Advanced Histograms Video Tutorial

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!

Improving Skin Tones with CMYK Values Video Tutorial

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.

Improving Skin Tones with RGB Values Video Tutorial

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.

Setting Black, White and Grey Points in Levels Video Tutorial

The eyedropper tools inside levels have the ability of setting specific values for specific pixels which is ideal when adjusting shadows, midtones and highlights. In the honour of levels we'll look at the eyedroppers and the theory of posterization followed by a full blown creative party as we play with those aforementioned eyedroppers, avoid the party-pooper that lives by the name of colour banding, and perform a very special party trick by transforming the grey eyedropper into a colour replacement tool. Doesn't time fly when you're having fun!!

Neutral Colours and Adding Saturation in Levels Video Tutorial

The term 'neutral colours' will feature a lot in the latter stages of this video series, so it's important to form an understanding of what it means - and how it can help us keep our colours accurate and true. On the other hand, adding saturation is the act of taking the colours, or more accurately the hues of an image, and making them more vivid by raising the intensity level - which is yet another level to understand!

The Auto and Options Buttons in Levels Video Tutorial

The levels dialogue box allows us to take control of the three automatic operations in auto levels, auto colour and auto contrast. Instead of just pushing a button and hoping for the best results, we can adjust black, grey and white points as well as control the percentage of pixels we want to ignore before finding the true base luminance for the given value. If that sounds confusing then this video's for you.

Levels in 16 Bit Mode Video Tutorial

The 16 bit mode allows us to introduce 32,000 luminance levels of data per channel, which in theory gives us access to billions of colour variations inside one RGB image, enough to make any number of extreme edits and not produce a single sign of colour banding or posterization. Sometimes seeing is understanding, and understanding is believing.

Levels Adjustment Layer Video Tutorial

In the world of non-destructive image editing with the levels command - the adjustment layer is king. Sitting at the top of the layers palette it gracefully and parametrically controls every pixel below it, and when used in combination with its equally powerful ally the luminance mask it becomes a true Photoshop force to be reckoned with.

Levels - Non Destructive Editing Video Tutorial

The more we know about a subject, the further we want to push ourselves to create the unimaginable. Before long we're building complex compositions from a single flat image, and the more complex we get, the more scope we need for readjusting settings that looked perfect five edits ago but no longer stand the test of time. The world of non-destructive editing inside levels brings about a whole new concept to an already able set of editing techniques.
