Title: whasup with Cell phone cameras.
Post by: tp4tissue on Sun, 03 August 2014, 19:12:33: Like... IDK how expert photo-guys describe it.

It pulls the photo at an odd angle... and even if you get something "dead on" it's still slightly whharped...

Sup with that..?? is it some weird post process, or something with the lens(http://emoticoner.com/files/emoticons/onion-head/confused-onion-head-emoticon.gif?1292862495)

Post by: Hundrakia on Sun, 03 August 2014, 19:47:08: They don't have decent lenses on most of them, and definitely not adjustable lenses. I think there have been a few come out recently that do have more of a full-fledged optic solution on them, but I mean... let's face it. It's a handy tool for when you aren't at your camera, how advanced do we want these things to be? The cost alone of superior optics would drive cellphones out of the range of "that's cheap enough that the gf will let me purchase that! *cough nexus cough*"

Post by: Coreda on Mon, 04 August 2014, 06:57:10: OP needs pics as examples. Are you saying you notice fish-eye distortion in some lenses on phones? They are super tiny lenses after all.
Title: Re: whasup with Cell phone cameras.
Post by: Oobly on Mon, 04 August 2014, 09:02:40: It's quite common to have barrel or pincushion distortion with cheaper lenses: http://en.wikipedia.org/wiki/Distortion_%28optics%29

Some lenses will also have some chromatic aberration (rainbow-like effect, different colours focused different amounts). Lots of factors determine what type of distortion a lens will produce and how much and it's quite hard to get rid of all types of distortion, especially for a small lens with large depth of field like phone camera lenses.

Really good SLR lenses will correct for all three effects (barrel, pincushion and chromatic aberration) and will take very clear pictures.

What does a camera have to do with teens?
They only use the front camera for selfies. Or do I have the front and rear confused...?
Anyway, why not a nexus 5? Camera is great, just the image processing is ****ty. And that's the issue with new cameras on phones. Not all of them have great image processing. Parents are in their 40s, still take pictures of different things and send them to me and FaceBook lol.

My phone won't take a focused picture of keyboard while I have the leds on lol...

I would suppose it's due to my affinity towards less plausible, yet possible interpretations of all information.

Lots of use our cellphone camera to photograph new keyboards.

Remember: they say "the best camera you own is the one you have with you". I always have my phone with me, so I always have the camera.

Plus it's really easy to use it to remember things for you. Like who borrowed what. When they borrow it, take a photo of them holding the item and put it in a folder. Then you know who borrowed what and when they got it from you.

A well-executed cellphone picture is normally more than sufficient to get the details on a keyboard or switch that may be uncommon or rare. As such they are wonderful for documenting things. Keep in mind: such a use-case is to focus much more on clarity to make sure the details are shown than aesthetics.

That teen age thing was just simplified stereotype for sake of provoking. Of course people use their cameras on their phones. Camera phone has became the standard and people are used to it. There is tons of implementations linked to them.
In some countries it's even the standard that mobile phone cameras are the only cameras people have, if they even have those.

What I'm actually trying to say that nonetheless there are people who could cope without having that camera. For example if every manufacturer had one smart phone model without camera and that would transfer to the price tag, I think some people would buy them. Those wouldn't be top sellers but I think they would sell enough. I use my mobile phone camera probably once in a month and could live without those pics. For the sake of irony maybe there would finally be something worth taking pictures when I didn't have that camera with me all the time (and I wouldn't mind that)...

I already have Nexus 4 and it takes wonderfully ****ty pics.

For next provocation I tell you more about how behind of time I am in the context of mobile phones. I've usually changed my phone in every two years. That two years mark is closing for my Nexus 4 but I can't find any reason to change. New phones have little bigger and more precise screens but nothing worth spending. Hardware is little better but my current hardware hasn't really been a bottle neck for any every day software. Development of battery technology in consumer electronics has been behind for some time already. 4G is only reason I can think of but finnish operators are sooooo behind on that. 4G spread is still too low and the prices are way up. I need to wait until that has been fixed.

Only innovation on mobile phone market has been what OnePlus did. The innovation that you can sell the same **** that everyone else is selling but sell it cheaper by saving on marketing costs. Unfortunately that won't make that big change because the most of the consumers will just buy the phone which local seller markets for them or which has had good coverage.

I've probably gone enough off topic...

Are you talking about barrel distortion?

Lets say you take a portrait of someone (straight forward)..

but no matter what you do.. his face/body does not appear symmetrical in the photo, whereas if you're looking straight at the subject, it's symmetrical..

For example, I was trying to take a picture of my motherboard.. I couldn't get it dead centered for the life of me... It was always pulling the corner to one side.

Post by: C5Allroad on Tue, 05 August 2014, 00:49:40: Hardware is kind of irrelevant nowadays. It's about software. And stock android just works and is smooth.

Google needs to work with image processing. Not too sure about the sensor in the N4, but the N5 the sensor is made my Sony. So theoretically it should take good pictures. Like you said. Wonderfully ****ty lol.
