With modern, digital SLR cameras, having a memory card, or even a few, is essential so you have enough space for your high-quality files to be stored. To make sure you do not run out of storage, and if you don't want to have to scan and delete any pictures or video footage until later on, having a spare memory card is always useful so you can just pop it into your camera and carry on capturing images. Memory card readers offer a quick way to upload your photos to your laptop or PC without any extra cables and it'll save you a lot of time.
If you want some more gadgets for your camera, DSLR camera bags are a must have for budding photographers to keep your gear in one place. It's also worth investing in a few tripods so you can get the consistently framed, steady shot you're after. If you feel like you want to back up what is on your memory cards, then a hard drive would be an excellent solution so you don't have to delete anything you've snapped. And, to display your photos, why not get a digital photo frame for something a bit different.
