There are a variety of methods for cropping but this time I will be using 「Crop tool」.
In Photoshop, 2L photos, hagaki, and also other standard sizes are registered, so it is a convenient function for those who have decided on a size.
Prepare the photo you want to crop.
Select 「Crop tool」 and drag diagonally so as to include the part you want to crop. (This time it is the 2 flowers.)
The part you want to crop is included in the trimming frame.
The part that will be cropped is bright, and the unnecessary parts are dark.
If you put the cursor on the four sides the arrow ⇔ will be displayed, so if you drag, vertical/horizontal/size can be modified.By putting the cursor on the corners of the rectangle and dragging while holding Shift, it will change vertical and horizontal equally for size.
If you put the cursor outside the trimming frame, an arc arrow will be displayed, so if you want to rotate, drag it.

If you move the cursor in the trimming frame, a black ➤ arrow will be displayed, so if you drag, the trimming frame in its entirety will move.
If you put a check in Perspective and drag with the cursor on the corners, the trimming frame can be warped.
In this way, modify the position that you want to crop.
After the part you want to crop is perfectly in the trimming area, click 〇 to finish.
It is also possible to crop by double-clicking inside the trimming frame.
If you select the 「Crop tool」, it is possible to set, like in the above picture, on the control panel, the 「Crop tool」size. If you click the ▼ mark, the fixed size will be displayed, so if there is a size you want to crop to, click that.
If you enter the values for size or resolution within the frame, it is possible to crop sizes besides the standard ones, and for those who have not decided on any size in particular, if you click clear and make the frame display nothing, it is possible to trim to a size you like.
If you click the foreground, the currently displaying picture will display the size and resolution of the left frame.(Retaled Articles:Know More about Photoshop Trimming)
