The gem’s color is generally stable to light, but prolonged exposure to heat or sunlight might cause fading in yellow-to-brown, reddish brown, or dark brown topaz. High heat or sudden temperature changes can cause breaks in topaz. Its toughness rating is poor due to its cleavage Topaz rates 8 on the Mohs hardness scale. Or they use topaz in pieces that aren’t exposed to too much wear, like pendants and pins. Jewelers prefer to set valuable topaz gems in protective mountings. To reduce the risk of breakage, cutters orient faceted topaz so the cleavage direction is at about a 15-degree angle to the table. It’s not very tough, so a hard blow might split it, and extreme pressure or sharp temperature changes might cause it to break. For example, diamond is only one number away, but it’s many times harder than gems in the corundum family.īecause of its basal cleavage, topaz requires special care during cutting, polishing, and mounting. The steps between the minerals are not evenly spaced. The numbers are based on the relative ease or difficulty with which one mineral can be scratched by another. Gem and mineral hardness is measured on the Mohs scale.

TOPAZ CLEAN NOT SHOWING UP SKIN
Topaz Clean is a powerful detail smoothing and edge stylization plug-in that simplifies advanced techniques typically used for creating smooth, flawless skin and curly, vectorized effects – allowing you to quickly and easily reduce or remove the depth of detail within images, while maintaining important structural detail and enhancing edges. This is also sort of a 2fer because I used the image that had previously be rendered with the curly filter to show how applying more than one filter can give you an infinite number of variations. It is a bit over the top, but I wanted to emphasize the effect so you could easily see what the filter was capable of doing. Here is a bear image straight out of the camera that I’ll use to show some more filters in action. Katie before (left) and after the smooth filter. I’m not trying to make a mannequin, so I always leave a few smile lines and such to give the image a much more realistic look. For example, I love what the skin softener does to well skin, but not so much to hair or eyes. I prefer to use this filter in an editor or the new photoFXlab that will let you work on layers so that you can mask in or out the effects. Katie’s eyes with the curly smooth filter. Katie’s eyes without the curly smooth filter. It is one of the plugins that I put in the “you need to own this one” category! I love what it does for fur and I love what it does for eyes! Wicked cool eyes! I use it on everything from birds and wildlife to glamour re-touching. I really like the Clean 3 plugin from Topaz Labs a lot and use it on a lot of different images.
