It’s all in the lighting and the angles.
Photographing glass, such as wine glasses, can be a challenge. Often the results are less than satisfactory as the image below illustrates.
Adjusting the lighting position and the background and understanding the angle of incidence and the angle of reflectance can give a better representation of the glass as these next photographs show.
Photographed with a pretty ancient camera (in digital terms). It’s 9 years old, with a 10 year old digital back, but the sensor is huge, and an equally old manual focus lens (what no autofocus?!?) The lighting was even more “obsolete.” I used a 22 year old flash, the Nikon SB-25, in manual mode, with a cord attaching it to the PhaseOne. Your smartphone has a more sophisticated and faster processor than what I was using. Interesting, eh?
