What software does the studio need in the later stage, PS, AI or crowldraw?

Photoshop software is used for the O-diagram in the later stage of the studio.

Photoshop's specialty lies in image processing, not graphic creation. Image processing is the editing and processing of existing bitmap images and the application of some special effects, with the emphasis on image processing.

Both AI and coreldraw are vector drawing software, which can design the original image format without sawtooth under the condition of infinite enlargement and reduction of the image, which is quite convenient for product design, poster printing, exhibition drawing, graphic design and so on. Generally speaking, coreldraw is more suitable for Logo design, and illustrator is more suitable for UI, AI, interruption and artistic visual creation.
