Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail.
Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtense. Line pairs are often used instead of lines; a line pair comprises a dark line and an adjacent light line. A line is either a dark line or a light line. A resolution of 10 lines per millimeter means 5 dark lines alternating with 5 light lines, or 5 line pairs per millimeter (5 LP/mm). Photographic lens and film resolution are most often quoted in line pairs per millimeter.
The resolution of digital cameras can be described in many different ways.
Learn how to correctly choose an image resolution (DPI) for your digital artwork and photography. ► Subscribe: http://bit.ly/1BscNfa If you are new to digital art, one of the first challenges is the Resolution setting that appears when creating or resizing a canvas in Corel Painter. Whether you work in inches or pixels, this video makes it really easy to understand and use Image Resolution correctly when creating images for print and web. DPI = Dots Per Inch (Quantity of dots per inch on a print) PPI = Pixels Per Inch (Quantity of pixels per inch on a device screen) Pixels (Measurement:) A unit of measurement used to define the dimensions and resolution of computer graphics and digitized images. Pixels (Artistic Medium:) Pixels are the smallest component of a digital image. They can b...
In this tutorial, we will explain the theory behind how pixel images work. We will also explain a bit about the crop tool, image size and resolution. More tutorials can be found at http://psd.tutsplus.com.
What's the difference between a high and low resolution image file: And why should you care?
In this video I am going to discuss the difference between ‘Image size’, ‘image Dimensions’ and ‘Resolution’ in Photoshop. As you begin to create in Photoshop, it is essential you are familiar with the concept Photoshop uses to create images. It’s important early on that you are aware so you can create the right work to the right specification. This can be a tricky concept to understand at first, but when you do, you will be all the more confident using Photoshop. Enjoy!

You have this killer image shot in camera and ready to drop into your newest print project. However, the file says it's 72DPI instead of 300DPI. How do you prep this image for a high resolution print project? Fire up Photoshop and I'll show you how in minutes. ____________________________________ LET'S CONNECT: • Homepage: http://digitalhart.com • Facebook: http://www.facebook.com/designlikeapro • Tweet Me:@designlikeapro • Instagram: @nickihart • Snapchat: @nickilhart GOODIES FOR YOU: • T-Shirts: http://digitalhart.spreadshirt.com • Society 6 Shop: https://society6.com/nickihart • Redbubble Shop: http://www.redbubble.com/people/nickihart ______ Business Inquiries: request@multi-designs.com ______ WRITE TO ME: Nicki Hart PO BOX 11794 Pueblo, CO 81001
A brief introduction to the concepts of spatial and intensity resolution in digital images.
Has there ever been a time when you had a low resolution image you want to print? Maybe a screenshot of something or an image where the quality just wasn't there? In this tutorial I'll show you one way you can modify an image and enlarge it to be printed as an 8x10. It only takes a few minutes and a couple of steps. One quick note, I did not create the original image used in this tutorial - I'm not sure who did, but I have seen the image used in various places on the web. Video Summary This particular image was at a resolution of 72 ppi and approximately 5.5" x 6.5". Our goal was to modify this image so it could be printed as an 8x10. When preparing images for print, it's important to keep in mind that your file resolution should be a minimum of 240 ppi to get a high quality print....
How to quickly make low resolution photos look better in Photoshop
In this video, I will show you how to convert low resolution image/picture to 300 DPI (or PPI) with using three different softwares (Gimp, Pain.net, and Photoshop). ----------------------------------------------------------------- Useful Links: ---------------------------------------------------------------- ►Gimp: https://www.gimp.org/downloads/ ►Pain.net: http://www.getpaint.net/download.html ------------------------------------------------------- If this worked and helped you ► Do not forget to Like, Comment, and Subscribe ! ================================================= ► To Watch all our videos, click here - https://goo.gl/aCCrzi ► Subscribe to our channel, click here - https://goo.gl/9QCQhC
Well, this trick can be used to get the light sequences as well! Isn't it cool? Give 1000 likes, and I will jump to intermediate image data filtering technique! The greater the image source, the more information you can get out of it!
Resolution is the fineness of detail in a bitmap image and is measured in pixels per inch (ppi). The more pixels per inch, the greater the resolution. Generally, an image with a higher resolution produces a better printed image quality. Same image at 72‑ppi and 300‑ppi; inset zoom 200%. for more: elearningpluse@gmail.com https://www.facebook.com/E-Learningplus-180812565656766/ https://twitter.com/ELEARNINGPLUS3 https://plus.google.com/102870760029215633622 www.e-learningplus.com

The Conundrum of Image size can be intimidating even for experienced Photoshop users and so can resolution, especially resolution for printing. In this video you will learn about both of those topics in great detail. At the time of recording the video, Photoshop CC did not come out yet. And even though the Image size dialog box has changed it's interface slightly, the features remain the same.
In this tutorial Ian Norman shows us how to enhance the resolution of a camera sensor with a technique called superresolution. With this technique, it's possible to mimic the sensor-shift high-resolution mode found on cameras like the Olympus OM-D E-M5 Mark II to squeeze more megapixels out of the sensor. In his example, he increases the resolution of a 24 megapixel photo to more than 90 megapixels.

A technical lecture on understanding image resolution and Adobe Photshop image manipulation techniques using: selection, marquees, cropping, upsampling and downsampling, masking, quick mask. We cut the sky out of the back of the image presented, going carefully around the edges.
The resolution of a microscope can be defined as the smallest distance at which two small objects can still be seen as separate objects. This lecture discusses various criteria for resolution, the factors that influence resolution in the lateral and axial planes, and how to sample an image adequately using a camera or confocal microscope, such that the full optical resolution is retained.
This lecture describes the diffraction of light, a key principle in image formation and a factor that limits the resolution of a conventional light microscope. The behavior of light traveling through an objective is described along with the concept of numerical aperture. The "point spread function" (or PSF) and Nyquist sampling are explained, which are critical concepts for understanding image resolution and detection of images.
In this lecture, held on 3/9/15 at UC Berkeley, Nobel Laureate Eric Betzig, describes three areas focused on addressing the challenges of high resolution imaging: super-resolution microscopy; plane illumination microscopy using non-diffracting beams; and adaptive optics to recover optimal images from within optically heterogeneous specimens.
