These occur when two digital medias clash. Pixels can’t take focused pictures of pixels. i.e. a digital camera photographing a screen as above.
This can also happen in print when the registration or offset can miss align, causing a moire type effect, like the rubber duck below.
These are extremely useful on a mac using cmd+shift+4. You will see the cursor icon change to a crop tool. You can now select just the right part of whats on your screen that you need to reference. If you want the whole screen, which is useful for presentations or showing directions with software in a manual, you can use cmd+shift+3, seen above. Screen grabs will only capture the detail of the image displayed. So if its a low res image or pixelated, thats what your computer will capture.
All digital images are pixel based. The amount of pixels in an image can vary from 72 dpi commonly used in web based design to 300 dpi used for print media. The higher the pixel count the sharper or better quality the image is.
So pixelation occurs when an image is being used to big for the space or just is so low res the pixel count is way too low. Then you start to see pixelation like above. The picture actually starts to show how the image is made up in single pixels.
DPI comes very much into play here when scanning an image or photograph. When using the scanner you control the Dots Per Inch. So you could scan an image too low res if you needed it larger, then it would become pixelated. Scanning photographs from books or magazine due to the nature of the way they are printed, in CMYK plates, you can actually see the different colored dots making up the image, like above on the right. When scanning you can help stop this with the De-screening option.
The best way of capturing an image!
RAW files, JPEGs are all at the control of you to what size you need the media to be for youthen to convert into the appropriate file format for your work, such as a TIFF, PNG. TIFFs are great because they don’t compress and slowly destroy an image like a JPEG does. But they create large files, ok for print, but not great for the web as a JPEG will compress the image to your liking helping keep down the digital memory footprint. PNGs are great for using when you need to preserve a transparency.
Using layers in Photoshop and adding an effect to it, you can create textures and colors that are quite abstract to the eye.
WATER THE SOURCE OF LIFE
Below is my brainstorming and research on the subject, typography and visual content. Websites and screen grabs help to show you my path.

Chasing Ice – Jeff Orlowski
The main focus of my designs for these banners was to get you to stop and let your mind wonder. Switching over the animals natural habitats comes in to play here and setting them in new habitats after the world has suffered from the constant changing climate. Be it the glaciers have melted so the once dry desert like terrain for Elephants is now constantly under water. With the huge increase of water now melted changing the weather cycles dramatically, more moisture will be deposited into the environment causing endless rainfall. Or on the other side of the banner the water has all dried up because of increasing hotter summers due to the sun raising the planets temperature year on year. Anyway you interpret it there has been a huge shift in climate and subtly the image hints at the devastating habitat out comes. The banner directly above homes in on the harsh weather and no mans land the elephant now has to roam in as his habitat.
I wanted these teaser advertisements to be mainly type focused because my main banners have a strong visual mind provoking direction. In these adds I’ve taken the two extremes of water environments and incorporated the type to have a direct visual impact keeping it very simple. Layering type and submerging it into the environmental using cut outs, layering, layered effects, cloning and adding detailed photographic effects at the end to further convince the audience “the type is really there” have enabled me to produce a very photo-realistic finish.
