Color analysis request

This page offers an online analysis service for your pictures.

Conditions

◦ format : jpg / jpeg
◦ maximum file size : 6 megabytes
◦ maximum number of pixels : 12,000,000
◦ minimum number of pixels : 1,000

Precautionary measures

Uploading large files takes a long time (typically 3 seconds per megabyte in xDSL or 4G) ; it is therefore advisable to resample the picture to reduce it to less than 500 kilobytes. The analysis is very little affected.
It is advisable to crop the picture to remove the degraded or poorly lit parts (edges of the painting e.g.), and if necessary to revive the colors by means of photo editing software (which often compensates for a poor lighting or aging of varnishes).

Procedure

Select the jpg/jpeg file to upload and click on SEND PICTURE.
