Digital contact sheets, Mac

A recent visit to see Sid Shelton’s Rock Against Racism (see here) with his original contact sheets in a display cabinet, again left me looking for a way to achieve something similarly organic (with the coloured scribbles indicating selects) with digital files.

After some research and experiment, I came up with the following approach that makes use of Lightroom and Preview on the Mac.

    1. Screen Shot 2016-08-06 at 06.50.37Create a contact sheet layout in LR’s print module (there are many online resources showing how to do this if needed) and export it as a pdf. It is the second step that is a little hidden – the dialogue box shows how this functionality is in the ‘printer’ menu at the bottom-right of the screen.
    2. The pdf can now be opened with Preview on the Mac. Preview also acts as the Mac’s built-in file editor and has a few tricks including annotation of pdfs, exporting files as different types, and resizing files. To put highlight markers around selects, use tools/annotate/line – this then brings up options for line thickness and colour. Save the file when done.
    3. At this stage, the file size is likely to be large and not suitable for sharing online, but useful for printing if that is something wanted. To reduce the Screen Shot 2016-08-06 at 07.07.15file size, make a duplicate (if the full size file is to be retained) and use Preview’s export function to export the file. Select export, then choose pdf, and select ‘quartize’ and reduce file size. In the case of my file it reduced its size from 10MB to 500KB. Perhaps re-applying the routine would reduce the file size further, but also result in a deterioration of image quality.
    4. Finally, upload the pdf to a blog as a media file and link into the post, setting it to open in a new window. This then brings up a readable copy of the contacts in a separate screen to the main blog post.
