The reflection on the screen tells me you used a flash. The flash only lasts a very short time (at most 1/200 of a second), while the shutter was probably open for a much longer time (maybe 1/30 of a second). Since the frame of your CRT as well as the wall behind it do not emit light on their own, their appearance on the photo is mainly due to them ...

The main reason is that it is low powered. An raster LCD - color or not - requires much more power and most of them need a permanently on back-light. New OLED display do not need the back-light but still pull more power than a segment-based LCD which has much fewer electronic circuits. Most current top-plate LCDs mirror what is shown in the status line of ...

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 distribution),...

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 ...

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 many such over the years. A few pointers. Some of the following may sound complex and daunting at first glance, but it's all fairly intuitive taken a section at a time. Shutter speed is critical for a frame-refreshed ...

Projector native resolution needs to be taken into account. This will often be no higher than about 1024 x 768 in cheaper or older projectors. If you drive it at higher resolutions or at different aspect ratios it may convert internally but you are at the mercy of its processes. A very major and often overlooked factor in using a projector is that what you ...

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 ...

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 ...

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 ...

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 ...

In order to use the rear LCD to compose pictures (as opposed to using the optical viewfinder), you must put your camera into "Live View" mode. On the 600D (and all other recent Canon SLRs), this is done by pressing the button marked with a camera icon and a red dot which is just to the right of the viewfinder: It is worth noting that using the rear LCD ...

Segment LCD is a technology with the lowest power consumption of all available display technologies and those are more than visible on sunlight or any kind of strong light without any need for background lightning (except at night). Very useful for battery operated devices. It's also the cheapest possible display technology. They are also extremely robust. ...

This really depends on what you mean by "touch screen" and "image editing" as well as your own workflow and efficiency. I've been a Photoshop user for more than 20 years. I could use a Cintiq or other touch screen option IN ADDITION to a desktop/laptop to see directly on the drawing surface what I'm working on. However, the many 2-in-1 options are very ...

Check how the image review time is set on your camera. It sounds like yours has somehow been set to Off. These are the instructions from p.60 of the 70D manual: If you set Hold, the image will be displayed for the same amount of time you have set for auto power-off.

The tool displaycal-profile-info, part of the DisplayCAL package, can do this. This works (and works basically the same way) for Windows, Mac, and Linux. See for example for my (calibrated) ThinkPad screen: ... which has a 60% coverage of sRGB and 43% coverage of Adobe RGB.

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 ...

I have an HP Envy touchsmart, so laptop with touchscreen. I'll be honest I find the use of the touchscreen a hindrance/gimmick rather than useful: It's not overly accurate (plus compare the accuracy of your fingertip over a stylus). You spend your life cleaning it. With an actual laptop, rather than tablet/laptop hybrid, it's not that easy to use as they ...

There is no "standard" picture aspect ratio in photography, only some common ones. 35 mm frames are 3:2. Old TV was 4:3. HDTV is 16:9. The way to pick the aspect ratio is to consider what the picture will be displayed on. If it will mostly be seen on a TV, then 16:9 is a obvious choice. If you will make a poster and hang it on a wall, then you can ...

What, exactly, makes them complain about poor picture quality? If you're shooting an uncalibrated projector toward an arbitrary projection surface, you've got a lot of things working against you. First of all, your color configuration is liable to be all over the place. Secondly, you're going to be at the mercy and the reflectivity of your wall. I'd ...

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 ...

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 ...

It is not that the display switches to viewfinder after some seconds, it is that the camera goes to sleep mode. So you need to go to Menu, then look for the Auto Power off option, and choose the timeout value. You can switch it off entirely, which means that your camera would never go into sleep mode, you'd have to manually hit the OFF switch to switch the ...

There is no specific standard, but there are a few aspect ratios that turn up a lot. Currently the 16:9 (1.77:1) ratio of HDTV (1920x1080) is probably the most common. Both 4K (3840x2160) and 8K (7680x4320) video also use the same aspect ratio. It is very likely that when someone references a widescreen TV this is the aspect ratio they mean. Some widescreen ...

So, how do one take photos of items inside display case? A circular polarizing filter will help you reduce reflections. You don't necessarily have to push your lens up against the glass -- just getting closer will help to reduce the reflections. Avoid having a strong light source in line with the camera, either behind you or on the camera. Don't use on-...

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 ...

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 ...

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 ...

The effect is created due to you rotating and the lines being drawn from top to bottom and your shutter was open long enough to capture all lines being emitted. How did the image get skewed that way? You're rotating clockwise and when the flash went, a line at the top of the lower quarter of the screen was being emitted. Then you captured the next line when ...

It's purely a matter of opinion, unfortunately. My own suggestion would be that matted prints always look better than simply framed prints, and some more so with a double mat. I typically go with one solid white or black mat for black and whites with either a black or white frame and for color, go with complementary colored mats and frames that complement ...
