  • A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. An example of an analogue electronic band-pass filter is an RLC circuit (a resistor–inductor–capacitor circuit).

  • A notably happy or successful moment

  • A high-frequency sound or musical note

  • a lofty level or position or degree; "summer temperatures reached an all-time high"

  • A high point, level, or figure

  • greater than normal in degree or intensity or amount; "a high temperature"; "a high price"; "the high point of his career"; "high risks"; "has high hopes"; "the river is high"; "he has a high opinion of himself"

  • at a great altitude; "he climbed high on the ladder"

  • A particularly bad or difficult moment

  • A state of depression or low spirits

  • less than normal in degree or intensity or amount; "low prices"; "the reservoir is low"

  • an air mass of lower pressure; often brings precipitation; "a low moved in over night bringing sleet and snow"

Hello, I really need to get out of the house....my back hurts and the sunsets are duds these days so I stayed in tonight. I was in the mood to process something so here I am. HDR really pulls out the wrinkles....anyway, that's me and some glamour glow which I now do in Photoshop....Much better than NIK...I have greater local processing ability.

Glamour Glow in Photoshop
Copy Layer
Add Gaussian blur to desired level of blur and remember that number and hit cancel.
Apply High pass filter at the same number as the blur
Apply Gaussian blur over the high pass filter at 1/3 the first number
Change mode to overlay
Create mask and fill with white
Grab a black brush of your choice and adjust the opacity. Then mask out the unwanted areas of "Glow."

The picture consists out of two exposures. One as a main, one for the Apple logo. I add a High pass filter for some extra details, got rid of some color and that's about it.
