Digital Treasure Trove: Post-Production Photography Editing

Contributed by PAFA Museum Collections

As part of our ongoing IMLS grant project to digitize portions of our collection, we are continuing to photograph works in our collection, but we are also beginning to process and edit some of these new images in preparation for their integration into PAFA’s databases.

If you have followed the Museum’s previous digitization initiatives, then you should know that these efforts are resource intensive. It is important that we take the time to digitally capture works of art that represent our collection as true-to-life as possible. To ensure we obtain high quality digital assets, there are two points in the digitization workflow that we focus on: 1. the moment we take the photo 2. the post-production work done after digital capture. For paintings and works on paper, this can be as simple as adjusting for the amount and color of the light, ensuring the work is square to the lens, and cropping as needed. For sculptures and 3-dimensional works, however, there are many additional variables that need addressing, including the consistency of the gradient background.

In a perfect world, the background would appear perfectly consistent across our hundreds of images, but this is not always the case. Often when shooting the images, the accuracy of the represented object must be prioritized over the look of the background, leaving artifacts in the image like folds in the paper or markings from other sculptures. To address this, we must correct these issues in post-production.

For every individual image that requires this correcting, we must break them down into three separate Photoshop layers: (1) an isolated background without the object (2) a copy of this isolated background without the object that has had a gaussian blur applied to it (3) a top layer that has only the isolated object. These layers are then carefully stitched together in such a way that the distractions of the “imperfect” background are fixed, while preserving all the necessary elements of the artwork (the object itself and its shadows) to create a clean, long-lasting, and useful image.

Digital Treasure Trove: Post-Production / Image Cropping

Contributed by PAFA Museum Collections

An important step of the digitization workflow is post-production. This step always performed after the actual digital asset is created, hence the prefix “post”. This crucial process allows us to make minor adjustments for things like light and color, as well as cropping the dimensions to match the work being viewed. Sometimes, this is as simple as matching the rectangular edge of a TIFF file to the edge of a rectangular painting. Other times, this is more complicated, with works that are not perfectly square, are three-dimensional, or have other non-standard edges. In any case, it is our job to produce and maintain these cleaned up images—what we would call “access files” for broad dissemination to our audiences. These files are unique and distinct from our archival “master files,” which do not get the ‘post-production’ treatment and are kept for posterity.

It has been a slow task, with the need to go through and edit images one by one, but we are nearly finished. In fact, the Museum is almost ready to integrate these legacy files with the newly photographed works of art taken this year.
