DPI, or Dots Per Inch relates to the dot density when printing. To help better understand the relationship of DPI to pixel dimensions, take an 800x600 pixel image for example: Using 300dpi, an 800x600 image will print 2.6x2 inches. Using 200dpi, an 800x600 image will print 4x3 inches. Using 100dpi, an 800x600 image will print at 8x6 inches. Notes: As ...

I have one. You're right — it's a good value for the money, and there's basically no catch except that if you're running under Mac or Windows you'll need to know a little more about what you're doing than you might if you just bought one of the big-name devices. That's because there's only software for Linux. If you are using Linux (any modern ...

I guess there isn't much more I could say other than I own the Apple CinemaDisplay 30" LCD screen, and I am a heavy duty Microsoft/.NET developer. I work entirely in Windows 7 on my custom-build PC (not a Mac), and this screen has been great. I purchased it quite a number of years ago, and it is still running strong. If I was in the market more recently, I ...

LCD displays actually use several different technologies. You can choose TN (cheap, crappy), IPS (expensive, looks great), or VA (in the middle). If you can afford it, choose IPS. The most important advantage for photographers is that you don't get color shifts depending on viewing angle; IPS displays are also much easier to calibrate well. As a ...

DPI stands for Dots Per Inch. It's used to descibe the output resolution of printers, and it's also often used instead of the PPI (Pixels Per Inch) unit, which is more appropriate for describing the resolution of computer screens, scanners and image files. So, a printer might have a resolution of 2400 DPI, but that doesn't mean that you can print an image ...

Adobe Photoshop Lightroom does. It has since version 4.3 released on December 13th, 2012(it was also in an earlier RC). What are you actually looking for is support of HiDPI, which Lightroom 4.3 and above has. Adobe also updated Photoshop CS6 to version 13.0.2 which supports HiDPI displays. (Note that this does not apply to Photoshop Elements, for which no ...

As of March 2012 nothing like this exists in the color e-ink picture frame market. The Mirasol display made by Qualcomm is the only color e-ink display that I have heard of. I suppose one could try to tap into that reader to turn it into a picture frame style display, but from what I can tell they do not offer it prepackaged that way. The original question ...

Articulated displays are just another moving part that is not typically necessary on pro grade equipment. Adding a screen like that will likely increase the size of the camera, and also make the screen more vulnerable to damage and wear. Some pro series cameras also now have options for external LCD screens that can be attached to the body. Many ...

This is not that hard to do by hand but it is labour intensive. The process is roughly as follows: Take the original still photograph and extract the subject (the model) to a new document Fill in gap in the where the model used to be, by hand or using content aware fill. Warp or texture map the now empty background image onto the inside of a cuboid Add ...

None exist currently. There is one or two chinese made e-readers that have "photo frame" capabilities, (the kindle has this as well, but it is a hidden feature), but these are all limited to displaying the images in grayscale. Color e-ink photoframes are pure speculation at this point. If you are the DIY person, you could conceivably find one that is ...

It's not very hard to take a good photo of an LCD or CRT screen. I'll add oscilloscope in here as a special case of both as I've taken meany such over the years. A few pointers. Some of the following may sound complex at first glance but it's all fairly intuitive taken a section at a time. Shutter speed is critical for a frame-refreshed device due to the ...

VersaTile is getting ready to fundraising for an eInk Digital Picture frame on Kickstarter (you can follow the updates from @getversatile on Twitter ). I think that color eink technology (and black and white, for that matter) is finally to the point where you could conceivably make one of these frames work--200dpi is higher than the retina display on an ipad ...

You could install the Magic Lantern custom firmware which is now supported on the Canon 60D. In addition to being able to load up custom safe area masks which simply display directly onto your LCD, there are a whole host of other video-related features (zebra stripes, anyone?) and functions that aren't included with the native firmware. The only potential ...

Draw the desired shape on an adhesive LCD protector and stick that on.

There are at least two types of LED displays. As explained by @Pete, a normal LCD-display with LED back-light instead of fluorescent tubes / strips. This is the kind you'll find in stores today. Displays with Red-Green-Blue LEDs without the "LCD" part. Sony just released TVs with this technology. It's comparable with OLEDs in that both generate the colours ...

Normally you would use sRGB mode. It is the most common denominator. Keep in mind that this mode is not calibrated, so your sRGB colors will be different from other sRGB colors. They should be closer. Once in sRGB mode your monitor may not be able to show colors which are outside of sRGB color-space which is why sRGB is not the default mode. The truly odd ...

For the last 2 years I've been using a Dell Studio XPS 16 (with Windows 7) and in terms of image quality it's far and away the best computer screen I've ever used. Although this model is no longer available to buy new, I'm sure there are comparable models. I wouldn't hesitate to buy the same again, although it does have some drawbacks. Specific pros and ...

Apple is not the only manufacturer who provides the option of glossy monitors. Because you see rows of iMacs in the Apple store with glossy monitors does not mean Apple is the only manufacturer who provides them. Also, not all Apple monitors are glossy. Pros for Glossy Monitors Higher perceived contrast and saturation. This is a two-edged sword. The ...

Contrast ratio is the ratio of intensity between the darkest point the display can make and the brightest. In a dark room, the bright white spot will be 1000 times brighter than the blackest pixel on the 1000:1 ratio or 900 times on the 900:1. From that stat alone, the Epson has an advantage, however that also isn't the only stat you need to look at. ...

From my experience of buying and operating similar projectors for a camera club in the past I'd start out by saying the factors and figures you need to consider are not the ones they usually sell projectors on, and certainly applying bigger=better may not be appropriate... Pitfalls Most projectors are not sold or built for displaying photos, video is ...

Considering that an average monitor has about 6-bit per channel color depth (8 bit minus the dithering), I guess 10-bit is for color proofing/professional DTP/digital cinema. And higher than 8 bit per channel has another challenges: Video card: the video card needs to support color outputs more than 8 bits per channel. Considering that DVI supports only 8 ...

Look for non-TN screens (twisted nematics), best PVA/MVA or IPS. They are not that expensive today and display gradients better than the (gamer-)fast TN. Take into account that a glossy screen (like the Apple one surely is) might display the pictures more vibrant BUT will be difficult to use with any glaring lights, first and foremost the sun. Maybe even ...

The 90 series from NEC is the benchmark for color-accurate displays. They are simply amazing, color-calibratable displays with wide-gamuts and excellent coverage of color-spaces like sRGB and AdobeRGB. Depending on desired size and budget you can get: Multisync LCD3090WQXi - 30" - That is the one I have and love it. According to NEC, I was the first one to ...

CES 2012 brought some good news here. Kyobo Mirasol is an Android-based device with a 5.7" Qualcomm's Mirasol e-paper screen. A review finds it very demanding on viewing angle though. Ectacto jetBook Color Deluxe, an e-reader with 9" color e-ink display, won the innovation award of CES 2012. The software is proprietary, but according to manufacturer, it ...

Great monitors like the NEC ones have been mentioned so far (+1 for the sync LCD2690WUXi2 for example), but if you are on a "budget", look at some Dell monitors too. I bought a Dell Ultrasharp U2711 recently and I'm pretty happy with it. It's solid: IPS panel, 2560 x 1440 resolution, 16:9 aspect ratio, factory-tuned AdobeRGB (96%) and sRGB modes. Got some ...

The only sensible thing you can do is to calibrate your monitor and work your images with respect to how they are intended to be displayed. The problem is that there is not one way for monitors to be miscalibrated. An uncalibrated monitor will simply give different colors. Different uncalibrated monitors are likely to give different colors and the magnitude ...

If I am understanding you correctly, it sounds like you are taking a photo with the aperture set to less than the smallest f/ number possible for the lens. When you use a smaller aperture (larger f/number) then the image is darker and the depth of field is bigger (resulting in a sharper background). When you look through the viewfinder, the aperture is ...

The file is a 1.5 MB GIF file using LZW compression and contains 84 images. To say that it is made from a "single shot" is misleading at best. You can clearly see 3D relative motion of the model against the background. In a "single shot" all the information that is visible in only some of the images would not be available at all. So the creator has either ...

liquavista are probably closest to a commercial color e-ink display. BUT it's probably not going to be 24bit color any time soon - it's difficult to think of a way of having an e-ink type display with enough gradations in brightness.
