measures the perceived image degradation (typically, compared to an ideal or perfect image). Imaging systems may introduce some amounts of distortion or artifacts in the signal, so the quality assessment is an important problem.
Composition maybe?
You can enlarge image in Image Size dialog in Photoshop, Image > Image Size. At top of window you will see current/new size in bytes. When you enlarging images be aware because you can loose quality.
raster graphics cannot be resized without losing image quality
The "iso" control on a digital camera adjusts the image quality. As to why you'd want to...maybe there's enough light to take a best-quality picture at 1/30 second...but the thing you want to photograph has to be shot at 1/250 second. By adjusting the "iso" control to give you a grainier picture, you can use the shutter speed the picture requires.
digital (higher res): more pixels making the same image = larger image and larger file size. Even if the picture is re-sized by software, the file size does not change unless it is cropped or compressed. Compression usually lowers resolution. b&w film (higher res): more grains of black metallic silver in the same size image. This is primarily accomplished by using slower ISO rated film. Not to be confused with acutance (sharpness due to developer/development). color film: same as b&w except bms is replaced by dye "spots".
Image quality, also known as print resolution, is usually measured in DPI-(dots per inch)
Pixel density. The greater the density, the higher the quality of the image.
Mega pixzal
in the number of pixels
The term is "resolution." Resolution refers to the quality and clarity of an image, typically measured in pixels for digital images. Higher resolution images have more detail and appear sharper.
You should look at the specifications of the camera. If you can't find it on the box the specs will be online. Often times the best cctv cameras are MPEG4 resolution, which is the same as a DVD. The quality of a digital image is measured in megapixels. So genertally speaking the higher the number of megapixels the better the picture quality.
A quality photography contains a meaningful content, good image quality (image sharpness etc, and a good composition.
The level of drywall is measured in the bed coat level 1- 5 being the smoothest. written by; Ken Cutway New Image Painting.
When saving an image as a JPEG with quality settings of 100, the image will have higher quality and larger file size compared to saving it with quality settings of 80. The image saved at quality 100 will have more detail and less compression artifacts, while the image saved at quality 80 will have slightly lower quality and smaller file size due to more compression.
For optimal image compression and quality, a JPEG quality setting of around 80-85 is generally recommended. This balance helps reduce file size while maintaining good image quality. Adjusting the quality setting higher may result in larger file sizes with minimal improvement in image quality.
Saving an image as a jpg with quality 100 will result in a larger file size and higher image quality compared to saving it with quality 80. The image saved at quality 100 will have less compression and therefore retain more detail and clarity, while the image saved at quality 80 will have more compression and may show some loss of detail and slight decrease in quality.
A JPEG image loses quality when it is opened and resaved due the compression algorithms. The more an image is opened and resaved, the more the quality can degrade. An image on a disc will not lose quality unless you resave it on a CD-RW. Opening an image to print will not affect the quality.
