What's the difference between indoor photo and outdoor photo?

First of all, the machines used are different. Domestic indoor photography is generally done with a domestic 750 camera, and the sprayed pictures are generally not waterproof (unless sprayed with waterproof materials) and can only be placed indoors. Outdoor photo generally refers to weak solvent ink, and the sprayed pictures are waterproof and can be used outdoors.

Extended data:

According to different uses, inkjet printing can be roughly divided into two types: one is outdoor advertising screen output, and the other is indoor advertising screen output. According to the types of ink used by inkjet printers, it can be divided into: water-based ink, weak solvent ink, solvent ink and UV ink; Water-based ink-jet printers, also known as photo printers, are mainly used for indoor picture output, while weak solvent ink-jet printers, solvent ink-jet printers and UV ink-jet printers are mostly used for outdoor picture output. All three inks have the characteristics of anti-ultraviolet (outdoor fading).

For indoor use, the output picture is generally only a few square meters in size. Limit the maximum width at one end 1.5m ... After the output image is completed, it is necessary to cover the film (guests can choose light film or split film) or board the finished product. High output resolution and clear color saturation. Outdoor accuracy will be relatively small, the size is not limited, and no film is needed.

Generally speaking, the photo resolution is 72DPI. If the image is too large (for example, the file size exceeds 400M when the actual size of the new image is displayed in PHOTOSHOP), the resolution can be appropriately reduced and the file can be controlled within 400 m. ..
