The journey ends with a few words of wisdom, a firm handshake and a friendly shove in the right direction. After 25 videos and five hours of video training - the world of levels is yours for the taking!

A colour cast is when the colour of an image shifts towards a specific hue, say green, to give the whole image an unsightly green tint. The reasons behind this and the resulting cast can be as numerous as the tools available to fix it. For this reason we'll take a classic example and put things right both manually and automatically.

So we know the difference between colour and luminance information, now's the time to look at dividing the two and working on each individually. Whether we're doing that with blend modes or the highly theoretical Lab colour space we're going to be opening our eyes to a whole new universe.

Made popular by the Camera Raw plug-in that ships along with Photoshop, the color histogram contains all 3 RGB channel histograms inside one window, giving a visually pleasing reference to colour information, how the channels interact and where exactly they don't.

Because the human eye doesn't see red, green and blue light equally we need a reliable way of representing the brightness of a pixel independent of colour. And so steps up the luminance histogram - the most accurate way of spotting clipped shadows and blown highlights threatening the very existence of your image!

Photoshop produces red, green and blue histograms inside an RGB image, when it's done it puts the results into a composite version and displays it as the standard view. How that composite view is calculated decides how we see clipping inside our images - and as you'll bear witness, things aren't always what they seem!

It's time to summarize the RGB, luminance and Colour histograms available inside Photoshop, and talk more specifically and indeed more technically about the statistics available in the expanded view. It's not necessarily about how to ask questions, it more about deciphering the often misunderstood answers that the histogram palette is shouting out!

With one foot inside the CMYK colour space but the other firmly rooted to RGB land we begin to harness the power of number-based skin tone adjustments using the colour sampler tool and the levels command. Altogether a more involved but highly rewarding way to work that's employed by studios and portrait professionals around the world.

Modifying skin tones can be a tricky task, thankfully within levels we have a number of fully-adjustable yet simple techniques that wield some great results. Some of these results depend on the user’s perception of what's right, or what's wrong, with the colour of the skin, other results are aided by a library of skin tone swatches that are prepared to work overtime to get you the results you demand.

So we know what shadows and highlights are, and we also know a way of locating and using them in conjunction with the relevant eyedroppers - but surely there must be a more accurate way of finding the brightest and darkest pixels inside an image? Well I'm glad you asked, as with assistance from the threshold command, the colour sampler tool, the info palette and the eyedroppers we can achieve pinpoint accuracy in a modest amount of time.
