The camera on our Note 4 has a fixed aperture of f/2.2, which is a lot compared to standard cameras.
Those familiar with Depth of Field (DOF) will know that such a small aperture gives a very shallow Depth of Field, and it is impossible to take close-up shots of small objects and have the entire scene in focus.
My question is this: how can I increase the Depth of Field of close-up photos taken with the Note 4 ?
Try Camera FV-5
The note 4 doesn't have a variable aperture lens...
Well you already said that the aperture is fixed. Since aperture and sensor size is fixed you cant change the depth of field.
However you can do it artificially with one of Note 4's Selective Focus mode. Since you want to increase the depth of field of close up objects, select "pan focus" when choosing the subject of focus . However it does not work all the time, especially when your "near" object is too close to the camera
Another way is to simply move your phone away from the subject until your background is in focus. then you crop.
To be honest . The DOF of note 4 is not shallow. It's just that the macro performance of note 4 is quite good and you are allowed to get close to your subject while staying in focus.

The camera of the mini seems to have trouble to focus. I am getting sharp pictures at close distances (up to 2 meters or so), but the higher the distance to the object, the less focused the pictures are. Tried refocussing and focussing using the touch-focus function - still no good results. Pretty disappointing.
Anybody having the same experience?
Same issue, but i believe it is affected by spot metering. The spot metering governs the shutter speed and aperture settings. So if the spot is pointed on a dark patch on the picture the camera will either decrease the shutter speed to allow the picture to be brighter. I suggest if we are able to change the spot metering to centre or average as per the old phone, we might benefit from a sharper picture.
that is just my 2 cents. I am in London this weekend just trying to test use the HD mini camera, I do use a Leica so i have a few cents on picture taking.
I noticed: the lower the resolution, the better the focus...
Here's the deal, I'm curious to know what ...peoples best found camera settings/ tweaks for the best clarity on ranging from "moderate distance , to up close shots ".
I had the HTC one initially and fell for the camera day one, then ended up getting a s4 I had for a week ..and I really enjoyed the extreme clarity as far as detailed focus was concerned on up close pics when I say upclose I mean anything within 10 inches of the camera focused any blurr right out into clarity . While the s4 seemed to focus Into detail ,the HTC one seems to struggle just a bit.
All in all I returned to the htc one as I like it more ... for many other reasons .
So who has some specific One cam settings to share ,that have been found to be perfect thru trial and error.

There are no "perfect" settings. Everybody sees different things in a photo and from a previous thread I saw, variants were very different on the setup of the camera. The way I see it is this, play with the settings and settle on what looks best to you. forget what anybody else suggests because it's only what you think that matters ..... Personally I have mine setup as it came, default on everything and I'm more than happy with the quality of the pictures.
- The HTC One has a large sensor
- Large sensors produce "shallow depth of field"

Regardless of sensor size, depth of field is dictated by the aperture and not sensor size. Bokeh is more apparent with a wider aperture (faster). The HTC One sensor is exactly the same size as every other camera sensor in high end Android devices.
Personally for me I use -1 Sharpness and +1 Contrast.
Ok I'll agree with you I guess- it's a large "opening" where the light goes in. Large aperture. Fine.
A large aperture does cause shallower depth of field.
I guess that article just says there's multiple things that go into determining how deep your focus will be and *all other things being equal* larger sensor size changes the geometry in a way that generally decreases depth of field.
To spell this out for everyone one more time: In an image portraying many objects of widely varying distances from the camera, it helps draw attention to the objects that the camera locked focus on by increasing the likelihood that other objects will be out of focus. This is often desirable. The OP of this thread apparently was in a situation where he did not find it desirable, but that is not necessarily a *defect* of the camera, just a design decision.
I have a note 3 sm n900.
But in my camera if the turn image smart stabilisation off the photos sre taken are very fast but they start cracking if i zoom in.. if i take a pic of a book or something the words arent very clear,i even tried keeping my hands very steady while taking the photos.
On the other hand enbablimg smart stabilisation, camera takes around one second to take a photo and the photos arr very clear.
This shouldnt be happening, right?
Whats the point of having smart stabilisation off if the photos look like taken from a 2MP shooter.
Please help.
Please reply.
I have been hurt by the community as my last problems didnt even get a reply.

Are you aware of how camera sensors work?
Smart stabilization is meant to offset the use of higher ISOs/lower shutter speeds so that your pictures turn out less noisy. Given that the Note 3's max aperture is f/2.2, let's make an example.
In the daylight, your ISO can drop and thus picture quality can improve (this is very barebones, but it's for conceptual purpose). In essence, higher ISO = more noise, especially the smaller the sensor size. You can visibly see that the Note 3 has a very small sensor. In fact, even on APS-C cameras, noise performances starts to suck around ISO 3200~6400. ISO is meant to make each pixel brighter (or something to that effect), and the smaller those pixels are, the more noise you'll generate (again, not exactly, but that's the gist of what you're experiencing). So, with 13 megapixels fit onto the small sensor, you're likely going to start seeing noise at like, ISO800 (this is a random guess, but it's probably true).
Anyways, so during the daytime, there is a lot of available light, so the ISO can be reduced and exposure can be adjusted using shutter speed (assuming aperture stays the same). This improves picture quality as lower ISOs generally equate to less noise. However, as you get later into the night, less available light means that one of two things has to happen. Either your shutter speed gets slower to let in more light, or your ISO cranks up to become more sensitive to the available light (and thus more noise). Usually a combination of the two occur to get a trade off between quality and shutter speed.
A quick browse on google gave me, 1/15, f2.2, ISO 1000, as EXIF data from an iPhone 5s taking a picture at night. As you can see, the ISO is pretty high for the small sensor, and the shutter speed is quite low. As a rule of thumb, you generally want at least an equivalent shutter speed to the focal length, but given the crop factor of this lens, I have no idea what that'd actually be. But 1/15th is very, very hard to hold without some form of IS/OS, even on full-frame cameras. What you're experiencing is this effect. The low shutter speed to let in more light means that even if you breath and shift the camera 1cm, you'll get blur. It's not out of focus, but the subjects weren't in the same place because you moved, causing them to be rendered in shift. The noise is the result of the ISO being too high; the pixel sensitivity isn't that great, and so you're getting all kinds of weird colours that the phone is trying to represent without definitive data. Again, we're assuming that the aperture stays wide open under these conditions to let in the most light.
I hope you got the answer you were looking for. Basically, what you want is pretty hard to do, even with a full-framed DSLR (although it's becoming less true with recent image processing). You can't really turn of IS/OS and expect the pictures to be great. There's a lot of other things that are taken into account behind the scenes that are usually beyond your control on your phone. Smart stabilization using image processing algorithms to help mitigate the impact of higher ISOs and lower shutter speeds by post-processing the images you take on the fly. Such is the cause of the delay.
What version you're running , do you try to use any third-party camera app results may vary , did you increase exposure value, try to reser all camera setting to default

Got it sorted out. In not so bright conditions the pictures start breaking and by turning on smart stabilisation it gets fixed. Credit goes to the last persom who explained. Best explanation ever. Hats off to u

After having the Honor 8 for a while, I just started doing more photos and videos.
One problem I have seen with video and photo is focusing on distant objects, either moving or stationary.
It tends to be blurry and focuses wrong, even when touching the screen on the item I want it to focus on.
A photo issue I have noticed, (mostly this christmas) is when someone is opening a gift Most of the image taken is fine, but then have a
blurry hand or someone moving too fast. Problem is it really isnt that fast. I can probably do pro mode and decrease shutter but then may get under exposure issues.
Any tips I can do to avoid these issues or any tips on photo taking will be helpful.
Thank you.
The problem there's no OIS (optical image stabilization), that's why objects get blurred when moving.
I'm no expert but I've found that the more you can steady this cam the better off you'll be. Anchoring your hand on a solid surface helps tremendously and I've also had some luck using burst mode, then you can at least pick the one with the least blur.

FYI, OIS won't help you with taking pictures of moving objects. It only helps steady the camera, which only helps if you're not holding the camera steady enough for the shutter speed.
OIS is a must for a high-end phone, I hate to stabilize every time I take a photo, even a slight movement ruins the quality

The images are great, just the one thing that is bothersome.
I believe the blur effect on moving objects could be due to low light. Shutter speed on Auto mode could be at higher value for a moving object. Try increasing the ISO all the way to 3200 and setting S at 1/80 (or 1/60).

Even at daylight, the blur is present when object is moving
You need to use manual mode as mentioned by others
Hi
I'm not sure if the Galaxy S8 is able to do this but how can you get DSLR style focus where a subject/ person is in focus and background blurry? Can the rear camera do this as well as selfie cam? I haven't seen any options for it.
Seems only the Note 8 has this (or iPhone X, Google Pixel 2)?
Note 8 has second cam, which is x2 telephoto lens, so already has shallower focus depth and rest is done with software. S8 does not have second cam.
And here is the problem: blurred background, called bokeh, is mostly used in portrait photography. Wide angle cams so commonly used on phones should not be used for portrait photography, because due to wide field of view being projected on flat surface you get big distortions and wrong proportion, like big nose for example. Check fish eye lens pictures to see this distortion effect fully. So while you could distort background and make portrait photo with standard phone lens like s8 have, it would look silly. Outside of portrait photos I don't see much use for shallow depth of field, but if you're so inclined you could experiment with photo editing software like photoshop and create same effect. Expect S9 to have dual lens and portrait capability in about 6 months or get Note 8 now if you really want it.

there's an app that does this function very well. AfterFocus. the pro version lets you save in original quality. It only takes a few minutes to get the same result from dual camera devices.
Selective Focus is one of the camera modes out of the box. That is what you are looking for.
I have an S8 and have tried the selective focus mode, which works relatively well as long as the object stays still long enough, however I was reading an article about the Pixel 2 this morning and this extract made me hope that Samsung can also follow Google
"The single-lens portrait mode photos were made possible by its adoption of a dual-pixel sensor - meaning each pixel can be used to both record the image and determine focus rather than just one or the other.
Some of Samsung's handsets already feature the technology, but Google has built on it with proprietary software to make it possible to create a depth map for photos, which can be used to add special effects."
I hope that Samsung can improve the selective mode for the rear camera as the S8 also has a dual-pixel set up, unfortunately the front camera doesn't have dual-pixels
Another thing is I'm hoping that the Google Camera app, which I have running on my S8, should get an update to support this....fingers crossed.
