A nice article about wide angle lens photography - One (M7) General

Guys,
As many of you, I'd like to get the maximum out of the HTC One's camera, and I've found this article very helpful:
http://www.cambridgeincolour.com/tutorials/wide-angle-lenses.htm
It's the 101 of wide angle lens photography, I hope it would help you as well. Originally I wanted to post this to the 'share your photos...' thread but I think this way it will reach more people.
EDIT: yes, HTC One has a wide angle lens
Cheers!

And here is another, how to correct the distortion if you want. It's based on PS but shows the concept fairly enough. I think it's useful after people/portrait shooting and you want to undo the body part distortion (big head e.g).
The method itself seems pretty easy. I'll search for an android app to do it on the phone right after shooting but if you have some suggestions please share with us.

Camera Fix for the HD

I searched for a camera fix for the HD camera with no success. Does anyone know if there's going to be a fix in the near future? I'm sure that ya'll have the same problem that I do. Camera takes pictures that look old & rustic. Brownish tint to them & not very sharp for a 5 MP camera. I have adjusted all the settings for light & junk but nothing fixes it. As far as I'm concerned, it should take pictures IDENTICAL to a normal 5 MP digital camera. I can promise you that it's not doing that. Any help would be great, thanks in advance.

Why should it take pictures identical to a 5MP camera. The lens on the front is going to be vastly different, the sensor maybe 5MP, but what is the spacing on the sensor pixels? The closer together, the noisier the image. Colour balance will be down to the sensor too.
Regards
I'm not talking about the front camera. The normal camera on the back. I understand about the pixel thing, but it still shouldn't be so brownish, right? The pictures look like an old Polaroid picture. You know, the one's that spit the picture out as soon as you took it. Old, brown & nasty looking.
My pictures come out fine...
Hmmmmmmm...................... I'll just keep playing with it.

I'm not being flippant, but is it possible you might have a dirty lens?
Lol, that was the first thing I tried. Cleaned both sides of the back cover & cleaned the lens on the camera. Good idea, though.
The "5mp" doesn't really mean much, as stated earlier, if the sensor and lens are poor quality. As far as I know, HTC haven't released a phone with a reasonable quality camera, yet.
I bounce between different smart-phones (just coming back to WM now, after a year with S60). I can say that many of the S60 devices (in particular the Nokia N95, but also the N82 with Xenon flash) have very good cameras, being similar to low-end digital cameras in daylight. They lack optical zoom and tend to over-compress images, but have good quality lenses.
imho hd camera is excelent
pictures look old & rustic only if you make them inside house without using the artificial light setting, and this is also a general rule, not specific to HD.
Never seen a good phone camera yet, including the latest 8mpixel ones. They're all terrible.
Never
This camera will NEVER take pictures anywhere near what real cameras do. The photo sites are so tiny, they are smaller then the length of waive of light. Therefore noise, lack of dynamic width, etc. No patch will ever fix that. Sorry
open back cover , clean the lens , you will see a huge difference in quality

Not that I'm doubting you or anything but you do realize that the back cover only has a hole through to the lens?
You might try setting the brightness higher:
If you touch the small rectangle near the bottom right side of the screen (when holding landscape)
Then select the gear symbol, then select brightness from the menu and hit the "+" until it looks better that will remove most of the darkness.
The camera is a plain disappointment. In the time the camera autofocusses, I could have bought a Sony Ericsson C905's, create a good looking photo (with xenon flash) and upload it to imageshack.
If 'your object' makes the slightest move, your photo will be blurry . This is also the case when you attempt to make a photo of someone that isn't aware he or she has to be waiting for the autofocus lag. Head moves >>> blurry pic.
iPhone camera shots are way better quality, don't ask me why. Overall my Touch HD scores 8/10, where atleast 1 full point is taken up by the camera
and it's better don't speak about the very laggy video recording

Too many megapixels on a tiny sensor = major noise problem = blurring from denoise.
Even 2mpixels is too much for sensors this size, but people buy on marketing numbers of megapixels, not quality. You can just imagine the whining that would occur if the Touch HD came out with 1.3mpxiels, even though it would produce better pictures.

hehe, thats true.
mpixels dont count as much as the general public belives. the more mpix. the higher rezolution you can print the picture in. but for ordinary photos, 1.3 mpix would be enough, as long as the optics is good.
Personally, I rarely use a phone camera.
I use either my Olympus 720SW or Canon EOS.
​
the camera sucks **** compared to the n95 and the video recording is horrid. i know it's not meant to be as good as a dedicated camera but this is pretty bad given the price of the device.
i concur with mach03, move the camera a slight bit and eveyrthing gets blurred. one way i've semi gotten aorund this is to unlock the burst functiona nd take a sequence of pics and hope one or two coems out alright, not the most economic way to do it though...
i would ahve thought that maybe there's a way to tweak the camera to stop the blurring or even affect how much light is picked up by the lens which should also help with clarity

A silly idea, but seriously, did you check if maybe, just maybe, you left the "sepia" effect turned on???

HTC HD2 vs EOS 400D

just a small comparison between a professional camera and HD2's camera.What do you think? ( only cropped for same resolution, no color correction or anything)
HTC
EOS 400D
__________________________________________________________

HTC
EOS 400D
__________________________________________________________
Apart from the awfully wrong white correction, the HD2 isn't shooting the worst pics outthere, it seems.
With much light the camera is good enough for snapshots.
I think the EOS400D body needs to be sent back to Cannon and have the sensor cleaned and calibrated. And the lens needs to be cleaned.
the pics with the HD2 seem warmer on the flower and china doll. But the pics of the building and sign, are not that good. The 400D looks a lot better (except the depth of field, were the HD2 is sharper).
I have been playing with my camera a bit, and I cant get rid of the pink spot. I installed the update, and it made it better. But I still have a very noticable pink halo around 90% of my pics.
Detail on the HD2 is good once resized to 800pix wide or so, perfectly good for web use but not much more. And yes, the color balance is very often completely off, usually skewed to magenta...
+1 on your EOS being faulty, shot one is ok but shot 2 looks problematic

i m not a pro photographer. how do you understand that my eos is faulty or un-calibrated? is it that bad? can you help me a little?what should i do?
The EOS is all good to me, just a couple tiny dust spots visible on photo 3, but nothing else...
The colors can seem "wrong" next to the HD2's ones... but it's the HD2 being wrong
I cant see anything wrong with your eos tbh. The eos out does the hd2 in every picture except i think the last one. The difference I can barely notice. The first picture especially you can see how the eos brings out the purple in the center of the flower. It is crisp and has a more vibrant colour. Also the hd2 white on the flower is not very clear.
However we are talking a pro camera and a phone and I think for snap shots my hd2 is the best phone camera i have ever had. Especially in the dark in a pub etc as that flash is blinding!! If i wanna take landscapes i'll crack out the T90 or the fuji finepix.
EDIT After looking again at the last picture i think i prefer the hd2's. I can see what kilrah means about magenta as the blues in the hd2 version of the last image is slightly more vibrant. If you look at the sign on the building in the background ( the long thin one with the white writing) i think the blue is nicer than that of the eos. Thats not to say that the eos hasn't actually captured the correct colour but the hd2 colour is nicer.
I'm all for HD2 pictures, but let's be honest here, you should learn how to take better pictures with the 400D. In capable hands, there's no way you can compete a DSLR vs a puny smartphone with a static lens.
totally uneven comparison
I own both, and of course in "tailored" shots you can notice only what appear to be bare differences (Except the horrible pink staining effect which is visible everywhere even if background colours may tend to cover for it), yet in "daily life" shots you cannot actually make much out of it... also remember HD2 has a complete unalterable assembly, while much of the eos 400d power comes from the lens that you mount on it, and I am not really comfortable at all to compare my 18-200 OS sigma lens to the plastic on the HD2
If I need to shoot items I want to sell online, I always do it with my HD2, or even if I need to get quick shots of things where the main thing is to "get the idea", but I would never fathom to use the HD2 in a real shooting situation... like when I'm on vacation. I would simply lose every pleasure in shooting if I had to do it with a phone camera.

i didnt try to take good or stylish pictures.only took daily shots in a hurry, no manual settings or photoshop corrections.other way of course canon will shot much better pics. but i wanted to show that hd2 is also pretty good
Except photos 1 (flower) all pics from the HD2 are better than from Eos, more crispy-sharp, more depth, more details
... but this is only my personal sunbjective impression, I´m no prof. photographer though

you're missing the pink that stains everything in the center of the viewport
Also, if I had to define detail, I'd say hd2 shots, when zoomed in, show a very, very "washed out" aspect all over the area, while zooming in all the way shots by the 400d you can only see the normal amount of moiree
its an interesting comparison, maybe we should leave it there as it doesn't really mean anything beyond showing the HD2 pics arent too bad at all - which we already new
I have the hobby of photography.
All pictures from canon are a lot better than htc, and it's normal.
The canon sensor it A LOT bigger than a phone sensor.
You can notice that the canon pics are sharper, have a better exposure, a better white balance, a smoother out of focus, are less grainy. In some you have the impression that are crispier, but it's due to oversharpening (and if you like would be easy to obtain in pp on the canon shots)
About the depth of field, due to the smaller sensor of the htc (the smaller the sensor the deeper the depth of field), in most shots everything is in focus. But in photography this is a flaw. If, for example, I shot a portrait, I would prefer to have the face in focus, and all the rest out of focus.
On the other hand, on a reflex, you can choose the depth of field you prefer opening or closing the diaphragm
There are new sensor on the way and I'm sure that in future quality of our phones will be more and more similar to quality of point and shot cameras,
but will never reach the quality of reflex for the lack of BIG, HEAVY, good lenses.
Stop criticising the guys photographic skills with his EOS. All he was trying to do is compare an image from the HD2, with an image from a dedication digital camera, to show that the HD2 isn't all that bad. And people jump in expecting him to take photographs like Edward Weston. Give the man a break!
On topic: Nice comparison. Good to see that compared with a proper digital camera, the HD2 is still pretty good.
can you share your camera settings in hd2?
brightnes
iso
white balance
image properity
flicker adj.
thank you
HD2 has a bit of a magenta cast.
On the other hand, this shows how good the HD2 camera is.
HTC has come a long way from the 1Mb and 2Mb shooters that came with the BlueAngel and Prophet. HD2's photos now gets compared to that of an SLR.
Buy a decent camera, and also buy a decent PDA/smartphone. End of story.
There are so many *freakin* experts here.

Disable Wide Angle Shots

Ok we all have the same phone and the same lense front and back
This is specifically for the FRONT camera ... we all know the pictures are distorted ... its squashed from the center and appears long at the edges...
owing to the fact that it has a Wide Angle Lense
Which looks very bad during selfies
We cant change the lense as its a hardware part.
But is there an app .. or can we develop an app that corrects the distortion created by the wide lense and give us a straigt propotional shot ?
Im uploading a picture from another website showing the distortion of the lense. its not my own pic.
As im into Bodybuilding and also i take a lot of selfies ... my pictures look weird on my phone compared to my friends. My body looks normal on friends phone whereas it looks out of propotion on mine.
Lets discuss this ... cause im seriously considering a iPhone 6 over this phone now. but obv im falling back cause of budget issues.
its weird No one else hates the Distortion during selfies ?
a small bump up
I doubt there will be any way to fix it if it is the lens itself, if it's firmware, custom ROMs might be able to do it, Xposed Framework etc
No idea how though, I had noticed I looked like Bruce Forsyth a while back, but never took much notice as I don't use the front camera for much more than daft pics on whatsapp anyway
Hi all,
I am also interested about the resolution of this feature: there's no way to disable the wide angle? you have found a solution?
thanks in advance

Can you use the wide angle (back) camera to take selfies?

Hi all - it sounds like the front (selfie) camera does not take the best pics.
One of the uses I wanted for the G6 is to use the back camera (the wide angle one) to take selfies instead.
I won't be able to see the screen, but with the wide angle lens, I don't really need to do much framing I'm guessing.
The only thing that I'm concerned about is the lack of auto focus and if the wide angle camera can focus on subjects about 1 metre away from them.
Does anyone have a G6 who could comment / or post a sample pic of this? This is pretty much the dealbreaker for me to get this phone.
Cheers!
I'm interested in the same question! Would be great if anyone could comment on this, hence bumping this thread.
Yes. Front facing camera is not as good as it should be. Specially in low light situation...
This, and lack of LED notification light are the biggest flaw to me
Back cameras takes good selfies though. I don't have any problem with framing or autofocus. Does a good job with defocusing background and shaking effect is at minimum thanks to new image stabilizing system.
Hope this help you
Cheers
Someone here at xda calculated that all things between 35cm and infinity are in Focus for the wide angle camera.
I also made some tests and I think that he is not totaly wrong with his 35cm.
So taking selfies should be ok.

Rare 'fish-eye' effect on wide angle photos

Hello mates! I've had mi G6 for around 3 weeks and I love it. But the wide angle camera does some strange fish eye efect on the borders of it.
I uploaded one with the regular mode and another with the wide angle mode to make a comparison of both.
What do you suggest? Talk with the sellers?
Thx in advance.

That means that it is a normal behavior?
Yeah its normal
Haha yeah. That's how it works.
If you take a picture of a big panorama or something, you'll see it looks much better.
That's why the normal camera is used for up close normal photography.
Yeah.... wide angle lenses will have barrel distortion... that fish-eye effect... There is really not much you can do about it. Think about it, when it's taking that pic, the image it sees isn't 'flat', it's looking at a large arc, a 120-degree arc, then projecting what is essentially a curved image onto the flat sensor in the camera. Every wide angle camera lens will do this, and the wider the angle, the greater the distortion.
Now, your eye has a larger field of view, why don't we see the same distortion? Well, ignoring the fact that the human brain is one of the most powerful image processing engines in existence and will compensate for a LOT of junk, your eye's sensor, your retina, is also curved.
There are some tools you can use in photo editing applications that can reduce the distortion, and they stretch out the corners. Now, if you took that wide angle photo and then projected it on the inside of a sphere, you wouldn't see any distortion.
The main camera sensor is also distorted, but it's a much more narrow field of view, so the distortion is not nearly as prominent. But if you look at the margins of the pictures you take, you will still see some of that distortion.
