Whether you're selling on eBay, creating a fine art print or fulfilling a commission from a client, the ability to shoot an object against a white background is really useful. It's also next to impossible to achieve with lighting alone! Here's how to finish the job in Photoshop.

Welcome to the tenth instalment in our 15-part series on how to fix common photo problems in Photoshop, Lightroom and Adobe Camera Raw.

We don't know how long the global coronavirus is going to last, but for those of us confined to home working, at least we can try to do something constructive with our time – and what could be more constructive than learning some new Photoshop techniques to rescue, repair and reinvigorate all those nearly-right photos in our back catalog?

In this instalment we'll show you how to hike up the highlights in Photoshop to make your product shots brilliant.

Photoshop dodging and burning

The high-key, white-backdrop look is ideal for product and portrait photos, but sometimes it can be tricky to get the background fully white in- camera. It’s easily fixed in Photoshop, though.

Duplicate the layer with Cmd/Ctrl+J, then grab the Dodge Tool. Set Range: Highlights in the tool options at the top, uncheck Protect Tones and press 1 for 10% Exposure strength. This allows you to paint over the whites to brighten them without affecting the rest of the tonal range, so you can brighten the backdrop.

If you’d like to check that the backdrop is 100% white, add a Curves Adjustment Layer and drag down on the curve line to temporarily darken the image to near- black, then highlight the layer below and continue dodging to fix any areas that have been missed.

Jargon buster

Dodge tool: This gets its name from the 'dodging' and 'burning' techniques used by darkroom workers to lighten or darken different regions of a print. The Photoshop version is much more sophisticated, with the ability to choose the tonal range affected (Shadows, Midtones, Highlights), the size of the brush and the strength of the effect.
