My HD2 Supermacro shots :D

I took an idea out of Lifehacker and ripped out the lens from a DVD player to make a ghetto macro lens. I taped this to my HD2 and took a couple of these shots. They were grains of rice about 1mm in diameter. (Rice grains can come in huge sizes too, but these were tiny )
Photos were then touched up in Resco Photo Manager and sharpened a little in Pocket Artist. I used Photoshop on my laptop to resize the shots to exactly 604 pixels on the longest end. This ensures maximum sharpness when uploaded to Facebook... however, that step was not entirely necessary of course and I could have just sent it straight from my phone to FB or Flicker using Resco Photo Manager 7.03 (an AWESOME program!)
DOF was tiny and there was no additional lighting used apart from the camera's LED. It wasn't easy. The lens was almost touching the rice. In post processing, I had to reduce gamma and brightness and boost contrast. However, in keeping with the main goal of the project, I did all such modifications to the photo on the HD2 itself
What do you think?
Here is a link to that Lifehacker site;

Thats actually fairly impressive! Is the colour balance your choosing, or a side-effect of the HD2s camera in such proximity?
All we need now is a way to turn this macro lens into a flip-on flip-off attachment to a phone

When I say "fairly", I mean "very", btw

They look pretty damn impressive!
Can you get a close-up of your fingertip? It's always a good judge of a lens as to how clearly they can get a fingerprint.

I will try that later tonight I did have a go yesterday but didn't keep the shot... The magnification was so great though I think I could only have 5 -6 lines of my fingerprint show up....

That was the HD2... after adjusting gamma and contrast... before, there was a blueish glow to it. The rice was sitting on my black HD2 case which came with the phone

Ah I see. Still, I will have to dig out an old PC and see if I can get the lens from it and do this myself. I think with a few people working on it and sharing settings/ideas we can get a good thing going!

That's pretty damn trick. I like it!!

Simply awesome

Weird camera focus problem

I've tried to search around for people reporting the same issue on the nexus 4 and I haven't found anything. So I may be alone on this one...
Basically every single picture was a weird blurry area on the very left side of the picture (or upper side if on portrait mode).
There's no smudge or anything, I've triple-checked and cleaned.
I've only had it for a couple of days. The only few pictures in which I can't notice this problem is because there's a wall, or sky, on the left.
Here's a picture taken with my phone:

and here is a picture taken with ANOTHER nexus 4
I chose that grid because it becomes pretty evident.
Thoughts? Is this an autofocus problem or is the lens screwed up and I should get a replacement?

i think i might have the same problem... anyone any idea???

Camera lens misaligned maybe? In normal photography with say a lens being much larger than that in the camera, a blurry edge would usually be evidence of a misalignment (ie: the element being tilted from the plane of focus, or off centered from the 'sweet center'). But due to the extremely tiny sensor on most camera phones, something like a minor tilt or such is usually never noticed because they already have a pretty large depth of field in the focusing.
So if it's obviously not something like a smudge or scratch near the lens element, and it's always on the left side, I would probably say the actual glass element sitting in front of the sensor may be tilted (it could be like half a milimeter off and that's all it would take).
To seeing if you can do something even closer , macro-like, as tilted lens are even more obvious once the DOF (depth of field) because more narrow, especially since adding any distance between the phone which already uses a very wide lens and the subject will just increase the depth of field. (low aperture, close distance to subject = decreased depth of field).
PS: Whenever I did focus and alignment testing in the camera shop, we always used a tripod with a bubble level and a actual focusing grid on the wall, you can see examples of those grids over at dpreview on just bout any camera review.

There is not much of a lens on this camera. I think expecting corners to be as sharp as the center is unrealistic.

Two Cameras are Better than One: How the Dual-Camera Setup on the Honor 8 Works

How the Dual-Camera Setup on the Honor 8 Really Works​Dual lens cameras seem to be the way of the future. We are seeing many smartphone companies make the switch to the two-lens setup. In this thread, I'll go over exactly how the cameras in the Honor 8 really work and why it's better than a traditional single-lens camera.
What do the Sensors do?

RGB Sensor
The RGB sensor is designed to capture rich true-to-life colors.
Monochrome Sensor
The Monochrome sensor is dedicated to giving your photos increased sharpness and capturing more light.
Having dedicated lenses for different sensors allows for much higher quality photos. Here are some photos taken with the Honor 8, to show off the color and detail quality of this camera.
Hybrid Auto-Focus​When reading about the hybrid focus, the Honor website states
The hybrid auto-focus enables laser focus for short range, precise depth focus for long range, and contrast focus — each working together to help you take better pictures in complex lighting conditions day and night.

I found this being a nice benefit in "complex lighting" situations. In photos with very dark and light spots, typically a camera will have to accommodate one or the other, leaving one part of the photo lacking detail. Here are some photos of situations with bright lights and dark shadows. Notice how everything is even and very detailed.
Dual ISP​The image signal processor is in charge of the autofocus, exposure and white balance. The built-in dual ISP improves the speed of the focus and process time when you're taking photos. This makes snapping high quality photos quick and easy, by removing time spent focusing your shot.
In conclusion, two lenses are definitely better than one and the Honor 8 does this very well.

Galaxy S5 Camera Quality Deteriorating

Hey all!
So my sister has had get S5 for a while now, she likes the phone immensely. However she's pointed out an issue which I haven't come accross before. Over the last year and a bit, her camera quality has gotten awful. When she first got the phone, it was taking good quality, in focus pictures. Now, although they aren't blurry, they're somewhat not focused and grainy - as if she was taking a photo with the S1 for example.
See below photos for reference. If it's the lens that's dirty - I'll simply replace it. Not sure if it's firmware or not. I also found it incredibly difficult to focus whilst takin the first photo.
Thanks!

My camera covering glass is differrent from that of yours

you have already the answer in your last picture , the glass of the camera is full of dust thats the reason look for a tutorial on how to clean it or take it to an expert to do it for you

Dark spot on camera

I have had this phone for three months, and have taken care of the phone very carefully. Now this random dark spot appears on the none wide angle camera in photos and videos. I haven't done anything that I can think of that would cause this other than accepting this big update on my phone a week or so ago. Anyone know if it's defective, or something else like software? This is the Canadian Rogers LG G6 version. I love this phone and just got it no long ago... I have no idea what I should do, because it ruins certain videos or pictures now. Here's a video to show what I mean, https://youtu.be/31gP0E3hmwo

Weird - did you take an extended video of the sun? Also, I'm sure you already have cleaned the camera glass many times, but when you clean it, did you look closely for anything out of the ordinary, maybe trapped between the outer glass and the inner lens?

No, I always avoid getting the sun into my camera for the fear burning the lens. Only thing I can think of my lens getting a lot of light is when taking extreme zoom in pictures of leaves that were in the sun one of those zoom in clip on lenses. Though the camera was facing down on leaves and not towards the sun.

I will have to look at the lens again when cleaning, because I didn't notice anything before.

I just did another test while looking for dust on the lens with a soft flashlight and this spot turned into something else. So confused, because I don't see anything when I look at it. Here I recorded it https://youtu.be/ujwJEvfcQ44

I think there is something between the lens and the sensor. I would send it to repair.

I've the same problem few month ago, I just shake the phone because I thought it was a dust and the dark spot disappeared

I'll trying shaking it before sending it to repair, hopefully shaking works, thanks for the ideas.
