(4a)

1. Upgrading the computer’s processing power and RAM to handle the high-resolution images generated by the digital camera and photo editing software.

2. Installing a high-quality colour printer that can produce prints of the same quality as those produced by analogue cameras.

(4b)

(i) The first change is necessary as digital cameras produce images with much higher resolution and larger file sizes than analogue cameras. This requires a more powerful computer with more memory to handle the processing and storage of these images.

(4bii) The photographer should use an external hard disk instead of floppy disk because floppy disks have very limited storage capacity and are vulnerable to damage and data corruption. An external hard disk can store more data and is more reliable for long-term storage.

(4c)

1.) Adobe Photoshop – this is a powerful image editing software that allows the photographer to adjust brightness, contrast, colour levels and make other modifications to the images.

2.) Lightroom – this is a photo management and editing software that enables the photographer to organize and edit large batches of photos efficiently. It also offers tools for adjusting exposure, white balance and other image parameters.
