14 mp camera image quality?

Question

i have fujifilm s3300 . 14 megapixel, 26x optical zoom, 6400 iso, focal length
f=4.3mm - 111.8mm, equivalent to 24 - 624mm on a 35 mm camera
full-aperture
F3.1(Wide) - F5.9 (Telephoto)

http://www.fujifilm.in/products/consumer…


now thing is that with these feature my camera should be able to click a quality pictures.... but it is giving a low quality picture of 72 dpi... where as my nikon 7 mp camera is able to click high quality 300 dpi picture
(my fujifilm box say made in china)

other detail of pics are
dimension 2048 x 1536
width 2048 pixel
height 1536
horizontal resolution 72 dpi
vertical resolution 72 dpi
bit depth 24
resolution 2
color rexperimentation sRGB
f-stop f/4.5
exposure time 1/4sec
iso speed ISO-400
exposure bias 0step
focal 10mm
max aperture 3.,26
metering mode pattern
brightness 0.49
exposure program portrait mode
sharpness normal
white balance auto
exif version 0230


and its optical zoom is not giving good quality pic also the picture click looks like some1 have crop a part of the pic to attain that pic doesnt 26 optical zoom meam that i get picture same quality like we get a picture when we dont use zoom otherwise we could simply crop a pic, what is the use of spending money for optical zoom ..........


where as my nikon 7 mp camera hade 4x optical zoom

i remeber when i clicked my brother pic using nikon camera it gave a high quality picture.. we could also crop the girl standing about 20 foot away from myn brother and that (cropped pic) was also high quality, we have enlarge copy of that pic (and believe me its not pixelated, infact it appear that i was just standing inderont of her and took her pic and she is posing for the pic only,,,,,,) where as I cant even get the clear enlarge copy of pic clicked by fujifilm s3300.. it is not giving a dense picture..

Answer 1

..



DPI is a PRINTING TERM, It has nothing to do with DIGITAL IMAGES. Printing is what you do on photo paper or well other media and as you print the printer software will turn it into a 300 dpi image usually depending on the settings you use.



So until you print there is no need to change the DPI. If you look at a picture on the screen for editing 72dpi or 300dpi doesn't matter. It is only once you print that the DPI gets into play and the software you use, the printer drives and so on will suggest something like 300dpi and it will be printed at such.



The actual image quality, the quality of the Contrast, Sharpness, Noise Performance depend on the lens and the size of the sensor [and how many pixels they stuffed on it] Your camera is not terrible but definitely combines a small sensor with allot of pixels with a long lens. This means that yes the quality is limited. I wouldn't say bad because you get good result for the price you paid but DSLR quality it can't hit.



That the pixel quality might be less then with your 7 Mpixel has to do with sensor size. Those 7Mpixels are on the same area as your new 14Mpixels. This means every pixels is 1,4 times at small [lenght wise]. This means more noise and lower dynamic range.



Welcome to the hell of the Megapixel Myth. I saw your picture and well yeah having to use ISO 800 to get that picture well that is the price you pay for putting so many pixels on such a small sensor.



That and the lens well it has allot of zoom but this also means it has allot of possible weaknesses. How more zoom how more can go wrong. And yeah above a certain level of zoom it probably gets a bit soft, loses sharpness.



You bought marketing wise a powerful camera that just tries to much quality wise. Sorry but we can't change the physics. If you buy a Superzoom you get allot for cheap but sacrifices have been made.



The best camera has HUGE sensor and HUGE pixels combined with a piece of glass that precisely 1x zoom. Your legs are your zoom! Even use DSLR owners are not getting that. The best DSLR's are Medium Format cameras they are expensive like a sport car and before you are done with enough lenses and tools it might just makes it 2 sport cars. Yeah kinda out of reach.



Marketing makes it so easy "We have more megapixels" so what if they are worse of quality then I rather not! "This one has 30x zoom" on DSLR's our zoom ranges are usually around 3x. For a reason that way our glass can retain most of its sharpness and contrast. But still it remains the best lenses do no zoom.



Sorry again but this is how it goes enjoy the camera you have don't print to big and there you go. If you print nothing bigger then Letter size then any noise caused by the small sensor should fall away against the pixel binning effect the printing does. Aka you have more pixels then your printer is going to print anyway at 300dpi so some of the noisy pixels can be thrown out.



Oh by the way 2000x1500 is 3Mpixel.. why the hell are you shooting on LOW IMAGE SIZE mode. Seriously?



If you find it odd that there are not many pixels well maybe you should shoot in full image size mode. High Quality! If you set your camera wrong you shoot ****.

Answer 2

Make sure you have the camera set for the highest resolution and size. Most cameras have different settings - say you are wanting to post photos on the web vs. making enlargements; that would dictate different image quality.



One thing many people don't realize that with something like a 26x zoom, the one thing that suffers is image quality - especially at the telephoto lens. Fact is, there is no perfect lens, and the larger zoom range, the worse. It's all compromise, and the more range, the more compromise.



Just like the fallacy of more MegaPixels is better, longer zoom lenses are more marketing strategy than engineering.



Although there are a few lenses in the 10x~12x range, most DSLRs have lenses in the 1.5x to 3x lenses, precisely because of the low quality of the super zooms.



I have several cameras, one being a Fuji S2950 with a 18x zoom that I leave in my car. It is all but unusable at the 500mm telephoto end due to lens softness. So you are going to have to take a few photos at different focal lengths and figure out where the lens works and where it doesn't and go from there.

Answer 3

Sony is a good reliable brand, but 14 MP is way more than you 'll need. It really eats up the memory, but you can choose a lower resolution to avoid that. A 7 MP will give you a good 8X10 print which is usually more than most ppl want. The price reflects features and modes. That model doesn't have an optical VF for one thing. Better a name brand like Sony, Canon, or Nikon than an off brand like Samsung or Polaroid

Answer 4

Based on the pixel dimensions you have set your camera to save the photos in a low resolution version.



Just to clear up a misconception: The 72dpi are not a sign of low quality in any way. They are merely a piece of information for a printer saying in which size to print the photo - but that can be changed at will in post processing. That your camera is set to 72dpi as a default has NOTHING to do with image quality..
