Are pixels all the same size?

Are pixels all the same size?

Pixels are not always the same size from device to device. You would have the same number of pixels and the same image, just the pixels are a larger size.

Why are some pictures more MB than others?

JPEG is a compression format, so large parts of an image that are the same color will be reduced to small amounts of information. Raw is literally the raw data off the sensor, so it’ll be the bit depth for the number of photosites on the sensor, no more and no less. Now it only takes 11 bytes.

Why are same resolutions different sizes?

Image resolution is determined by the total number of pixels located within the image noted as pixels wide x pixels high. They are the same size in dimensions, but their file sizes are significantly different, because the image on the left has much more information, or pixel variation than the logo on the right.

Why are pictures different file sizes?

JPEG compression says how much details to throw away, not how much to keep. With the same amount of details thrown away, two different images will be left with different amount of details. The storage is generally proportional to the amount of details left in the image after compression.

Why are pixel resolutions in even numbers?

Easier to Scale. Make retina assets, sprites, font sizes, etc., divisible by two, it will make scaling down a lot easier. By keeping the dimensions and distances in even numbers you prevent displacement of pixels when the image is being down-sampled by the browser (and the downscaled version remains pixel perfect).

Do different images have different file sizes?

There are three main factors that determine the size of an image file: pixel dimensions; image format; and colour depth. This refers to the number of pixels in an image: the more pixels that are present, the larger the file size will be.
