Add new tag, Lightroom, Photoshop, saturation, Vibrance

If you have upgraded to Photoshop CS3 or CS4 or if use Lightroom, then you have encountered Vibrance. Consider it a smarter less heavy handed form of Saturation. Saturation will saturate all colors equally, and it is easy to go over the edge into blobs of frightening color and loss of detail in a color that was pretty saturated to start with, just to get the saturation up on another color that started out less saturated. Vibrance on the other hand will saturate less-saturated colors more than ones that are already more saturated. It will also protect somewhat against oversaturating skin tones. Consider this example. The first image is before adjustments. My goal is to increase the saturation of the colors in the hat.

- Before
When I increase saturation, as shown in the second image, it not only increases the saturation of colors in the hat, but the skin gets yellow as well. In addition, the reds in the hat have started to go over the edge where you lose the detail of the yarn, because the reds were more saturated than the blues to start with.

- Increase Saturation by 50 (on scale of 0 to 100)
When I instead increase vibrance, notice that the skin color is pretty well preserved, and that I am able to get more saturated blues without losing the detail in the reds.

- Increase Vibrance by 80 (on scale of 0 to 100)
How well you see these changes will depend on your monitor. Give it a try with your own images, comparing what you get with saturation and with vibrance. I find I rarely use Saturation any more.
Photoshop CS3 has Vibrance in Camera Raw. CS4 also introduces a Vibrance adjustment layer.
Camera Raw, Clarity, Creative Effects, Lightroom

I showed you in my first clarity post how to use negative clarity in Lightroom or Camera Raw to soften skin. For a creative look, try heavy negative clarity on the whole image:

Before

Minus 100 Clarity (click on the Image to see larger)
Negative clarity reduces midtone edge contrast, so it softens or blurs. The pier is much less ffected by the softening because it has alot of deep shadow tones.

Before

After: Minus 100 Clarity
It looks kind of like a slide sandwich, or having a gaussian blur layer or smart filter in the soft light blending mode over the background layer (for those that have taken my filters, blending modes and montages creative class.) You may have to increase vibrance or saturation and contrast afterwards.
Note that Camera Raw introduced negative Clarity with CS4. It has been in Lightroom since version 1.
Photoshop, scrubby slider, tip
In Uncategorized on October 29, 2008 at 5:14 pm
Scrubby sliders are one of Photoshop’s great time saving features that you may not discover on your own. In many places in Photoshop, when you click and drag left or right on the name of a numeric setting, it adjusts the setting down or up — with no need to go into drop down boxes or to type in numbers. As an example, you may have worked with layer opacity, a setting in the layers palette that allows you to reduce the strength or opacity of a layer. The slow way to adjust the opacity is to click on the right facing drop down arrow to the right of 100%, and then adjust the slider that appears:

Drop down opacity slider - the slow way
Th quick way is to click on the word Opacity and drag the slider to the left to reduce it. Notice that as soon as you hover the mouse over the word, a hand with a double arrow appears … this is your indication that a scrubby slider is present:

Another scrubby slider is found up in the options bar for the text tool. You can type in the font size, or instead, click on the Tt symbol to the left of the size and drag!

Set text size with the scrubby slider.
You will find many scrubby sliders in numeric options for your tools. Look for them everywhere!
Canon, Digital Photography, G10

This is a digital photography post, rather than Photoshop or Lightroom, but it has me fascinated enough that I must send you over to Luminous-Landscape to see for yourself. Michael Reichman was shooting with the new $500 Canon G10 point and shoot along with his $40,000 Hasselblad/Phase 1 digital medium format system and found that image quality is pretty much comparable, on screen and for small and moderate size prints (up to 13″x19:).
Please, read for yourself:

This is a great site to monitor — excellent articles, reviews and training material.
Adjustment Brush, Lightroom, shortcut, tip
In Uncategorized on October 28, 2008 at 9:58 pm
If you are using the adjustment brush to make local image enhancements, you can hover over the pin to see the mask that you have drawn, but it shows for just a moment. To keep it on as you brush, type the letter O, for Overlay. To turn the overlay off, type O again.
If instead you use the adjustment brush in Camera Raw, simply check the Show Mask check box to see the mask. (Why isn’t this check box in Lightroom?)
Adjustment Brush, Camera Raw, Clarity, Lightroom, Photoshop

The clarity slider was introduced in Lightroom 1.1, and is also now in Camera Raw. A positive clarity value punches up an image, makes it look a little more three dimensional, by enhancing contrast along edges. The changes are concentrated in the midtones, and do little to highlights and shadows. Here is an example, a portion of an image with Clarity set to 0, and then set to 60.

Before Clarity Adjustment

Clarity of +60
60 may be a bit strong, but hopefully you see the difference. I find that almost all my images can use some clarity, at least 30. Note that it is not a substitute for sharpening, which does increase edge contrast, but along a much finer/narrower edge.
Now for the cool part: negative clarity, which as expected, decreases edge contrast. What are wrinkles, but edges?! So let’s soften some wrinkles and skin to get a little bit more of a healthy glow … my own face makes a great candidate. The first image shows no adjustment. In the second image, with the adjustment brush in LR (or CS4 Camera Raw) active, I set the Clarity slider to -100, and painted over my face, excluding the eyes and mouth.

Before Negative Clarity Adjustment

After Clarity Adjustment of -100
Actually, since some of my wrinkles are deep enough to be dark shadows, clarity only improves them a little, but it does much to soften the blotchiness of my skin. If -100 was too much, I can dial it back after painting (can I ever look too young??) And it is so easy to do.
