EDIT THE SHOT
1 REVIEW YOUR IMAGES
Import your product images into Lightroom and view them all in grid view to assess the lighting style in each frame. By changing the light position while shooting on a tripod, you will have the same composition but with multiple light directions.
2 RETOUCH THE PRODUCT
Select a base frame that has minimal reflections in essential areas, such as the watch face. Make tonal adjustments, then use the Spot Removal tool in Lightroom or the Spot Healing tool in Photoshop to remove dust and scratches.
3 COMPOSITE LIGHTING
The shot with the ideal lighting for the top of the watch has too much of a highlight on the face. This area is therefore selected from another frame using the Pen tool (P) and composited on the base image, which has a better reflection and tonal range.
4 ADD THE WATER
Create a new Photoshop document, fill it with black, convert the plastic wrap image to monochrome, and drag it onto the new background. Change the blend mode to Screen. Use Distort (Image > Transform > Distort) to place the texture at the top of the frame.
5 BLEND THE WATER EFFECT
Colour the plastic effect to make it appear like the surface of an ocean. Use Layer > New Adjustment Layer > Hue/Saturation. Check Colorize and select a blue colour. Add a mask to the plastic layer, and use a Radial Gradient to fade the edges.
6 FINISH THE COMPOSITE
Drag the watch image onto the background document, add a layer mask, and erase any peripheral detail. Using a soft brush, add some colourful watery mist to fill space. To simulate filtering light, click several times with a brush on a new layer and use Motion Blur.
