what are some technique you learn for sharpen photo?
When is comes to sharpen photo pixel from the lighting up area to make more appealing, by darken some area up of the image that make it more contrast. The ways to sharpen photo or images like independent, darken, lighten, contrast, comparative, and HSL modes. When it comes to independent it deals with normal and dissolving effects. By darken up the white areas so it depending on blending and the difference in value through applied and underlying.
Then theres lighten which the opposite is for the black areas but leaves the underlying pixels won’t change. Contrast can change the percent of gray pixels which leaves a defferent effect, and comparative is black by looking at each channel along with subtracting the underlying color form the overlying color or opposite which gives a higher result in brightness.
Finally, the core of sharpen ones photo or image which is HSL mode and it effects by the hue, saturation, color, and luminosity. Hues can create different results in color by brightness and saturation. And what does saturation do is similar to hue, but it creates different results in color by brightness and hue. The luminosity and color plays a key role by the results from color with the hue and saturation of the underlying color and the luminosity of the overlying color.
