The reason I actually had you dramatize the picture was to draw your eye to the different light and dark sections of the photograph that became very obvious when you did so. You can use these ‘bands’ as a guideline for where to put your edits, and at which angle they should go. Did you actually try the homework? Well, this is another dirty trick you can keep in your tool belt. | The reason I actually had you dramatize the picture was to draw your eye to the different light and dark sections of the photograph that became very obvious when you did so.

Like Darktable, Rawtherapee also supports L*a*b adjustments. Click on the first tab or press Alt+E and scroll down to L*a*b Adjustments. Now, don’t confuse them with the lightness, contrast & saturation in exposure. This is not the same thing. | Like Darktable, Rawtherapee also supports L*a*b adjustments.

+ | Dans les ajustements L*a*b, vous verrez que chaque canal a sa propre courbe, mais ils commencent tous en étant linéaires. Vous pouvez utiliser les flèches déroulantes de chacun des trois pour les modifier. Juste en dessous, vous verrez six autres onglets qui peuvent être ajustés. « LT », « CT » et « TT » ont chacun une ligne horizontale ; pour les activer, tirez celles-ci vers le bas pour ouvrir l' | ||

+ | **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. | ||

+ | **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, | ||

+ | |||
+ | 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 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. | ||
- | 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. | + | Please send all comments and corrections to: misc@fullcirclemagazine.org** |

Assurez-vous que les paramètres de luminosité et de contraste soient à des niveaux qui rendent les choses naturelles. Une forte luminosité et un constraste faible m'ont obligé à travailler encore et encore sur l' | ||
