Magnetic storage is what most people think of when they think of computer storage. It is the most popular form of storage for electronic devices and it is also the cheapest. Everything from your camera to phone uses magnetic media. For a very reasonable price you can get multiple gigabytes of space on a consumer disc no larger than the head of a thumbtack. Its portable and easy to use.That comes with a trade-off though; magnetic storage is notoriously impermanent. It is great for short term storage or transferring files from your devices but it will not survive long term storage reliably. External and internal drives are the way most of us store our files on our computers. I use a 2 terabyte external drive for my main computer all my files and photos are kept there and not on the internal computer drive. That drive is roughly the size of a large smart phone and uses USB connectivity.
You can now get 6 terabyte drives although 2TB to 4TB are more common. A good 2 terabyte drive is less than $100 USD at the time of this writing with 4 TB drives around $150 USD. Computers that are a couple of years older have trouble recognizing more than 2 TB drives sometimes so make sure you check your model and manufacturer to see if you can use the bigger drives. For most artists a terabyte is more than enough for a year of images even for digital work. That would be roughly equal to ten thousand 100 MB files.
I swap my external drive with a new one every year or so. I keep the old ones after transferring the information to optical media for more permanent storage. So far these kinds of drives seem to last about ten years before the files show serious signs of corruption which renders most of the information unreadable but I have also had drives that became unreadable in just a year or two. It is always smart to keep important things in more than one place and really important things in hardcopy.
There is a relatively new type of optical storage disc out now made by Millenniata called Mdisc that claim a 1,000 years of permanence. Mdiscs use a rock like material instead dyes to record the patterns on the disc physically marking the disc with the information. These discs are more expensive than standard discs but even if they only last 100 years, the extra price would be worth it. Mdiscs need a compatible machine to use them; they cannot record but will play in a standard machine. Larger companies now offer such machines and compatibility. Mdiscs come as standard DVD’s that hold 4.7 GB per disc and Blu-Ray DVD’s that hold 25 GB per disc.
Set your image quality to Camera Raw or at least Fine this will give you an image at 300 DPI. Make sure the image of the painting fills the view screen. If you don’t own a digital camera, it’s time to buy one. You can get a reasonably high-quality, 24 mega-pixel (18 x 24 inch, 300dpi image) camera for fewer than 800 dollars (at the time of this writing).
I recommend a bank of at least four 48 inch fluorescent or LED daylight bulbs for indoor work. The bulbs should have a CRI rating of 90 or more. I have an article about studio lighting here.
A good image for print ads would be 9 x12 inches at 300 DPI. Most current digital SLR cameras, tablets or smartphones can shoot at that level of detail. The difference is the quality of the image and lens. Obviously a good digital SLR camera has a better lens and sensor than most other devices. It comes down to your budget. If it is another device other than a camera though, Make sure you can attach it to a tripod for stable shooting. If you want to make prints of your work for sale then you will need a better camera that can shoot a larger file.
