Well for starter: 99.99% I do not use artificial light when I photograph interiors. Now if that's a good and effective technique to shoot or not, that's a different question. But definitely what I do when I shoot works really well with my post production technique. I basically do a series of exposures from under expose to overexpose and then I blend them in photoshop. Now, how do I blend them, that is trade secret. But I will tell you this much, the result is close to reality as possible and does not sacrafice the lighting intent of the client's.
