Product Photography Post-Processing and Retouching 4

Question 1

What is 'focus stacking' and when is it used in product post-processing?

Accepted Answer

Combining multiple images focused at different depths to produce a fully sharp composite

Answer

Focus stacking merges images with different focus points to create a single image with front-to-back sharpness beyond what a single shot can achieve.

Question 2

In Photoshop, what does converting a layer to a Smart Object accomplish during product retouching?

Accepted Answer

It allows filters and transformations to be applied non-destructively and re-edited at any time

Answer

Smart Objects preserve the original pixel data, making all applied filters and transformations editable and reversible.

Question 3

Which masking technique in Photoshop is best for isolating a product with fine transparent edges, such as a glass bottle?

Accepted Answer

Channels-based masking using the high-contrast channel as a selection base

Answer

Channels-based masking leverages natural luminance contrast to preserve semi-transparent areas like glass edges that other tools miss.

Question 4

What is the purpose of a 'clipping mask' in a Photoshop product retouch workflow?

Accepted Answer

It restricts an adjustment layer or texture to affect only the layer directly below it

Answer

A clipping mask confines the effect of one layer to the shape and transparency of the layer beneath it, enabling targeted adjustments.

Question 5

When retouching jewelry product images, what technique is commonly used to enhance the sparkle of diamonds or gemstones?

Accepted Answer

Painting star-shaped catch lights on a new layer using a sparkle brush set to Screen or Add mode

Answer

Painting sparkle catch lights on a Screen-mode layer adds controlled glints that mimic real light reflection without destructively altering the gem.
