Above is the first version - actually closer to the true colour of our very dirty oven door, but various edits later and a decision that the image was too warm and I have the result below. To produce the second result, I took the edited version of the above and saved as a TIFF, then brought it into Camera Raw and adjusted the colour temperature to cool it off a bit. I suspect that ideal will be somewhere between and it's clearly a work in progress. The journey has not finished.
and the last is a reshoot later in the day with less light from the front of the glass.
