To execute photo editing, you need to have the following hardware and different requirements.
Here are the required hardware for Photoshop;
Cameras. Before starting in Photoshop, we must ensure we are using the correct equipment to capture our digital images.
Digital Storage. Digital imagery soon takes up a lot of storage space on your computer's hard drive, so other storage option should be considered.

Here are the required hardware for Photoshop;
Cameras. Before starting in Photoshop, we must ensure we are using the correct equipment to capture our digital images.
- Camera Formats- digital cameras are available in a wide range.
- Resolution- digital image resolution is measured in megapixels.
- Compact Cameras- the quality in compact digital camera has greatly improved in the past few years.
- Lens quality- while resolution is important, another aspect determining image quality is the lens.
- SLR Cameras- single lens reflex cameras normally have interchangeable lenses, and some can use optics designed for film cameras.
- Larger formats- some medium and large format film cameras can be used with purpose-made digital backs that can record each photograph at 22M or more.
- Cellphones- Even a 2M camera in a cellphone can produce image whose quality is relatively decent if processed correctly in Photoshop and not enlarge too much.
- Upgrading Cameras- There is often the tendency, encouraged by some camera magazines and, of course, manufacturers, to upgrade cameras as new models are introduced.
Computers. After camera, the most important piece of equipment required for digital photography is a computer. Like cameras, they come in all shapes, sizes, and prices.
- Apple Mac or PC- your choice of computer will probably be determined by the other uses it will be put to, as well as personal references.
- Desktop computers- Today, some desktop computers come with integral monitors, rather than having a separate monitor and computer tower.
- Laptops- despite their small size, laptops can be as powerful as desktop computers, though they tend to be more expensive.
- Processing speed- the computer's ability to perform and process quickly and efficiently is expressed in gigahertz (GHz).
- RAM (Random Access Memory)- when a computer program is running, it uses RAM to process files. RAM is expressed in megabytes (MB) and gigabytes (GB). For digital photography, 256MB is the minimum requirement. However, extra RAM can be bought and installed onto your computer.
- Hard drive- applications, programs, and files are stored on the computer's hard drive, which commonly has the capacity to store more than 80GB of information.
- Screens- though traditional, CRT ( Cathode Ray Tube) computer screens are still used, many people now prefer the slimmer LCD (Liquid Crystal Display) screens, which are standard with laptops. LCD's are more expensive than CRTs but take up lesser desk space.
- Efficient working- when using your computer, work is as much comfort as possible. Invest in a chair that encourages good posture and supports your back.
- Flatbed scanner- these are the most popular and economical, and will scan artwork (photographics prints, book pages, anything else on paper) up to letter paper (A4) size, though larger, professional models are available.
- Film scanner- these are use only for scanning film, with optics designed specially for smaller formats.
- Professional scanners- the best quality of scanning is provided by the drum scanner, which is used by professional reprographic houses. However, they are very expensive.
- Scanning resolution- the resolution you scan at should be determined by the size of the image to be scanned and the proposed size of the finished print. Resolution is measured in pixel per square inch (ppi). 300ppi will be adequate for letter paper (A4) artwork to be reproduced and printed at the same size.
- Dust scanner- when scanning, specially from film, tiny scratches and particles of dust are recorded, which require careful retouching.
- Sharpening when scanning- although most scanners will provide the option to "sharpen" an image using an unsharp, it is best to avoid this. Any sharpening required should be done in Photoshop after all other work has been completed.
- Graphic tablets- many manipulation required careful use of the mouse to draw around areas to be altered. graphic tablets, which comprise a pen and a small tablet, allow this to be done with far more precision.
- CD's and DVDs- these are very useful for storing and distributing digital images. A CD can hold up to 800MBs of data, and a DVD more than 4GBs.
- External hard drives- the preferred method of long term storage is an external hard drive.
- Memory sticks- for temporary storing and transferring files from one computer to another, small memory sticks, which plug into USB socket, are very practical.
