One brother tinkered on the Macintosh while the other dabbled in photography.

Together, through a shared love for image processing, the Knoll brothers created the world's most renowned image and photo editing software: Display. Born out of inspiration and developed by necessity, this program would go on to be nurtured by Adobe and rechristened as Adobe Photoshop.

That baby is now 25 years old. Almost every field in the world – from forensic science to photography – has been radically impacted by its existence.

Next to the camera, a licensed copy of Photoshop is an essential tool for photographers. Retouching photos is de rigueur for the visual arts. No, the beginner photographer's education does not stop at the camera. It continues with every photo opened in Photoshop. The learning waves are overwhelming, but online video tutorials on Photoshop make it easier to surf.

Here are eight free lectures to get you started with the graphic editor we all love.

Photoshop Tutorials from B and H

B&H Photos has long been the go-to source for the latest photographic equipment and optic accessories. The international photography superstore has an educational channel where professionals dish out the latest advice on anything and everything related to the camera.

The YouTube channel may seem like a tiny thread hanging from their massive fabric of resources, but check out a playlist like their Event Space series of 250+ videos and you'll realize its tremendous value for beginner photographers.

Use the channel search (next to the "About" link) to speed search for all Photoshop videos. Some of the best professional names like Jeff Cable, Andy Graber, and Julieanne Kost, among others, are behind some of these awesome Photoshop lectures.

The series of instructionals are mixed and matched with other photography tips and with Lightroom, but if you want to go from beginner to a professional photographer, you really should watch them all.

And if you have ever wondered what "B&H" stands for – the business got its name from Blimie Schreiber and her husband, Herbert.

Udemy – Photoshop for Photographers

Photoshop for Photographers

Your first introduction to Udemy could (and should) have been Karl Taylor's open and free photography course. Regardless, this academic platform is a potpourri of free and paid courses spanning many different topics.

You can teach yourself Photoshop with the 153-hour tutorial by Manfred Werner or with some of the crash courses that focus on a specific version of Photoshop, like the condensed five-hour one by Jeremy Shuback.

The Photoshop for Photographers course could be your second pick. In it, you'll get 31 lectures over six hours that run through the techniques a photographer needs in Photoshop. Learn to use Camera Raw, replace skies, digital blending, shoot into the sun, manipulate with HDR, layers, masks, and blending modes. Learn methods for black-and-white shots, panoramas, other special effects, and printing.

If you are using Photoshop CS4, CS5, CS6 & CC – hop in. The well-structured course costs $67 and is suitable for all levels of learners. You also get 40 RAW files to practice along with Serge Ramelli. You can also catch him with his 300+ videos on his own YouTube channel.
