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 photos of 10x15 cm in size, at least 2 megapixels is required, which corresponds to a resolution of 1712x1200. Regarding the creation of small photos of 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 beat competitors' products in terms of megapixels, offering models with 5, 8, 10, 12 megapixels, although only 5 megapixels are usually enough for instant cameras.
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. On a memory card, you can save not only pictures, but also videos.
