In this lesson we will be discussing the Measuring Tools within Adobe Photoshop. These are also found within the left side vertical Tool Panel of the UI.
In the red circle on the left side of the UI you will find the most commonly used measuring tools. This one is called the Eyedropper tool. As with many of the tools in the Tool Panel, there is a little arrow in the bottom right corner of that tool. When you click and hold it down, a pop-out menu will show up and give you more choices as to what tools you can choose from and use.
Photoshop Eyedropper Tool
Select the I key to quick select it. Select Shift + I keys to scroll through the pop-out menu.
The Eyedropper Tool is used to quickly sample colors from an image within Photoshop. It’s a very convenient tool to use as you are painting or editing a photo as you work. If you have the brush tool open, press the ALT Key on Windows or Command on a Mac. Select your desired color from the image you want. A little color wheel will come up around your cursor. The bottom half will be your old color and the top half of the wheel will be the new color you just selected. Release the Alt or Command key and go back to painting.
This makes for a much quicker and easier work flow.
Photoshop 3d Material Eyedropper Tool
This is the 3d Material Eyedropper Tool found within the pop-out menu from the eyedropper tool. This is a really fun tool if you are using 3d objects. When you either create or import a 3d object into Photoshop, you can color the object with some of the installed textures within Photoshop. Some of these textures have multiple colors in them to give a textured look. Say, for instance, you have a brick wall, your object is going to have the appearance of a real brick wall that reacts with light and shadow the same way a real brick wall would.
So, you can take your 3d Material Eyedropper Tool and use it on the 3d object that has whatever color or texture you have placed on it. Then you can take your cursor to another 3d object and, using the Fill Bucket tool, (also found in the left side Tool Panel that we’ll get to later) left click your mouse and the new object automatically fills with the exact same color and texture as what you previously selected.
Again, this tool is a lot of fun and makes your workflow quicker and easier.
Photoshop Color Sampler Tool
With the Color Sampler Tool you can select a color from your image. The number 1 will appear on your image. You can select up to four color samples. Each of these selections will show you the color code for that selected color.
Here is a video which goes through the Color Sampler Tool as well as the Eyedropper Tool:
Photoshop Ruler Tool
Using the Ruler Tool, you will not have a printed line on your image, but just a line that is there for the moment while you measure. The options bar and info panel are where you will find the different information being displayed about your ruler tool as you use it.
The Ruler Tool can help you straighten your images out just by placing the Ruler Tool between two points and clicking on Image Rotation/Arbitrary. This will straighten your image out no matter how angled it is.
Photoshop Note Tool
Adding notes to your document is easy with the Note tool. Click and hold down on the Eyedropper Tool in the Tool Panel to access this tool.
Once you have the Note Tool selected you will be able to click anywhere in your document and leave yourself notes. The Notes Panel will open up on the right side of your screen and you will be able to write anything you need for keeping records. Notes written in this way can be saved in Photoshop (PSD), PDF or TIFF formats. Saving in this way, you are providing a way for yourself and others to be able to open up this file in Adobe Acrobat, Adobe Reader and Adobe Preview.
In order to delete any or all notes, simply press CTRL/right-mouse-click on the note icon. You will have the option to delete just that note or all of your notes.
I’ve included a video for better understanding for this as well!
Photoshop Count Tool
Adobe Photoshop has a method of being able to count objects in your image. This method is with the Count Tool. The Count Tool is found at the bottom of the pop-out menu from the Eyedropper Tool.
You have the option of counting groups of objects or an object at a time.
Here is a video to help you with understanding how to use the Count Tool.
So, now you know the different measuring tools within Adobe Photoshop. You are on your way to creating something really great and unique! Hope this post has helped you understand these tools better so that you are able to create quickly and effectively. Because I know how fast some things can come through my head and I want to get them out on canvas as quickly as possible. These tools will help you achieve that better.
