Beverage and packaged foods are often made up of several materials that react to studio lighting differently, which results in reflections. Take an artisan sauce for instance, which is usually contained within a clear glass bottle (with curved and straight surfaces) filled with a viscous liquid (causing the light to bounce back at many different angles) incorporating a glossy printed label (sometimes with metallic writing) and often topped off with a black or shiny metal cap. With packshot photography compounding these issues is any additional outer packaging that the product container may come in and props used in the photo shoot.
Not for the faint-hearted and certainly not for a photographer with little experience in such matters. Tim Salix has over time created methods and obtained materials to overcome such hurdles.
Once photographed products are cutout in post-production to create a transparent background using vector tools in Photoshop that ensures a precise edge essential for placement onto coloured backgrounds or for print. A cost-effective alternative is to photograph in-camera to a white background. For businesses needing a high volume of photos this may be a viable option.
