Hmm, I heard that Suji wants to wants to become a professional photographer? Since she has to take lots of high quality pictures, as well as giving them to clients... I guess she would need to use a Camera (of course...), a monitor and a USB!
Well, reasons for this is because firstly, if you want to take photos, you should use a camera. There are actually no other options. Also, after using the camera, you need to look at the photos close up. So you would need to transfer the data of the camera to the USB. USBs can carry large amounts of data, so it would be useful when you hand it in the the clients too.
After transferring the data into the USB, you would need something to view it with, so you would need a monitor! So that's the reasons for needing a camera, monitor and USB. I hope it helps!
