What is the size ratio of a normal size digital photo?

There is a 3:2 option in the size setting of the digital album, and if you choose this, you can have the same ratio as 5 inches and 6 inches.

All other options are printed with panoramic 6-inch **, i.e. 4D**.

Not too good, a little wrong.

1. What are the sizes of washing**?

2. Generally, what is the size of the closed film that we wash?

3. Washing ** is generally a few inches.

4. What is the size of the general ruler wash?

1.According to the current standard of ** size, there are strict regulations: 1 inch, 2 inches, 5 inches, 6 inches, 7 inches, 12 inches.

Generally, a 5-inch household wash is enough.

The size of this piece is calculated according to the length of its long side, for example, the size of the 5-inch ** is inches=, and then up, that is, 6 inches, 7 inches, etc. **The aspect ratio is generally close to 3:2.

The general ** resolution is 300 dpi is 300 pixels per inch, according to this, you can calculate how many inches ** how many pixels are needed. (Don't you want me to teach the Pythagorean theorem, right?) ）

Generally, digital print shops use a resolution of 300 pixels for normal processing. Take the usual 6 inches** as an example, the size is 6 4 inches (cm), and the number of pixels according to the standard flushing requirements is 1800 1200 (6 inches 300 pixels inch 1800 pixels; 4 inches 300 pixels inch 1200 pixels), total pixels 6 * 4 * 300 * 300 = 2.1 million; A normal camera will do the job. However, large photos of more than 10 inches are limited by the total pixels of general digital cameras, for example, if a 4.6 million pixel camera needs to be developed for 10 inches, it cannot meet the standard 300 pixel inch requirements, and only 240 pixels can be processed.

However, the relative visual requirements of the first mate are not as high as the small **, so generally use 240 pixel inches, or even 200 pixel inches or lower, the general principle: 300 pixels or less, try to use the highest pixels that the camera can produce. Since digital photos are generally cropped before processing, if the camera memory card is not too small, try to shoot with high resolution, so that the total pixels will not drop after cropping, which will directly affect the clarity of the photo.

It is best to adjust the number of pixels according to the comparison table before sending it for processing. Too small affects clarity. Too much size will cause the store to cut it at will, which will affect the aesthetics of the photo.

Note: The best calculation is based on the store's default processing resolution of 300 pixels; Because the store is generally not flushed higher than this resolution due to cost. If the number of pixels of the sent photo is too large relative to the processing size, and the store does not adjust the processing resolution, it will lead to the incomplete development of the photo.

That's so c...

So the maximum should not exceed this reference standard.

Film can be enlarged, provided that your film is free of noise and scratches, and the magnification limit will be larger, generally not more than 40 inches.

The pixels and resolution of digital cameras have completely limited the maximum size that can be processed (provided that it is clear and undistorted, of course, otherwise you can wash as much as you want, as long as you don't mind seeing a dot matrix).

The magnification of film is another matter, in principle, the latitude is higher than that of a digital camera, but there will be no specific data to provide you with reference, mainly depending on the equipment used for enlargement.

5,000,000 pixels effective 4915200, 2560x1920. Washable ** size 17x13, diagonal family contains 21 inches.

So: 5 inches** (3x5), with 800x600 resolution can be a megabeam.

7 inches** (5x7) with 1024x768 resolution.

8 inches** (6x9) with 1280x960 resolution.

1. Although the first two are 14M (the unit is a pixel, referred to as P, the full name is 14 million pixels, 14MP), but the picture quality is different, the finer the picture quality, the larger the storage space, the worse the unit, the good unit is bytes, referred to as B), this is normal. Of course, it must be stored as a high-quality one, especially for the picture quality party, which is especially important.

2. The image quality is selected as fine, the same picture, the more pixels, the larger the storage space, and the 5 million pixel space is smaller than the 14 million pixels.

3. If you want to get a large one with good image quality, choose the first item, with the most pixels and the best image quality.

4. 4320 3240 pixels, if the shot is very clear, press 200dpi, wash 20 inches** no problem. Of course, it can also be washed to a larger size, but the picture quality will be reduced.

Looking at the size of your **, it is estimated that it will not reach that large resolution. Speaking of large resolution, it should be that the focal length is small** and relatively clear.
