I have a 100% portable location studio kit that I can pack up on my Harley Davidson and ride to your place.
Yes, I am trying to work the image of the Harley Davidson Riding Cat Photographer.
Even though I have flash equipment I try to avoid using it as cats, in particular do not like the popping of the flash. It is too bright for their sensitive eyes and the sudden pop of light can startle them. This is not great when dealing with a shy animal.
My goal is to use only available light, so please open all those curtains.
