How to photograph and modify crystal carvings, ornaments, pendants, etc. on a black background

A piece of black flannel, a piece of white flannel, and a tripod.

Reflector Just find a large whiteboard, and the KT board for advertising is very good.

Shooting angle macro, because of the distance of the subject, the effect varies greatly, and here there is no question of how much distance is appropriate, but I want to explain that these different effects should be used for different purposes.

Photographing crystals is quite an interesting artistic creation. Because, crystals have different modeling effects for different lighting methods. Photographers can use light to outline the outline of the crystal as they like, and can skillfully use the reflection of the crystal to reveal its crystal clear nature; The photographer can use a white edge light to outline the shape of the crystal in front of a black background; It is also possible to use opposite means to achieve the same goal in front of a white background.

Now we will introduce how to shoot crystals in front of a black background. Common Lights for Shooting Crystals: Backlight, Bottom Light, Top Light The most common mistake of shooting crystals is to use a light to shine directly on the subject from the front.

With the lamp in this way, there will inevitably be a dazzling reflection on the crystal, like a mirror. The crystal sometimes reflects the image of the lamp as it is, making the picture very beautiful. So, no matter what reflective object you photograph, don't use direct light!

In other words, never shine light directly on the surface of the crystal from the front. So, what kind of lighting should be used to photograph crystals? There are probably no more than the following three:

1. a backlight; 2, the bottom light, 3, the item light. For example, how should we photograph a crystal? The first thing to do is to photograph the outline of the crystal in front of the white background, that is, to outline a few white highlights on the main edge of the crystal.

Place a lamp above the top of the crystal and add a diffuser in front of the lamp. If the area of the light source is too large, it affects the darkness of the background. You can use black paper to block the light source or add a baffle behind the lamp.

At this time, the bottom of the crystal will appear round after round of white highlights. Then, place a piece of white paper on each side of the crystal that is higher than the crystal, and a white highlight will appear on the perimeter of the crystal. With the outlined highlights, the shape of the crystal is revealed against a white background, but that's not enough.

To explain the texture of the crystal, it is also necessary to add a decorative highlight to the crystal. If you shoot close-ups, the digital camera is very close to the cup, be careful not to block the light with the camera.

It's not very troublesome, use a black tile and put it on the balcony to shoot, it's best, you don't need to deal with it much, otherwise you won't be able to shoot more water.

Open your ** with ps, select the magic eraser tool, and then click on the background, the background will disappear, and then save it in png format, which is the background transparent**

I can't understand your expression!

This is shot with the manual mode of a DSLR camera, with a black cloth as the background, from the upper left part of the object to the side light, when shooting, focus and ** according to the white object, and then in post-production, appropriately fill the light and depress the dark part (deliberately lose some dark details and layers), so that the high contrast comes out, and you can get a ** of the light and dark effect as shown in the figure.

This should not be the result of post-retouching, but the effect of using non-reflective black material as the base and turning on the flash to shoot. If it is the result of post-retouching, the surroundings will not be so dim, and the overall repair will be very bright. If you pay attention to the shadows, you should also use fill lights.

This effect is very important in the early shoot, just use dark gold velvet as the background.

In case there is a reflection, adjust the "color scale" in the later stage to make the black dark.

If you do it later, you can do it as a personal work, and if you are not careful, it is easy to feel fake.

The black flannel itself is not easy to reflect, and this has been post-processed to cut out the reflective part.

This picture is a lamination diagram! Image - Adjust - Selectable color, if you want to adjust white, color white, then adjust the values of C, M, Y, K, and that's it!

Select the impurities and fill them with black.

Noise under the filter Remove noise!

First use a magic wand or an eraser, and then use a pen tool, and you can't just use CDR to pick it.

1. The design software used in the demonstration is Photoshop, and the software version is Adobe Photoshop CS6.

2. According to the problem description, open a black background, and the theme color of the icon is also similar to the background.

3. Find the Lasso tool in the left toolbar and click Select.

4. Use the lasso tool to select the ** theme, and finally form a closed loop, and you can get the selection of the main body.

5. After removing the background color, use the eraser tool to adjust the edge of the subject, and you can see that we have got the main part on the black background.

You can use photoshop's channels and adjustment layers to cut out images on a black background.

1.Open Photoshop

2.Open it**.

2.The channel panel --- copy the red, blue, and green channels respectively as copy 3Go back to the Layers panel --- fill the background layer with black 4

Load the Red Copy channel selection --- create a new red adjustment layer (ff0000)5Load the "Green Copy" channel selection --- create a new green adjustment layer (00ff00)6Load the Blue Copy channel selection --- create a new blue adjustment layer (0000ff)7

Finally, change the layer mode of each of the three color adjustment layers to Filter Color

8.Remove the black background layer.

9.Completed.

Copy a layer first, then Ctrl+M curve, Ctrl+L color level, etc., adjust to as bright as possible until you see obvious edges, and then cut out a selection according to this figure, select the layer below that has not been adjusted, press Ctrl+J to cut it out, and then delete the excessive adjustment**.

PS CS5-4 intelligent quick selection tool is the best to use, the deduction of the picture is manual labor, and the plug-in effect is not good, like your picture.

1 Use the quick tool to select the mask under the 2-point layer (this step can be modified).

3。Zoom in with the Paint Stroke tool plus the black and white conversion below to modify the selection in the mask.

This method is the most convenient for me, and there are many convenient tools in the automatic selection to help us deduct the image effect.

Of course, there is also the oldest way to use the path (pen head) to deduct the map,(This is the most primitive way,Most PS users are using it,There is a reason for his survival)

PS plug-in and CS self-buckle diagram is just really good for hair.

I already answered when you asked. Get it done in a few minutes, and take care of the details yourself. The rough diagram is as follows:

You can hide the black with the color filter in Layer Mode, use a layer mask for unclean areas, and paint unclean areas with a brush when the foreground color is black.

I hope I can help you, please adopt, thank you!
