Photographic white paper

It is very simple to achieve a completely white background indoors, which is generally called seamless white abroad.

Need to prepare materials

1, light source, it is recommended to flash, there are many lamps, and there are corresponding lamp holders.

2. Camera

3. Exposure meter (optional)

4. Color card or gray card (optional)

5. White background (white wall or background paper)

In order to make the photos whiter, we should not only calibrate the white balance, but also increase the exposure to make the photos whiter.

step

1, give priority to the subject.

2. Hang background paper on the back of the main body, and use two lamps to illuminate the background directly behind the main body at an angle of about 45 degrees. The distance between the two lamps and the background should be equal, and the output power should be the same.

3. Adjust the power of the two background lights through the exposure meter to make the background brighter than the main body. If there is no exposure meter, please bring up the histogram of the camera.

4. Calibrate the white balance and color through the gray card or color card.

5. Start shooting

The principle of adding white and reducing black is used here, where white is needed, the exposure is increased, and where black is needed, the exposure is reduced.

In addition, give the subject a hint: because there are more background light, it will be reflected on the lens and directly irradiated on the lens, and then the anti-glare ability of the lens will be tested. If the background is too bright, it is easy to reduce the contrast of the photo and make it dark. The solution is to use a hood and baffle to block the light that does not need to shine on the lens.
