Join Richard Harrington for an in-depth discussion in this video Removing compression artifacts, part of Editing GoPro HERO Photos and Videos with Lightroom and Photoshop.
- Often times as you work with an image,…particularly a JPEG file,…it's easy to see compression artifacts.…This will be most visible in areas…with the sky or intense contrast.…Let's open up a JPEG file…and give it a little bit of attention inside Photoshop.…To start, I'll open up this image here,…and it's got a good high-contrast area.…But as we zoom in,…you'll start to notice some areas that are a little flat.…Some of the detail in the rocks here fall apart,…and you'll notice some oversimplification back here.…
Now, I'm at 300% magnification,…so it's easier to see the problems,…but there are definitely some noise issues.…One of my favorite tricks…is to duplicate that layer,…place it in Multiply mode,…a trick I showed you earlier,…and then simply merge those layers together.…Now, I'll apply a Base Exposure adjustment…to get this where I want it to be.…This initial exposure is just so…you get the image properly balanced…from a brightness point of view,…and it will help you spot potential problems.…
You may also want to boost the color a little bit.…
Author Rich Harrington starts with the basics: importing and organizing photos, correcting distortion, adjusting color and exposure, and getting ready for print. He then moves on to working with video: developing color and exposure with adjustment layers and presets, and then rendering out the adjustments for editing in another application. He wraps things up with a short, fun tutorial on assembling a time-lapse sequence. Start watching and learn the skills you need to get the best-looking footage from the GoPro and other action cameras.
