Illustration of the steps of drawing a color still life glass, these test points should be kept in mind

In daily practice of color still life, glassware as a type of object has a high exit rate, and most of them are It appears in the form of wine bottles, wine glasses, glasses, fruit plates, vases, etc. It is crystal clear, colorless and cold, and has strong light transmittance. Because it reacts strongly to environmental colors, the highlights and reflections are very dazzling and can directly reflect the The color of the light source, so it will be more difficult to master.

When depicting, master the depiction of the transparent and opaque parts of the glass bottle. Pay attention to the color and texture of the liquid in the bottle. When depicting, the object should be placed in the picture to achieve integration with the surrounding environment. . We use glass as the representative of glassware to explain in depth the specific painting steps and color mixing formulas.

Step 1: Deal with the composition of the picture

Step 2: Apply the background color and draw the color of the liquid in the cup.

Step 3: Draw the color of the glass itself, paying attention to its transparent texture and its relationship with the surrounding color.

Step 4: Emphasize the relationship between reality and reality in the overall picture, and depict the details and texture of the rim and body of the cup.

In general, there are several key points in the depiction of glassware:

1. The glassware must be transparent, and using very bright edges is the best way to express it. , first lay out the color of the background and liquid parts, use heavy colors to outline its shape, and after drying, use different changes of dry strokes to quickly bring out the highlights and reflections

2. The glassware must be hard. The overall depiction should be very crisp and neat, and the brushstrokes should follow the shape. You must be decisive when painting the edge of the glassware, so as to better highlight the hard and light texture and charm of the glassware

The difficulty with glassware lies in the relationship between the brightness and hue between the color of the liquid itself and the color of the glassware itself. The transparency part is darker than the natural color due to light exposure. When drawing the edge line, pay attention to the volume factor of the vessel itself. The liquid part must reflect the volume of the vessel. The reflective part must pay attention to the performance of the ambient color, plus highlights. The processing can fully express the rich texture of glassware and liquid. How to use PS to make a glass overlap?

As long as each layer is below the previous layer, it will be an overlapping effect.

Put the first glass layer on top. The second layer is next, and the third layer is below the second layer, that's it. Teach you how to use PS to cut out a transparent glass

Cutting out is also a method often used in PS. Among them, cutting out transparent objects should be considered more difficult. Here is an introduction to how to cut out a transparent glass using PS. The glass method is very simple, let’s learn it together!

Steps:

1. File-Open. Select a glass material picture.

2. Switch to the channel panel, click to observe the three channels of red, green, and blue, and select the channel with the strongest black and white contrast. The blue channel with the strongest black and white contrast in this picture is the blue channel and make a copy. .

3. Copy the blue channel, Ctrl+L, adjust the color value of the blue channel as shown in the parameters.
