Hey, Hello everyone, I am Lao Mu.
In last week's article
"I want to give you this mobile phone photo editing software that is better than Lr." In
, I mentioned LUT, one of the new features of the bold photo editing 5.0, and today I will take you to play with this new function.
Of course, there are still benefits at the end of the article.
We all know that the RGB standard is one of the most commonly used standards in the field of photography and display. In the RGB standard, all colors are actually superimposed by the three colors of R (red), G (green), B (blue), and photos are also from this. "3D" in
3D LUT refers to this, and the full name of "LUT" is "Lookup Table". Therefore, the 3D LUT is translated as color lookup table .
Speaker
Assume that in a certain color lookup table, it is defined as follows:
When R=0, output R=10;
When G=0, output G=21;
When B=0, output B=9;
Then when R=1, continue, until each RGB value can output another new RGB value, which forms a complete color lookup table.
That is, when we apply this lookup table in a photo, the black RGB (0,0,0) in this photo will turn into dark green RGB (10,21,9).
Just like Liu Bai said, this is a math problem...
A little more popular
You can just regard LUT as a filter and use it as a filter. The most common area of 3D LUT application is in the video field, because it is a lookup table that relies on mathematical models, so renders faster and can quickly render the colors and exposure of videos.
When shooting videos, they usually use Log format to shoot, so that the picture after shooting will be very "gray", and the advantage of gray is that there are enough details recorded. This is a bit like the RAW format when we took photos, although RAW is far less gray than Log.
For example,
This picture was created by me using ordinary RAW format pictures to imitate Log format. It can be seen that the picture is gray, and the highlights do not overflow the dark areas have details. Isn’t this the basic standard for a good photo in people’s eyes? However, when you look at this color...
And the picture below is the picture after applying LUT from the picture above, with rich colors and better appearance.
Although the color is still not what I want...
This is the skill of LUT, which can output video works efficiently and quickly, but for us who don’t shoot videos, it is more used in the field of images.
has talked so much, so how should it be used?
1. Photoshop
Open the picture in Photoshop. Of course, if you want to get the original "movie feel", recommends adding gray photos to the photo in Camera RAW first, that is, reduce the contrast, reduce highlights and white, and improve shadows and black.
Click the button in the lower right and select "Color Search".
and select the 3D LUT file you want.
Some friends will say, what if the one you bring is not enough? It doesn't matter
, Photoshop supports manual addition. Just find Presets\3DLUTs in the Photoshop installation folder and throw the LUT files you have collected from the Internet into it.
2. Strong photo editing
talks about how to use it on a computer, so can the mobile phone be used directly?
Among all the mobile phone photo editing software I have used, only the bold photo editing currently has this function.
After introducing this function before, some friends were asking me how to use it. Here I will take you step by step.
First, use the computer to send the LUT file to the phone. Any software you can use, for everyone’s convenience, we will use WeChat here.
can be found to send it to any one.
It should be noted that LUT files have multiple formats, including .cube, .look, .3dl, etc., and the sturdy photo editing currently only supports .cube format files.
download and save the file on your phone, click "Open with other applications" - "Save to "File" - find a folder at will, and then click "Add".
This is the save method for iOS. On Android, you only need to click to save, and the file will be automatically stored in tencent/MicroMsg/Download.
Immediately afterwards, in the bold photo editing, open a picture, find the LUT function, and click "Select File".
Click to browse and find the received file just now.
The job is done~
can also adjust the intensity
Since we know how to use LUT files to color photos, can we make some of our own LUT files?
The answer is yes. There are many software for producing
3D LUT. LUTCalc, 3D LUT Creator, etc. are tools specifically used to make such files. However, since our protagonist today is a bold photo editing, let's use bold photo editing to tell you how to export a LUT file.
is much more convenient and quicker to make than other software, but it may be slightly less accurate, which is also inevitable.
Adjust the picture
After opening the picture, adjust the picture and use your usual photo editing process.
Export 3D LUT
After adjusting in the direction you want, you can export the LUT file.
What, can't find this button on your phone? By the way, one thing to note is that the current version of mobile phone version does not support exporting LUT files...
is like this when clicking on the phone... There is no export button...
No, don't hit me, I still have a solution...
After the phone is adjusted, click the picture export button in the lower right corner.
This is not a choice to export the picture, but select "Save Edit as Filter" - "Save to My Filter".
Then open the web version of the stingy photo editing (http://www.polaxiong.com/editor), log in to the stingy account that is consistent with your mobile phone, and you can synchronize the filters you just saved. After
is synchronized, you can export it according to the above steps. Find a picture at will, put the filter you just did, and click Export.
When you click to export, you can see the preview of the LUT on the video.
When you see this, you will surely have many friends who complain that they are exporting them using computers. It’s better to just use PS to adjust the color directly.
is a misunderstanding. we can export LUT files and synchronize the colors we want in different software. After exporting them from the sturdy ones, it can be applied to Photoshop's photo editing and color grading, or it can be used in Da Vinci's video color grading, etc.
In addition, when others ask you for a preset, you can directly export a LUT file and throw it to him, so that he can only see the final result, and there is no way to steal your color grading process through steps. This is also difficult for ordinary filters to do.
Finally, give a few small Tips:
1. Before using it, gray the picture (set log, or manually), which will have better effect
2. After using LUT, it is recommended to adjust it again
3. Multiple LUTs are superimposed and you will get unexpected effects
4. You can even export the filters that come with harshness as LUT to other softwares to use
Justice may be late, but benefits will never be available.
Benefits 1
I have prepared a lot of LUT files for everyone. Now there is no need to worry that I can’t find a few useful ones on the Internet.
official account backend reply "LUT" to get
benefits 2
is still a benefit prepared by Mao Buzhen and Photo Revising for everyone.
This time, you can share your mobile phone photo editing tips in the message. The top two likes will get a premium annual membership worth 149 yuan provided by the slap photo editing~ (the event ends until May 25)
