Sensor resolution
The resolution of the matrix determines both the final image quality and the size of the resulting images. To create high-quality, legible photographs measuring 10x15 cm, at least 2 megapixels are required, which corresponds to a resolution of 1712x1200. Regarding creating small photographs measuring 6x9 mm, a 0.8 megapixel matrix is enough, which is equivalent to a resolution of 1024x768. Note that the number of Megapixels (Mp) today has largely become a marketing ploy. Manufacturers are trying to surpass competitors' products in the number of megapixels, offering models of 5, 8, 10, 12 megapixels, although for instant cameras only 5 megapixels are usually enough.
Picture print time
Printing/developing time is the speed at which photo cards are ready for viewing. The fastest photos are obtained on digital cameras — it usually takes from 10-20 seconds to 1 minute to print one average photo. When working with analogue models, the time for obtaining images increases significantly — on average, the development of an image takes 1-2 minutes. And analogue cameras from the “retro” series can develop pictures for 5-7 minutes at all.
Card reader
The card reader allows you to use memory cards of various formats in the camera. Typically, the card reader supports the following drives: MicroSD, mini-SD and SD. The presence of a card reader is typical for instant digital cameras. You can save not only pictures, but also videos to the memory card.
