Did a photographer look at my photo and want to know what lighting effect it was and what kind of camera it was taken with?

Or use a 5000K light source! Still PS adjustment! Or your camera automatically balances! Is the lamp you use incandescent?

This is the answer I found for you:

This is the reason of CMOS chip, because the CMOS chip of card camera is very small, and the processor can't fully analyze it when analyzing the color, so the photos taken will feel yellow. This is also a common problem of card cameras, but some are slightly better and some are not. However, this can be fixed by using PS software or the software that comes with the camera. There are tutorials online, and the landlord can find them online by himself. As long as the finished photos are slightly repaired, they are good photos. Now photography is 80% photography plus 40% post-photography, not just photography.

Repair photo color

1. First, use PS software to import the required photos, and right-click to copy Beijing (CTRL+J) to get the background copy layer.

2. Open the channel panel and check the channels. It is found that the blue channel is dark and other channels are basically normal.

3, click on the "create a new fill adjustment layer" button at the bottom of the layer panel, and select the common channel mixer to adjust the layer.

4. Because the original image is red, we switch the green channel in the channel mixer dialog box and pull the red slider to the right, just like inputting a little green in the red channel, in order to reduce the red, we increase the green in turn.

5. We switch to the blue channel and use the data of the green channel to repair the blue channel. We add 100% green. As you can see, the characters in the picture appear white and the basic color of the picture is restored.

6. The color is not very satisfactory now. Let's fine-tune it again. Before adjusting the color, use the color sampler to take an epilepsy in the middle of the skin. As you can see, the red color of this sample is 2 1 1, the green color is 147, and the blue color is 94, indicating that the green lotus blue is still on the low side.

7. Add a color balance adjustment layer. We are hesitant to adjust our skin color by comparing the information panel. The highlight area is already dim, so we focus on adjusting the shadow area and the middle tone area, remove the "keep height" hook, and adjust the yin and yang area first.

8. Adjust the shadow area as shown in the figure, focusing on green and blue, and pay attention to the change of data on the information panel.

9. In the midtone area, according to the ratio that red is 40%-50% more than green and green is 20%-30% more than blue, the adjusted skin color becomes better.

10. Add a curve adjustment layer to make the whole image brighter and the skin whiter.

1 1. Press CTRL+Shift+Alt+E to stamp the layer and add a white layer on the layer 1. Set the color of the layer mode to slightly reduce the opacity, draw two strokes on the lips and face with a red brush, and add blush and lipstick.

12. The second layer is applied with Gaussian blur, and the red color gradually spreads, and Segashan's blush and lipstick are natural.

13, execute the shortcut key CTRL+Shift+Alt+E to merge all visible layers, so that we have finished this yellowish photo.

Introduction to CMOS

CMOS, known as complementary metal oxide semiconductor in Chinese, is an important chip in computer system, which holds the most basic data of system startup. The manufacturing technology of CMOS is no different from that of general computer chips, mainly using semiconductors made of silicon and germanium, so that semiconductors with N (charged) and P (charged) energy levels are stored on CMOS, and the currents generated by these two complementary effects can be recorded and interpreted as images by processing chips. Later, it was found that CMOS can also be used as an image sensor in digital photography after processing, and CMOS sensors can be subdivided into passive pixel sensors and active pixel sensors.

Landlord, since your camera is yellow, you can use the above tutorial to repair the yellow photo. I found this tutorial on the internet, which is specially designed to repair yellow photos. The landlord might as well try to repair your photo!
