**You can adjust these individual colors by grabbing a point and dragging it up or down. Unlike a music equalizer, you can also define curves in between. You can even ‘create’ colors in between other colors and manipulate those. What makes it really powerful is the little color-picker tool. You can select an area in your picture you want to manipulate, by color! Should anything go wrong, there is a reset in the top right in the first row of tabs, named curves. The last row ‘CC’, ‘LC’ and ‘CL’, are curves again. These basically allow you to move your histogram and manipulate color intensity. | **You can adjust these individual colors by grabbing a point and dragging it up or down.

**Go to ‘LH’ and turn on the equalizer. BEFORE you adjust anything, make sure your mouse is on a flat surface and you are holding it comfortably. The reason I say this, is that adjusting a color up or down, you will get lateral movement. Typically you try to avoid this unless it is intentional. You can also employ a ruler or box or other straight object, to rest the mouse against. Go easy on the adjustments, | **Go to ‘LH’ and turn on the equalizer.

**We are lucky that our boat has a rainbow on the hull, keep your eye on this when you adjust the color space. As our picture is mostly blue, keep zooming in to 1:1 on the sky and look at what is happening there. | **We are lucky that our boat has a rainbow on the hull, keep your eye on this when you adjust the color space.

Now that you have played with the brightness (luminosity according to hue) , now move to color, or chromaticity according to hue. Now, in this one, the saturation works in the upward direction. As I mentioned before, now you have the opportunity to adjust Cyan to adjust your blues. I want you to try to adjust Blue upwards. You will see how ‘kitch’ the picture becomes. However, if you drag Cyan, it enhances the overall blues in your picture. Remember to turn off the tool every few minutes, so you can visually track your changes. I say this, as sometimes it seems like you are not making a change, but turning the tool off reverts to the original image and your brain immediately catalogues the changes!** | Now that you have played with the brightness (luminosity according to hue) , now move to color, or chromaticity according to hue.

**Okay, now we move to HH. The adjustment in HH actually works sideways when you drag up and down. Dragging a point down moves the hue to the left, and dragging upwards moves the hue to the right. | **Okay, now we move to HH. The adjustment in HH actually works sideways when you drag up and down.

- | And that is the secret of the confusing L*a*b adjustments. LH up is down, CH works like you would expect, and HH up is left and down is right. Now this is speaking in terms of color and explaining by crayon. If you need to understand, re-read each section, for what it actually does. Also, practice to understand why each slider does what it does.** | + | And that is the secret of the confusing L*a*b adjustments.

**Tips: Remember to sit up straight and look at your monitor head on. A tilted monitor or skewed viewing angle can make a difference. Make sure your brightness and contrast settings are at levels that make things look natural. High brightness and low contrast have caught me out time-and-again working on someone else’s display. Less is more, work in small increments, unless over-the-top is what you were aiming for. | **Tips: Remember to sit up straight and look at your monitor head on.

Assurez-vous que les paramètres de luminosité et de contraste soient à des niveaux qui rendent les choses naturelles.
