For all my work, I am using a digital camera. I have chosen to do this for ease of editing where the images are in a format that is Photoshop compatible. This allows me to edit various components of my work.
Film photography takes time to develop and I am limited by the amount of images I can take on a film roll. SD cards allows me to instantly review my images, deleting any photos that did not fit my aims for the shoot.
Although my work would be more suited to either a 10X8 large format photography or a film camera, I do believe using a digital camera is more efficient for my work.
