How to whiten teeth in Photoshop

The key to natural whitening of teeth in Photoshop is to select precisely, use adjustment layers and moderate control parameters. 1. Use the Quick Selection Tool or the Object Selection Tool to accurately select the tooth area. If necessary, shrink the selection 1 to 2 pixels to avoid affecting the lip color, and save the selection for later use; 2. Create a new curve adjustment layer to brighten the midtones, and finely adjust the blue and blue to remove the yellow feeling. When it is seriously yellow, you can use the hue/saturation adjustment layer to reduce the yellow saturation. At the same time, add a reverse mask to the adjustment layer and use a white soft edge brush to brush the effect locally; 3. Control the brightening and cool tone amplitude to maintain the light-blank realism of the teeth, and appropriately add Gaussian blur to optimize the transition. Multiple photos need to unify the whiteness.

how to calculate compound interest in excel

Calculation of compound interest can be achieved in Excel through FV functions or manual formulas. 1. Prepare the data structure, including principal, annual interest rate, compound interest frequency and time; 2. Use the FV function to enter the interest rate for each period (annual interest rate ÷ compound interest times), the total number of periods (years × compound interest times), the amount of payment per period is 0, the present value is the principal and add a negative sign; 3. Manually write the multiplication formula: principal × (1 interest rate)^ years, applicable to compound interest by year; 4. If compound interest by month, then divide the annual interest rate by 12, and multiply by 12, the formula becomes principal × (1 annual interest rate/12)^ (years × 12), thereby increasing the final return.

How to make an image look like a painting in Photoshop

The key to using Photoshop to convert photos into natural and textured painting style is to use filters reasonably, superimpose textures, and adjust colors and details. 1.

Overlay the canvas or paper texture layers, and enhance the texture of the picture through "Soft Light" or "Overall" blending mode; 3. Adjust the color and contrast through tools such as "Hue/Saturation", "Curve", and "Color Balance" to enhance the overall atmosphere; 4. Finally, use "Intelligent Sharpening", "Liquefaction" and brush tools to enhance the edges and brushstrokes, making the picture more hand-painted. Each step should be kept natural and avoid over-treatment.
