Pour a shot
This technique is brilliant for creative wedding shots too
01 Raise a glass – or several!
Set your camera up on a tripod and position the glasses in front of it. Think about how you want the background to look when it’s flipped upside down. We wanted to make our subject stand out really clearly, so positioning them in front of a bright area such as a window was ideal.
02 Line ’em up
You need a lens that will allow you to get close to the glasses. A macro lens is ideal, but a long zoom with close focusing will work as well. Experiment with the position of the glasses and any other items, such as the green bottle here. Even minute adjustments can have a big effect on the scene.
03 Set a narrow aperture
With objects close to the camera, depth of field can be very shallow, so if you want detail in the foreground and background a narrow aperture is essential. This will probably mean compensating with longer shutter speeds and/or higher ISOs. We set ⅓ sec at f/18 and ISO800 here.
04 Check what you’re getting
Live View focusing is ideal for situations like this where, due to the layers of transparency in the image, the AF may snap on to the wrong thing. Switch Live View on, press the zoom button once or twice and use the joystick to move to the area you want sharp. Fine-tune the focus manually.
05 Pose and shoot
Whatever is behind the liquid will appear flipped upside-down. If you have a person to help you out, ask them to pose so that their body shape is easily defined against the background. Move them closer or further from the glasses to see the effect the distortion has on the body shape.
06 Spot check
No matter how much you scrub the glasses, it’s difficult to get them perfectly clean, so you might need to tidy up smears with Photoshop’s Clone and Spot Healing tools. Go to Layer>New, then set the tools to ‘Sample: All Layers’ in the options to keep the changes non-destructive.
