Are you new to Photoshop? Have you been trying to teach yourself the basics of Photoshop but have found the amount of educational material available on the net a bit overwhelming?

This tutorial is part of a 25-part video series demonstrating everything you will need to know to start working in Photoshop.

Photoshop Basix, by Adobe Certified Expert and Instructor, Martin Perhiniak includes 25 short video tutorials, around 5 – 10 minutes in length that will teach you all the fundamentals of working with Photoshop.

    Nice. Love those tutorials, very useful as I’m a big noob. But in this one, I don’t really understand the clipping. What is that? I mean except two big bars on the sides of the histogram? I read stuff about, but I can’t get a simple explanation to understand…

    • http://www.inspiks.com loswl

      “Clipping” means that the color value of a pixel has either been pushed to pure black (0, 0, 0 RGB) or pure white (255, 255, 255). When a large area of pixels is clipped, it contains no detail. Hope that helps.

    Good tutorial, I like the fist part.

    I would prefer for the last picture to not “sacrifice” big parts of nuances.

    You get 26, 0, 225. I see more something like 0, 0.90, 237 (0.90 with ithe grey arrow, the middle tons for the contrast).

    I also use the Option (Alt) key on the arrows but I stop immediately when I see the saturated colors coming.
    I prefer to use the curves for the middle tons and get a better contrast with this tool, but it’s not the point of this tutorial.

    This tutorial is more appropriated for “normal” pictures, so careful with this technique on a snowy pictures.

    Such a misunderstood area, the Histogram. Great job of writing up a door-opener on this. Maybe less people will look at me funny in future when I tell them that their photograph is “bleeding”!

  • Luis F

    Great series Just what I wanted
    waiting the next tuts

  • http://www.wpgallery.com IrfanSt

    Nice video, thanks.

  • ng

    I always wonder if, there is any “filter” or “plug-in” that can help me sorting photos based on histogram info, instead of file name, date, modified date etc. , anyone knows? thanks a lot on this!

  • http://www.vegatopia.com Machteld

    Hello Martin, thank you for your tutorials.

    I was wondering when to use Levels and when to use Shadow/Highlights? Is this a personal preference or is it absolutely necessary to use the one or the other in a certain project?

    @Adam Fairhead: bleeding means clipping?

  • Cemil

    thanks… nice video…

  • sheshu

    What kind of accent is that? Scottish?

    • Gosh

      Hahaha! I do hope this comment was made in jest.

    • neil

      yes, it is a Scottish/Hungarian accent.

  • niko

    Wonderful video tutorial.

    I’ve been using Photoshop for years and it’s just refreshing to re-learn these basics. Thank you.

  • knuckles

    small question- What’s the difference between “cached” and “uncached” with the histogram? I don’t see much difference, but I’d like to understand the terminology at least.

    (And thanks much for these videos! It’s almost refreshing to find such clear & simple explanations of these basic concepts and tools.)

  • Jck

    I was wondering why I didn’t get a “heat image” while holding alt but it only works in RGB mode, doesn’t it (I was in CMYK)?
