Lightroom and Photoshop guru Erin Quigley runs excellent training sessions specifically aimed at underwater photographers. In conjunction with this, she has published a series of free tutorials and these are all now available via a single landing page on her website. There is a mixture of lessons for Lightroom and Photoshop and there are techniques suitable for both beginner and advanced users.
Going forward, Erin plans to add a new tutorial each month. Some of the existing ones are videos and some are just text and graphics, but all of them are techniques that Erin hopes: “Everyone could benefit from knowing.”
