When feathering an area of interest, if the resolution exceeds 1500 PPI, by how much should you multiply the number of hundreds?

The correct answer is based on the principles of image resolution and how feathering or blurring occurs in digital photography. Feathering is a technique used to create a smooth transition between an area of interest and the rest of the image, which often involves manipulating the resolution.

When the resolution exceeds 1500 PPI (pixels per inch), it is typically recommended to multiply the number of hundreds by a factor of 4. This multiplier accounts for the increased density of pixels, allowing for smoother transitions and less pixelation in the feathered area. Higher resolutions mean that each pixel represents a smaller part of the image, so greater adjustments are necessary to maintain quality and effectiveness when applying feathering techniques.

In lower resolution settings, the feathering effect can achieve adequate results with less adjustment. However, at resolutions exceeding 1500 PPI, the density and detail require more significant multipliers to preserve the visual integrity of the feathered transitions, which is where the factor of 4 becomes crucial. This understanding of resolution and its relationship with feathering helps in achieving optimal outcomes in photographic practices.
