Low light pictures in an arcade are hard to pull off – you have a choice between using a flash, a very fast lens, or a high ISO setting on the camera. All have disadvantages – using a flash gives that harsh ‘flash’ look (unless done carefully). A fast lens (like f/1.8) is good, but you have low depth of field. And.. unless you’ve got one of the modern generation of cameras, high ISO will give you a really ‘noisy’ shot.
In this case – since I didn’t want to use flash, I used my 50mm f/1.8 wide open to let in as much light as possible. I also juiced the ISO up to 3200 – which is very usable on the 5D Mark II.
