How to Use the Crop Tool in Adobe Photoshop
The crop tool in Adobe Photoshop enables the designer to cut a picture, to a size of their choice. Cropping is not just limited to reducing the visible size of an image, but also has certain features which allow the user to rotate the image before it is cropped, giving it a different angle. Cropping an image becomes vital at times when you need to use only a certain part of the image. Here is how you can use this tool on Adobe Photoshop.
- When you open Adobe Photoshop to a new file, this is how it appears on the screen. Towards the left of your screen, where you find all the tools for Editing an image on Photoshop, locate the third icon, which is the crop tool for Adobe Photoshop. Now there are chances that the icon would be slightly different because of the default settings for Photoshop. But don’t worry, you can always click the right button of your mouse which will open a dropdown list of tools for this specific tool. You can use these tools to crop your image and also adjust the perspective of your image.
Accessing the Crop Tool from the toolbar on Adobe Photoshop on the left of the screen. 
The dropdown list for this tool shows different cropping tools which can be used by the designer. - When you press the crop tool icon that is towards the left of the screen, and then tap the image or the layer that you want to crop, these borders will appear on the artboard.
The cropping borders that appear on the image. - All the corners of this frame and the sides have bars on them which can be dragged to crop the image. These bars help you decide what part of the image you want to keep and what part of it you want to be removed.
All of these bars can be used to increase or decrease the size of the cropping area - Once you have dragged in or dragged the crop bars out, you can click on the tick arrow that is point number 2 in the image below.

Cropped image - Once your crop bars are still showing on the image, and if your bring your cursor towards the corners of these bars, you will find a cursor which is a bit curved, something similar to the arrow that I drew in the image below. This arrow can help you rotate the image that you want to crop.
Rotate the image according to your design on Photoshop - For a better understanding of the previous step, I added a few shapes to the layer so that when I rotate the image, the change is visible.
I drew a pattern so that when I rotate the image it is visible I rotated the image after drawing the shapes and this is how it looks now.
