Timelapse Photography – Post Production

After returning back, I was responsible for processing the images while Suzanne was responsible for compositing them in Premiere. Shooting in RAW format with the camera produced both JPEG and CR2 versions of each image;


I opened the CR2 files in the Photoshop RAW editor, then adjusted various settings on the first photo to improve on the current parameters, with minimal quality loss due to the type of format used which essentially retains raw data for the image, such as exposure and colour temperature.


I saved the setting as an .XMP file which was a significant improvement to workflow efficiency – as I could then apply the same settings used for the first image, to all other RAW images in the sequence. I batch exported the images as JPEG files for use in Premiere, and uploaded these to our shared OneDrive (Onedrive.com, 2014) folder in order for Suzanne to access them easily. She began to arrange the first batch of images – the tide – in Premiere while I switched to my Linux machine and accessed the sunset images from OneDrive. Using the terminal I installed the ImageMagick (ImageMagick LLC, 2014) package and used the “mogrify -scale” command to resize the images, then after using “identify *.jpg” to confirm the operation, the “mogrify -gravity North -crop” command to crop all the photos, anchored at the top (or North) of the images.


The benefit of using the terminal for this task was solely the speed of the operation; using a wildcard (*.jpg) I was able to crop all the .jpg images present in the folder at once, as well as overwrite the originals simultaneously. Having done this I went back into Windows 8 to use Photoshop, applying an Unsharp Mask filter to all the images to improve contrast. I finished by replacing the unprocessed images on OneDrive with the new cropped and processed ones ready for compositing in Premiere.
