Help me to buy Camera under 100$

[fralexandr]

both those terms are used for the nokia pureview.
The pureview does not have a zoom lens. Its lens has 1 focal length (aka a prime lens).

the camera in the pureview uses the sensor to "zoom." This is typically called digital zoom, and usually results in poor quality upscaled images (i.e. taking someone's 80x80 pixel forum avatar and making it several times larger i.e. 800x800 pixel).
lossless digital zoom doesn't use interpolation/upscaling to make an image appear larger. It essentially crops an image from the ~40 MP sensor, in order to "zoom."

For example, most people have 1920x1080 displays. This is ~ 2 million pixels, or 2 MP. A camera picture has a higher resolution than this typical desktop display. With ~40 MP you would fill ~20 of these 1920x1080 screens.

-----
Say someone takes a picture of 9 squares in a 3x3 grid. At 1x zoom (~40 MP), you'd see all 9 squares. At 3x zoom (~5 MP) you'd see 1 square. It effectively cuts out the other 8 squares.

=====
The nokia defaults to ~5 MP images, since 40 MP images are large and use a lot of space. The 5 MP image at 1x combines several pixels to form a single pixel in the final picture. At ~3x zoom, pixels are mapped 1:1. This gives it the ability to "zoom" roughly 3x without needing to upscale the final image.

dual capture is the nokia camera's ability to save 2 images simultaneously: a ~40 MP and a 5 MP image. So, you're left with 1x 40 MP file, and 1x 5 MP file of the same image.

-----
So if someone took a picture of 9 squares, the end result would be 2 pictures. Both would be of the entire 9 squares, but the 40 MP file would have more resolution and the file would be larger. The 5 MP file would likely be used for uploading to the internet, and the 40 MP file could be used for a large wall print.

thanks man

bro what type of special of sensors nokia lumia,htc one mobile cameras have thats why they perform well in low light?

 

[fralexandr]

part of it has to do with sensor size (relative to number of pixels)
Larger sensors with fewer pixels, results in better low light performance.
At some point (based on sensor size, technology, and physics), increasing the number of pixels can decrease low light image quality.

the htc one uses a 4 MP, 1/3.2" sensor.
The sensor is the same size as most smart phone sensors, but it has fewer pixels.
Each pixel therefore has twice the surface area of those found in most other phones.
This in short, allows each pixel to capture more light.
http://www.htc.com/www/zoe/ultrapixel-sensor-size/

the lumia uses a 2/3" sensor, which is ~4-5x the size of normal smart phone sensor (1/3.2").

if viewing a 40 MP image at full size, you'll probably notice a lot more noise and poorer "per pixel" quality than most other cameras.
http://conversations.nokia.com/2013/07/11/nokia-lumia-1020-picture-gallery-zoom-in/
warning: website has links to ~13MB files.
at desktop resolutions (1920x1080) it won't be easy to notice.

-----
The other major factor is software based. Camera jpegs (and RAWs to a much lesser extent) are processed to remove some noise, provide some sharpening, and mitigate many other image quality problems. Newer cameras have better processing than older cameras. So if you compare images from similar cameras released in 2013 with ones from 2011, you're likely going to notice that 2013 has better low light performance (even given the same sensor).

This is also part of why photoshop exists. Computers have much more processing power than cameras, and even smart phones. Photoshop can be used to improve the appearance of low light pictures (assuming a high enough dynamic range such that the sensor doesn't cut out the information; completely WHITE or BLACK parts of the image)

Wise alexander bro,is it possible to take "toy effect" shots in digital camera? can u give me some photos where i can figure out the difference between 180* and 360 degree panoroma picss. i have read in some places in net where some folks says sony digital camera are not good.in one word crap.canon is value for money.whats is ur say? as noob,1st time camera user do i need features like 3d photo(i dont have any 3d monitor),60p video record option?is it possible to have slow motion in 30p video?does it depend of vid resolution like 720p or 1080p?some folks say sony digital camera records best video shoot.becuase their videos sound quality pure epic

 

[fralexandr]

There are a few cameras that include a toy effect filter. I know pentax includes it in some of their cameras.

http://www.gigapixel.com/
offers a few 360 degree pictures. the city of prague 1.6gp is 160 degrees.

even "bad" cameras are capable of taking good pictures (some photo editing might be required).

a lot of it has to do with technique, and composition.
anandtech likes to say in its product reviews that "there are no bad products, only bad prices" and this is pretty true. As long as the camera does what you need it to do, it's a good camera. There are a few cameras that are buggy and don't want to take pictures some times, but those aren't too common.

I've never used 3d photography, and don't have any 3d displays, so my only comment is if you really want it, get it. Not many people have displays capable of displaying 3d content.

it's possible to do "slow motion" on 30 fps
it would involve video editting.

video cameras that record at high frame rates only sort of depend on resolution. In the low budget range, most high frame rate capture will be done at low resolution, due to various limitations such as bandwidth. There are many that can do 720p @ 60fps, but anything faster will likely be even lower resolution.

Hey bro i have found samsung wb150f at about (used)70$ in amazon.what is ur say?i think its enough to full fill my needs. http://www.amazon.com/Leica-V-LUX-30...Leica+V-LUX+30 why this is so pricey??i dont find any clues so it can deserve so much$$$$$$$$$$

 

[fralexandr]

the samsung wb150f is good if you want the wireless features.

the v-lux 30 comes with adobe elements 9 and premiere 9, which is some rather pricey software (~$100-$200). A lot of what you're paying is for the brand name though (for people who want a leica, but don't want to spend for the more expensive versions). It's pretty similar to the panasonic zs/tz line.

What is TV link in digital camera?any video which how it use?
a comment about samsung wb150f which say that it takes blurr pic when moving.Does this happen because it does not have anti shaking feature?
Can u say any other model like samsung 800mv camera which have multiview?
i have seen this line in many cam reviews
"10fps burst shooting mode"what does it mean?If this line are not mention in review does it mean dont have burst mode?

What is the work purposes of lytro field camera?

 

[fralexandr]

TV Link

The blur is probably from autofocus not being able to keep up with a moving target, thus the picture is slightly out of focus.
The camera has optical stabilization.

adjustable LCDs aren't common on lower end cameras. It's usually found on more expensive models.
http://cameras.about.com/od/reviews/tp/best-swivel-lcd-cameras.htm

10fps burst shooting means it can shoot 10 frames/pictures per second. Most of the cheaper cameras can shoot burst at ~3fps.

-----
Lytro cameras take pictures with a more or less unlimited depth of field. It'd be nice if they let you display everything in focus, but that probably isn't implemented yet. It'd be great for macro pictures, and product pictures if they implement a firmware update for that. It should be a useful tool for action photography or fast moving subjects, if you don't need high resolution images.

They use a small sensor, and don't allow for long shutter times though, so low light will probably be problematic. Also, images are rather "low resolution" at 1080x1080.

The Lytro seems like it'd be a fun camera to play with. I've heard of the unlimited DOF/light field before, and I might've actually met the parents of someone that worked on it .
