural light.
I also been experimenting with light painting as this uses a long shutter speed and a light source.
I used a glass bottle as this lets like through and gave interesting results. I placed my camera onto a tripod and set my exposure at 10sec, f16, ISO 100 and focused onto the centre of the bottle. I then turned off all the lights and used a torch to literally paint the bottle with light.
As you can see the bottle is much brighter than the background because I was moving a torch around it. In some shots you can see streaks of light behind the bottle, this is where the torch was facing directly at the camera similar to when people light paint words. I like this technique and it helps me understand long shutter speeds and how to use light with it.
