People on social media are constantly looking to click better pictures to upload to their growing online-photo collections. Buying an expensive smart phone may not be enough to up your game in photography, but a little research on camera specifications and nomenclature will go a long way in helping you select that perfect smart phone for your next photographic expedition.
Camera Glossary
Sensor: A sensor captures light and converts what you see into an image. It determines image size, resolution, low-light performance, depth-of-field, dynamic range and basically how good your photos look.

The quality of the image depends on the size of sensor, the number of pixels on it and the size of those pixels. For example: Samsung’s ISOCELL image sensor technology promises increased light sensitivity and higher colour fidelity in smartphones even in poor lighting conditions.
Aperture: The aperture (sometimes called focal ratio) of a camera is the ratio of the lens' focal length to the diameter of the entrance pupil. It is a measure of lens speed, and provides the thrust to produce photos with better sharpness and clarity. The higher the focal ratio and the smaller the opening in the lens, the greater the depth of field and sharper the background of the photograph.
PDAF: Phase Detection Autofocus (PDAF) is currently the fastest method of focusing. It uses two sensor points to detect the phase difference in the light path and find the exact distance. It moves the lens to the correct focus point so that the camera produces high quality images. A few smartphones also use VCM ball bearing and closed loop technology in PDAF, which lets the user click a picture in less than 0.09th of a second.
Megapixel: This is a unit for measuring image resolution. The more the pixels in a picture, the more detailed the picture becomes. To put it simply, a single megapixel amounts to one million pixels in an image and is an indication of the camera's image quality or resolution. So photographs taken by a camera with higher megapixels will result in higher resolution images.
Resolution: This refers to the number of pixels in a camera sensor. A higher resolution means more pixels and more pixels provide the ability to display more visual information (resulting in greater clarity and more detail).
Autofocus: The Auto-Focus feature provides a camera with the ability to automatically focus on a subject correctly without the need of manual intervention from the user. This feature allows improved zoom shots and closer macro shots.
So don’t be camera shy, go ahead and research these terms so you have the right smart phone to click that award winning photo!

4. Big visual angle
By PVA（Patterned Vertical Alignment）visual angle can be dual 180digree in vertial and horizontal.
5. With Better reliability
The design for LCD TV and LCD Monitor cannt support use in day and night, and LCD DID is used to Surveillance center and Exhibition Center with use in7x24 hours.
6. Pure Plane Display
LCD is the representative of Plane Display Equipment, truly pure plane monitor, wihout curvature picture and anamorphic distortion.
7. Design for super thin
DID products is advantage in super thin and light weight while super display area. DID is designed in excellent narrow board that is less than 1cm , so that there is no effect on the piture .
8. Euqal Bright , no flicking for picture
Every pixel of LCD Display Equipment keeps the color and bright after got the siginal ; But CRT is flashing new pixel. That is reason that LCD is with equal bright and no flicking effect for picture.
9. DID in 120HZ flash ratia.
The Display technique of LCD DID in 120HZ supply one solution on Smear and blur, and boost up the definition and contrast ratia in order to make picture more limpidity . It is good for our eyes.

Why HDR
------------
Real life scenes often have a wide range of light intensity, which cannot be captured by a camera. In a photo of such a scene the bright areas look washed out and everything in shadows is pictured as a black spot with no details. The HDR technique allows you to capture details in bright and dark areas and have them merged in a single photo.
HDR photography is widely adopted by professional photographers. Wouldn't it be nice to have an HDR in mobile phones?
The problem is that HDR requires taking several differently exposed images in series, which must be precisely aligned and then fused. In order to be usable for real life scenes, the HDR feature should include moving object detection and hand shake compensation to avoid or minimize the ghosting in the final image. That requires a lot of computational resources and makes a challenge even for professional desktop HDR software.
Almalence has brought its expertise in professional HDR software to mobile phones. Our HDR fusion algorithms compensate hand shaking and detect moving objects in the scene, suppressing ghosting artifacts. At the same time, the algorithms are quick enough to provide comfortable processing time on mobile devices.

Hi all this thread is about the front camera of Honor View 20.
We have been seeing various articles and reviews about 48MP back camera but there isn't much info regarding front camera.

After various leaks Honor View 20 got released in China. It is yet to be released world wide which is going to take place on January 22nd.
From the renders and reviews and various hands-on we got to know that Front camera is a 25MP camera with AI feature and f/2.0 aperture.
On paper specs look like one of the cameras from the recent mobiles.But its placement makes it different from other cameras.
Honor considers Hole-punch Screen Technology is the replacement for the Notches in order to have high STB ratio and for utilizing maximum screen real-estate and is one of the key selling point for Honor View20.
The Honor View20 has a big “All-View” display with the in-display hole, which is only 4.5mm wide. According to available data it is to be considered as the smallest hole when compared with other models which have similar camera placement.
From the available data it is to be noted that it is assembled with 0.1mm precision with 5-axis Ring Dispensing.
You might have heard that due to camera punching through each layer of the display it has a greater chance of light leaking through. This design could result in poor quality selfies. There’s also the problem of the display’s durability being compromised by the design.This could cause a display be be easily broken.
But Honor mentions that it has overcome all the issues through its special technique called pixel transition technology, which controls the flow of liquid crystals, enabling light to go through and reach the camera along the liquid-crystal layer .
I think it is better than the Notches and is nice to look .
Do come and share your opinion regarding this.
I like the placement of the camera. I did not find it very noticeable when holding the View 20. Plus its location in the upper left corner means it will be under my left thumb when gaming and the phone is held in landscape orientation. I did not get a chance to try watching anything on the View 20, but I do not believe its location will be a distraction for me personally.
Camera Tip and Tricks for the Honor View20
The Honor View20 has one of the best Sony camera sensors available for phones right now. The 48MP back facing camera is a real game changers. Here are a few different tricks to try out with your new camera.
1. Aperture Mode
The trick to creating a great wide aperture effect is having a phone with a great camera and software that can accurately differentiate background object from foreground objects. The AI NPU chipset makes all the difference in this area. The phone's ability to identify different objects and and use the dual-cameras to recognize depth, means the Honor View20 can create extremely effective aperture mode effects. Get creative with this mode and see what kind of shots your can get.

2. Portrait
Portrait mode is done extremely well on this phone. If it's your first time using portrait mode, know that it's basically your phone detecting the outline of your head/body and blurring the background. The quality of this popular effect comes down to your phone being able to accurately trace your face and remove it from the backdrop.
The Honor View20's large 25MP selfie camera lets you take really detailed selfies that look amazing. Try out the portrait mode with your selfie camera and you're going to be really impressed with the results.
3. AI Mode
AI mode was one of the main features advertised in this phone. Toggle it on and try it out. It can really bring out the color in some of your shots. If you don't like the way the effect looks, you can toggle it off afterwards in your galley. I have this feature toggled on at all times, since there's really no reason not to. Your original image is always preserved without the AI, so you can get rid of it later on.
Keep in mind that AI mode is not available when shooting in full 48MP mode.
4. Video Format (H.265) (H.264)
You can choose the format in which your videos are encoded. You have the option of H.265 or H.264. The H.265 option will give you a more compressed video resulting in a smaller file size. The H.264 option is a less compressed format and will have slightly higher quality video.
Go to Video > Settings > Video Size > Format. to access this option.
5. Edit Your Camera Menu
With all the different camera modes built into the default camera app, it's nice to be able to customize which modes your have quick access to.
From your camera app, go to More > Edit then you can rearrange all of your different camera modes.
Also, if you're wanting to test out the 48MP camera feature, make sure you change your resolution in the photo settings. By default, your camera will shoot at 12MP. When shooting at 48MP, it's best to use a tripod to keep your camera as still as possible. After you are done shooting, your camera ill revert back to the 12MP default option.
I recently received the new HONOR 9A and wanted to share some of the photos I've been able to take with it.
The Main camera is 13MP with a 5MP ultra-wide camera so it's a little difficult to compare with say the HONOR 20 or 9x Pro but that doesn't mean that it doesn't capture decent photos. All the photos in this post are unedited with the exception of some cropping which doesn't interfere with or alter the photo quality!!

So to start you can see above the 9A Camera performs well taking a variety of photos. Views, Pets and Flowers all captured beautifully in bright and crisp detail. I was pleasantly surprised at the clarity of some of the Snaps I've managed to get so far.
I found outdoors in the sun was the place to be with this camera. The blue sky and light reflection in the lake is a perfect example of the colour and detail it can capture. It doesn't always fair so well dealing with lower lit conditions but there are plenty of more expensive phone cameras out there that the same can be said for
I see this phone and camera as ideal for someone looking to snap a few memories on family walks and days out or a youngster just starting their tech adventure and taking photos of all the random everyday objects that I now regularly find in my daughters gallery.
Simple and no nonsense is how I would best describe the HONOR 9A camera. There are few extra features although there is a cool Panorama mode and a whole range of editing tools in the gallery including the brilliant colour "Splash" tool. There is actually one edited photo in this post. Below is an untouched and a lightly edited version of the same herb garden done using the 9As editing tools. Brightness and Shadows can easily be tweaked and adjusted if you feel you need a little more warmth and colour to a photo
Finally I wanted to show you a comparison between the Main 13MP Camera and the Ultra wide 5MP Camera. As you can see below with both shots taken from the exact same spot, there is quite a difference in the width.
Again I was hugely impressed with the quality of both shots and you have to look quite hard to spot any real difference in photo detail. Overall I am very impressed with what I've seen from the HONOR 9A camera so far. It does everything you need for an "on the go" phone camera and will be absolutely perfect for a lot of people. For a phone that is currently available at the ridiculous price of £129.99 the camera was never expected to compete with the more expensive models but you are definitely getting more than what you pay for. Speaking of which I saw this little bargain earlier..
I am looking forward to testing out the camera further by taking a much wider range of shots and also comparing the photos with other HONOR Cameras. So what do you think of the HONOR 9A? For me it is definitely a bargain and comes with a camera that has far exceeded my expectations. Cheers for Reading!!
