Differences Between 1D And 3D LUTs 

The main types of LUT are the 1D and 3D LUTs. While they both alter images, they do so differently. 

1D LUTs:

1. Sees in shades of gray.  
2. 1D LUT can only transform black-and-white levels, contrast, and brightness.
3. Red, green, and blue colors are treated separately on individual channels of the image without interacting with each other.
4. It manipulates images along a single axis or curve.
5. Commonly a file extension of .lut

3D LUTs:

1. Sees in full color as a three-dimensional cube.
2. 3D LUT also changes hue and saturation; hence, colors can be adjusted to other colors. Se
3. It treats the three RGB values together.
4. It manipulates images along three axes representing red, green, and blue.
5. Commonly has a file extension of .cube

Common LUT File Formats

The common LUT file formats are: 

• .cube - .cube is a common 3D LUT format supported by most video editing software and color grading applications.
• .look - .look was developed by Adobe and is mainly used in Adobe SpeedGrade and Photoshop. 
• .3dl - Autodesk developed it, and is older than .cube. However, many video editing apps still support the file format.

3 Tips for Using LUTs Effectively 

Here are some tips to guide you when using LUTs in Photoshop: 

Importance Of Proper Exposure And Color Balance Before Applying LUTs 

LUTs work best with properly exposed images. Hence, if your image is overexposed or underexposed, your color grade process will not yield the best results. 

All colors should appear as they should, and the color values should be consistent. If not, you need to do color correction before you apply a LUT unless you may not see the expected results. 

Using Multiple LUTs For Advanced Color Grading

To achieve a more advanced color grading, you can stack numerous LUTs on top of each other. This process is known as LUT stacking. After using a LUT to adjust the color balance, you can use another one to fine-tune specific colors. 

But, you must be careful and ensure you know how to do it. Because, LUT stacking can create a mess if not done well. So, you should understand the role each LUT plays so you can combine them effectively to create a beautiful edit. Knowing this is important because not all LUTs work well together so they must blend well. 

Choosing The Right LUT For A Specific Image Or Mood 

You must know that LUTs are not one-size-fits-all. Not all LUTs are right for all images, so you must find the right one. You need patience and attention to detail to learn how to use LUTs in Photoshop correctly. 

Generally, consider the mood or style of the image when choosing the right LUT. Experimenting is all important. Try out different LUTs till you find the right one for your image. 

Conclusion

LUT in Photoshop is very crucial in the editing process. It also enhances images by simplifying the color grading process. With a single click, LUT allows you to transform the color and tone of images.
