Three wine glasses that have been lined up. The front one is empty, the middle one is half filled with water and the back one is filled with water. A few drops of green and blue food colouring and I get this shot.
The glasses are back lit and I separately lit the table that they were sitting on. The two images were then blended in post.
The waves in the glass are due to imperfections from the glass manufacturing process.
This is one image where I notice a significant difference between the sRGB and AdobeRGB screens. The gamut of 100% sRGB screens does not show off the greens and blues nearly as well at the 100% Adobe RGB ones. On the sRGB screens the greens and cyans are quite dull on the Adobe RGB screen, the greens and cyans are very deep and vibrant.
