Color Look Up Adjustment Layers offer efficient options for altering an image
Have you heard about Color Look Up Tables? They’re a fairly recent addition to the photographic workflow, having been added to Photoshop in version CS6. But the premise behind color look up tables (sometimes called CLUTs or LUTs) has been around a lot longer than that as a method of transforming colors. For example, in the profile adjustment of a computer monitor, or in “grading” the look of film and video, LUTs have always played a vital role. A look up table essentially says “this color should actually be rendered like that color,” remapping one set of colors into another. Converting colorful hues into many grayscale tonal values, for instance, or simply converting one palette into a slightly warmer or cooler version of itself. You can imagine how this would be useful for the wholesale changing of colors, rather than doing it selectively, pixel by pixel, frame by frame, time after time.
The addition of CLUTs to Photoshop’s image editing capabilities is especially useful, though, because with a Color Look Up Table applied to an image as an adjustment layer you’ve got a whole new way to change the entire look of an image without permanently affecting a single pixel. That can be a subtle adjustment (like a warmer image with lower contrast) or a total off-the-wall overhaul (like a color negative or cross processing effect). Color look up tables as adjustment layers become, essentially, one-click picture styles that can do really great things for your photographs—and your videos. And because the changes are made on an adjustment layer they can be easily modified, masked and even eliminated without affecting the pixels on the layers below.

Great article in the Economist Magazine
It is getting ever easier to record anything, or everything, that you see. This opens fascinating possibilities—and alarming ones
ABOUT halfway through Dave Eggers’s bestselling dystopian satire on Silicon Valley, “The Circle”, the reader meets Stewart, a bald, silent, stooped 60-year-old who has “been filming, recording, every moment of his life now for five years”. Stewart is the first of the novel’s characters to make all his actions visible to anyone with a computer who cares to look—the first “transparent man”.
Cathal Gurrin, a computer scientist at Dublin City University, is not quite that transparent. But to those with access to his archive he is pretty see-through. Mr Gurrin is a “life logger”, someone who thinks that if, as Socrates claimed, the unexamined life is not worth living, the life which is digitally recorded with an eye to potentially endless re-examination will have much to recommend it. Patterns in their data, they hope, will reveal opportunities to be healthier, happier and more effective.

Designers love their software. From using Gimp to Photoshop, designers spend hours crafting on the computer. Unfortunately, many designers neglect an important design tool: sketching by hand with pen and paper. Drawing by hand can bring clarity to the design process and help designers generate ideas, get organized, and visualize their concepts.
Additional Tips for Using Pen and Paper
As you develop your design on paper, here are a few things to keep in mind.
- Sketch, don’t polish. Keep your designs rough and unpolished on the page. This makes it easier to scrap ideas, start over, or make changes without feeling like you wasted time. Use your pen and paper to design, use your software to produce.
- Embrace chaos. Let your ideas flow freely from your brain to the page. Don’t worry about keeping things neat and tidy. Focus instead on getting your ideas down and organized.
- Don’t be afraid of mistakes. If you make a mistake, embrace it. Draw over it or write yourself a note, but don’t scrap the entire page. Look for ways to innovate with your mistakes. Sometimes great ideas are born from mistakes.
- Carry your designs with you. Keep your sketches and ideas in a notebook and take it with you when you go places where you might have new ideas. You never know when an idea will hit you.

The thing that you need to know in choosing icons for your web design is that you need to be understood and purposive. You have to be so universal that even a simpleton will understand you. You have to apply the purpose and try to achieve it in your design. A great web designer does not stop just because he is tired of looking for good icons. A great web designer will just stop, when he sees it in the website.
Truly, small things tend to have greater roles and those bits of facts can mean a great deal of inspiration. And I bet the icons agree.
Icons should be appealing and readable
They should be universal
They should be consistent
It should complement with the motif
They should be functional

A full HD smartphone isn’t cool. You know what’s cool? A Quad HD smartphone — one with 2,560 x 1,440 pixels, like the one China’s Vivo just announced.
The Vivo Xplay 3S will be the world’s first smartphone with a 2K HD screen, with more pixels than a full-size iPad. The company didn’t specify exactly how big the display would be, but Engadget suspects Vivo is using a 5.5-inch Quad HD panel made by LG. That would translate to 538 pixels per inch (ppi).
So why would you want a phone with so many pixels? After all, if Apple’s “retina” claims are to be believed, once you go north of 300 ppi, there’s essentially no benefit — the human eye can no longer discern individual pixels at normal viewing distances. Screens that are already 1080p, such as those on the HTC One, are far beyond “retina” resolution. Why go even further?
