How to turn off backlight on iphone 4


There is no separate "back light" setting like there used to be on some earlier phones.

In the Settings app of your iPhone, there is a section called "Display & Brightness". You can use that to make your phone's display brighter or dimmer, but as you have probably discovered, it dims or brightens both the foreground and the background elements together as one.

You can turn it all the way down, which is very dim and hard to see in normal indoor light conditions, but may be preferable in extreme low light conditions like in a nightclub setting, or in complete darkness.

Why isn't there a separate back light setting?
To fully answer this, I would probably have get into more than you ever wanted to know about displays.

First, there is really no background or foreground on today's smart phone displays. The foreground elements and background elements we see on the iPhone are really a graphic illusion created by lighting individual pixels with different colors. All of these pixels are on the same plane, so nothing is really behind or in front of anything else. It's just artistically drawn to look that way.

Brightness is simply an "intensity" setting applied uniformly across all of the underlying individual pixels within the display matrix, and has no relationship to color. For clarity, let's look at the difference between lightness in colors, versus display brightness:

COLOR LIGHTNESS is a matter of how much WHITE (all the RGB colors summed, for example) is present in a given color. This has nothing to do with display brightness.

DISPLAY BRIGHTNESS is a matter of how much LIGHT INTENSITY is applied uniformly across all pixels in the display matrix.

At zero display brightness, you would not see white any better than black, blue, green, red or any other color. You wouldn't see anything.

Why did you expect to be able to control the back light?

Prior to the smartphone era, the displays on early cell phones and pagers (and lots of other devices that had displays) had a lighted background that contrasted with dark foreground elements.

The background intensity was a separate setting on those devices, but that's because the background was the only thing that had intensity. The foreground elements were solid black LCD (liquid crystal display) segments that were used to form characters and very simple graphics and lines.

Everything we see on today's smartphone displays is dynamically drawn by lighting different pixels with different colors at different times. Individual pixels on a Retina display are nearly microscopic in size--they cannot be separately discerned by the eye.

Imagine a matrix of microscopic light bulbs, each of which can separately change to any of millions of colors and levels of brightness at any time, on command. Just imagine the sheer number and complexity of possible commands to control a Retina display!

Even if Apple wanted to provide a new feature that enabled us to separately control the perceived "back light", it would only be an illusion as well.

Such a feature would require some sort of complex algorithm to determine which pixels are involved in what you perceive as the "foreground" elements at any given time, so it could add intensity only to those pixels considered to be "background" at any given time.

Since "foreground" and "background" elements drastically change shape (and location) at any time, such a feature would be pretty daunting to implement.

You might be better off using a pure black graphic as your background image if your goal is to have more contrast to make the app icons stand out.

Cheers,

When taking a picture in daylight and the background is bright the background comes out as white-no colour. I've tried fill in flash and also exposure compensation to no avail. Very frustrating-please...


Your camera is setting its exposure to your subject, which if it's darker than the background will cause the background to over expose. You need to set the exposure to the background which then will cause your background to be properly exposed and your foreground or subject to be darker. With a point n shoot camera, accomplishing this might be a difficult task. But if you expose to the background and use the fill flash, you should then get your properly exposed image.

Background is overexposed


So, the problem doesn't seem to be the flash if the actual subject in the foreground is exposed properly. My guess is that the background is being lit by another light source. Typically, your camera uses a flash for dark areas or what it gauges as a dark area. This doesn't adjust the background for additional light sources. For example, if you're standing outside and there's a tree covering someone that you're taking a picture of your flash will adjust to "properly" light that individual. However, because the flash was used for the main subject, the background is actually now overexposed. The overexposed background will show up as a brightly lit area because the camera had to adjust for the foreground. This will actually reverse itself when it's dark out - meaning if the background and foreground are dark, the flash will expose the foreground, but the background will be black. Hopefully, that helps you understand lighting and exposure. Now, to fix this problem when shooting, you would need to consider several options - 1. SLR camera with aperture and f-stop settings as well as compensation controls. This will allow you to control every element of the exposure, but you still need to be aware of the lighting behind the "subject" to properly expose your shots. 2. backlighting compensation - common settings on both SLR and point and shoot cameras that makes auto lighting conversions for backlighting and other common lighting issues. Test whatever options are on your camera to see what works best for your specific problem. 3. Photoshop retouching - you may take one shot with your subject exposed properly and a second shot with the background then merge the images together. 4. using a tripod to shoot without using the flash - this may give you the closest exposure to exactly what you see when looking at your subject.

Grayblue Background on scans


A color scan will give real output as it is. If the background is grey, the output will also be grey. If you select 256 Color output, there may be small change in color, as compared to the original. If you select grey output, all colors will be converted to Grey. If these files are converted to PDF, it will be same, except in ODF format.

If you select B&W you can save the file in TIFF format. Unlike grey or color, each pixel can be either black or white only. To scan in black and white you must select right brightness. By doing os you can eliminate background (technically noise) and capture foreground(data)
