Time-Lapse Planning
Does it move?
Every image is a single frame
Final movie at 30 fps?
15 second intervals X 30 fps X Desired Clip Length
30 x 5 = 150 photos
15 x 30 x 5 = 2,250 seconds or 37.5 minutes
Capture
Camera Settings
RAW vs JPEG
Processing Time Considerations
Lightroom or Aperture for Batch Processing
RAW Sizes
Small RAW is usually still greater than 1920x1080 (HD)
Full RAW = Higher Quality when ―Downsampled‖ from 4k
resolution to1080p HD
Capture

Battery Grip
Sufficient Memory Card Space
Full RAW + 32 GB card = approx. 1,000 photos

Processing
Boosting Blacks, Contrast, Noise Reduction, etc.
Once your find a ―recipe‖ for a single photo, copy these
settings to every photo in the sequence.
Importance of shooting Manual for consistent fixes
Even if you are under- or over-exposed, as long as every
photo has the same problem, it’s an easy fix.
Don’t Batch Process Spot Removal
Moving objects, algorithm could change over multiple frames
Processing
Once editing is complete, export as JPEGs to a new folder
Keep each sequence in a separate folder
―Astro Angle 1‖ and ―Astro Angle 2‖
Motion
Editing Software
Adobe Premiere Pro, Adobe After Effects, Quicktime Pro
Personal preference is Premiere Pro
