School today. We had to practise photographing a bottle. This is my result, a 10 year old port wine. Not completely happy with it, but I think it's reasonable.
You did a good job on the bottle, and the port is a beautiful color. The glass needs washing. I dusted my monitor to see if the dirt was on my side, but I think it's in the image.
Looks like a white port Henk. Guess you didn't get to drink it, otherwise the glass would have been half full - or is that half empty??? Maybe a tad higher f stop or a lower POV to get the bottom of the bottle and glass in focus. JMO
