Digital Lens Optimizer

The Digital Lens Optimizer function enables the resolution of images to be increased by removing any remaining aberration related to image-forming capability or any deterioration of resolution resulting from diffraction phenomena. These optical phenomena cannot be corrected under Lens aberration correction. Correction is achieved using the designed value of each lens. The images that can be corrected are RAW images shot using any of the compatible lenses and cameras.

JPEG, TIFF, S-RAW, and M-RAW images cannot be corrected. To use this function, [Lens data] for the lens used to shoot images first needs to be downloaded to your computer. Before using the Digital Lens Optimizer, it is recommended that you set [Sharpness] or [Strength] for [Unsharp mask] for images to 0.

Caution

To use this function, an environment with Internet access (subscription to a provider, browser software installed and an in-place line connection) is required.

An administrator-level privilege is required for this operation.

Depending on the type, current state, etc. of software running on your computer, the download of the lens data may fail. If it occurs, wait for a while then try downloading the data again.

Since the lens data downloaded with Digital Photo Professional Ver.3.x is not compatible with Digital Photo Professional Ver.4.x, the lens data must be downloaded again.
