Is this art?

What is art? Who decides? This image was inspired by those questions. I obviously need to get out more!

This image combines an existing picture frame hanging on the wall with a dust sheet I’d used to protect surfaces when painting various things. Arranging the sheet was the hardest part of the composition (once I'd had the creative idea). I wanted to create a similar effect with the folds to that seen in Dutch 'still-life' paintings where you feel you can almost touch them. So I organised the lighting to accentuate the texture and folds of the sheet - very diffuse ambient light from two windows with translucent curtains, direct frontal flash from the camera's built in flash gun and side lighting from an off-camera flash set at about 45° to the subject matter. The exposure was 1/125 sec, f2.8, ISO 100.

There’s an extra dimension to the image for me. Each paint stain on the sheet is a memory. They were created randomly as I used the sheet at different times with no intention for it ever to be more than a dust sheet and yet somehow the colours and shapes work well together. So the dust sheet represents more than a random pattern of colours and shapes. It’s a collection of memories, whether it was the day I painted umbrella stands blue around the pool, renovated tables and chairs on the porch with a mahogany wood stain or looking over the valley to the mountains as I protected the pergola on the balcony with ebony wood stain.

Is this art? For me, yes but for someone else it might just be an old dust sheet.
