15 inches 15x10 38.1*25.4 30002000 6 million pixels

In addition, digital movies don't care about pixels. They only look at the number of pixels on the long side, 1200 out of 5 inches, 1400 out of 6 inches, 1700 out of 7 inches, and so on.

1 inch (refers to the inch) = 2.54cm
The x-inch we mean is the long side of the photo. If it is 5 inches, it is 2.54x5=12.7cm.
12 inches is 2.54x12=30.5cm
8x12 is the long side 2.54x12=30.5cm, the short side 2.54x8=20.3cm

3R refers to paper, 3R is 89MM, 5R is 127MM
Usually 3R refers to 3*5 is 5 inches 5R refers to 5*7 is 7 inches

R means rectangular (English is Rectangle), all with the shortest edge.

Most of the 135 camera photos are washed into 3R, 4R or 5R or more. If the bottom of the 6X7 of 120 machine is washed into 3R photos, then it will not be "3" X5", and it will be 3" x 3.5 "Inch", this is also a 3R photo, and there must be 3 inches.

Also like the 120 Hasselblad 6X6 at the end of the photo, because its negative is a positive square, if you want to take a positive photo, such as "3-inch X 3-inch", "5-inch X 5-inch", in this situation we do not Called 3R, but 3S or 5S, S stands for positive square (English is Square).

The number of pictures taken by a digital camera is generally 4:3 (consistent with the proportion of our monitors), while the proportion of enlarged pictures is generally about 3:2 (consistent with the aspect ratio of film negatives). Therefore, digital The photo of the camera is enlarged to print the ratio of the photo to 3:2, so that the enlarged photo is just full of photo paper. If your photo does not want cropping, or if the shot is too full and there is no room for tailoring, then you have to leave a white border on both the left and right sides of the print.

For example: Your photo is 1600*1200, ie the ratio is 4:3.
The 6-inch photo is 15.2*10.2, ie the ratio is 3:2.
If your photos are not cropped, a 4:3 ratio photo is placed on the 3:2 photo paper
You can only leave white borders on both sides of the photo, just like the white boxes on both sides (up and down)
If you don’t want to leave white borders, you can cut off some of the top or bottom of the photo.
Make the photo 1600*1074 (1600/15.2*10.2=1074), this is 3:2,
Just filled the entire 6-inch photo paper.

The size of an 8-inch photo is 6*8 (15.2*20.3cm). The ratio is 4:3. Most digital photos are printed without the need for cropping.
