Photolithography

Have you ever thought of combining photo painting with portraits to add cool photo effects to your portraits?

1. Preparation and setting before shooting

You need to make these preparations:

Hand held light source. You need a portable light source that can be held in your hand to "draw" patterns in the air. Flashlight, mobile phone and fluorescent stick can all be used.

tripod. Photo painting requires long-time exposure. Even some special photo painting forms of "rotating the camera without moving the main body" need to use a tripod to control the rotation law of the camera.

flash lamp. It is best to use an off-board flash with adjustable angle, output power and color temperature to illuminate and "solidify" the main body.

A dark scene. Because other forms of light sources appear directly in the background, they may have an impact on the photo painting. Therefore, you can choose a room without windows or with dark thick curtains for creation, and outdoor scenes far away from the ambient light source at night can also be used.

In terms of setting, you should pay attention to the following points:

It is recommended to use the shutter priority mode, adjust the sensitivity to the lowest, and lower the exposure compensation according to the actual situation.

The shutter speed setting depends on the completion time of your action. You can do "pre Photo Painting" first, try to draw a pattern in the air, record the approximate time, and then set the shutter speed on this basis.

It is best to manually adjust the output power of the flash lamp. You can first determine the flash position and conduct several trial shots to adjust the most appropriate output power.

2. Start your shooting

In light painting, people and cameras are relatively moving, so how to take a clear portrait? You can choose two exposures and combine them, or use a flash to "freeze" the subject.

Set the flash synchronization mode to "front curtain synchronization", so that the flash will illuminate the main body at the beginning of exposure; Then, the long-time exposure is used to "capture" the trajectory of the light painting.

It is better to conduct "pre focusing" before shooting: use manual focusing mode to adjust the focus ring to the appropriate position, or use the light source to illuminate the subject's face first, and lock the focus after completing single point focusing. This way, you can at least keep the subject's face clear.

3. Use multiple light sources

You can create more diversified lighting effects by using different types and numbers of light sources.

You can use intermittent and flashing light sources (such as laser pens) to draw dashed lines:

You can also use composite multi-color light sources to draw colorful and changing lines:

If economic conditions permit, you can also use some more high-end "professional level light painting equipment", such as pixel stick, to produce more professional level light painting effects.

The so-called pixel stick is actually a "stick" formed by many small LED lights. You can independently control the turning on and off of each small light, and some can even adjust the color.

The effect is like this:

4. Try different shooting techniques

In addition to "shaking the light in front of the lens", you can also try some other shooting techniques.

You can use other tools to "help" you draw light tracks. For example, you can hang a small lantern on a ceiling fan and turn it:

You can also consider using the "explosive zoom" method: prepare a zoom lens with a large zoom range, adjust the zoom ring as quickly as possible, turn the light source in the background into a radial light track, and then use the flash to "solidify" the main body.

However, you may need to change the flash synchronization mode to "rear curtain synchronization" during shooting.
