[REQ]Long exposure photo application

I was wondering if there is any application on the net so you can take long exposure photos. http://en.wikipedia.org/wiki/Exposure_(photography)
hope im clear...
thnq very much

+1 on this, I'd kill to have something like that.

Lol.... better get a very nice tripod for your phone..

Interesting. Could be nice to have one, but I'm afraid I don't really have much need for it.

Funny while trying to accomplish a picture of the full moon this past week I dreamed of this exact feature. But i have to agree, without a tripod it would be a blurry mess.
The phone takes incredible close up pictures, or normal high res pictures when i set the focus to center. But without a way to steady the phone, it would be basically useless.
But i would still try it!! Hell yeah.

so till now nobody ever came across something like this???... ...it must possible right?..I just want a small application thats able to keep the shutter open for a few second...

I do not know of any application for this. However, even if you find one I am not sure you would like the results. Small very dense CMOS sensors like the ones in thee phones do not like long exposures. The sensor heats up quickly and creates tons of image noise that has to be removed in post processing. By the time you delete the noise, all the detail is gone as well. I have a $2.5K Leica that takes great pictures at normal exposures, but anything over 1/4 second is unusable to me.
If you want long digital exposures worth keeping, you really need to step up to a higher quality camera with a larger physical sensor. Oddly enough, the lower the megapixel count, the better the image will be.

Its a good idea but i dont think the picture would come out great. Since the phone's camera sensor is so small there would be A LOT of noise. Even on my Canon XSi with long exposures I get some noise, and the cameras sensor is about 20 times bigger than the phones.

And yet, my $1.8K Canon takes AMAZING long exposure shots, even up to 30 seconds.
here's one I setup in about 5 seconds a couple years ago: http://l3it3r.com/2007/bashir.jpg

Yes, my newer Nikon D700 does quite well with low-light and long exposures. I have done some 30 second exposures that just amaze me. The Leica is old by digital standards (4 years). I cannot wait to seewhat the next 4 years will bring. Maybe we can get rid of our flashes forever...

You could just take a video and then convert it to a long exposure photo using an app on your computer
http://www.nimisis.com/projects/exposure.php

I also just saw this app online, haven't tried it yet though.
http://www.androidzoom.com/android_applications/communication/time-exposure_nbeb.html
And the free version:
http://www.androidzoom.com/android_applications/entertainment/time-exposure-free_nbec.html

Iphone???
I know That iphone has one Called Magic Shutter and it replicates some amazing results. Now all we need is to port it to android

long exposure is awesome. even my $400 xti takes some excellent long exposure pictures.
I want to do timelapse star photography and I need 20+ second exposure times per shot. Grrrr.

Nexus 5 in the hands of a photographer

We gave our Nexus 5 in the hands of a photographer (friend of mine) for a month, and this is what we get!
Very impressive!

yup

There's some pretty severe pink-camera-problem going on in the center of most of the photos.

Wow, these look great.
Getting excited to see if I'll be able to get shots which look are remotely as good

and you had to get a photographer for those shots? :laugh:
anyways, OP has "generating clicks" written all over it.

Nice shots! I especially like how well OIS works on the n5 when taking videos too, much better than the n4.

I think that issue is pretty common these days, you camera might even produce those with the very same conditions.

Nice Pic's, probably could have been a litter better if it was from a White N5

I am assuming that your friend bit**ed and moaned about the lack of manual shutter speed and aperture control, default camera app (awful), and in general lack of a manual mode (which is how most pros shoot- manually setting everything).
Disclaimer: I'm a photographer (not the 'I have a DSLR and use AUTO mode and press this thingy' photographer, the 'I have my own successful business' kind) and the lack of manual shutter & aperture is beyond frustrating to me. Sure there are (mostly worthless) apps that give you some control of ISO, WB, burst mode, etc., but without those vital exposure controls (shutter and aperture) to me all smartphone cameras will suck.
I know, I know. It's not a pro level slr... it's a phone...

Of course having stunning locations always helps.

While I agree with you that the default camera app is incredibly awful and lacks many controls, mobile phones are replacing point and shoot cameras, not DSLRs or micro 4/3. Also, most people use photos nowadays for stupid web shots/social/ready-made-filters etc and not for printing or cropping and zooming for the perfect frame.
I replaced my Cannon P&S since I had the HTC One X two years ago, but no mobile will ever replace my Fuji X-A1

I don't disagree with you on anything but this - most modern SLR pros I know (less than 100, but many more than 10) do NOT shoot all manual. Most may shoot A-priority or S-priority, or use P mode and wheel their way to the desired blend, but only landscape, product or portrait shooters really can practically go all manual, all the time - you need non-moving subjects and somewhat consistent lighting to rock all manual and get a decent return on your shots.
And let's be fair, manual shooting modes do not make better pictures: better photographers make better pictures.

I know this and agree with you entirely, but I do have an old Polaroid P&S that allows me to set the shutter speed (like from 1/30-1/200, but no aperture control) and that thing is 5+ years old now. But yeah, the need to own a P&S is mostly non-existent with how good smartphone cameras are getting now. It still wouldn't stop me from griping about the things I mentioned if someone gave me a smartphone to take photos with the expectation of delivering pro quality work though (OP was 'I gave my phone to my pro friend to see what he/she could do').

The only problem I have with P, A, and S priority modes is the reaction time of the camera to lighting conditions - especially outdoors. I particularly have an issue with P mode as most cameras seem to want a neutral/balanced shutter and aperture - like 1/60 @ f8 - whereas I may want 1/125 or faster @ f4.5-6.3 - and it gets worse outdoors (like wanting 1/160 @ f25 instead of 1/800 @ f8 etc) almost necessitating use of S mode if auto operation is desired. It also seems to take too long sometimes for the camera to read the amount of light and adjust the exposure (shutter speed in A mode or aperture in S mode) correctly. Shooting in manual mode for me is easier and better for me as I can read the light and pick a proper shutter, etc. based on conditions where I am shooting without having to worry about being occasionally slightly too bright (concern for a loss of detail being washed out) or too dark (where softness/pixelation comes into play).
But I suppose how you use your camera will vary on what you are taking pictures of. My gripe with the Nexus 5 is that with adequate lighting indoors and having the flash on auto the camera seems to always want to take pictures with the flash off at 1/10 or 1/20 @ f10 ISO ~400 or something like that, and that's just no good with really anything especially pictures of the kids. Why can't I at least just set the shutter? So many blurry pics... I thought there would be more emphasis on getting the camera experience better on a Nexus phone... the sad thing is that the hardware is actually really good for a phone but sadly the software side is woefully behind :crying:
And let's be fair, manual shooting modes do not make better pictures: better photographers make better pictures.

Absolutely correct.

I always love these posts,
I have been an on again off again professional photographer for over 10 years mostly in industrial photography.
Even once owned an online photography magazine with pros writing articles from around the world.
My first thought is that it never really has much to do with the camera, its the photographer that stands behind this.
The best example I can give you of this, is the gear snobs that say you can't use mirror-less cameras in the professional setting.
Just grab a pro photographer give them a Nikon V1 or a Olympus OM-D and let them go shooting for a day.
As far as not having P/S/A/M modes, it's a phone....
1 in 100 000 people will even know what that is and about a third of those will actually know how to use it.
If we want to talk camera geek for a moment.
Sensor size is 1/3.2″
Aperture is f2.4 (fixed Aperture)
Max iso is 100 - 800
What does this mean?
Low light shots will still be grainy (Tiny sensor doesn't collect enough light)
The Lens is equivalent to about 28mm which if you have a Canon Rebel or a Nikon DXXXX camera it works out to the 18mm on a kit lens.
So why no manual control?
Well with a fixed aperture of 2.4 what can you change?
Well if you know cameras there is something called the exposure triangle, all this means is aperture, shutter speed, iso have to line up just right for an image to be exposed correctly. In A (aperture priority) you only control aperture and iso, S (shutter priority)you only control shutter and iso, and M you control everything. If you can't change the aperture then you can't use these modes.
Any app that says it gives you control of these things are just simulated.
Every photographers favorite word.... Bokeh!
The blur in the background, how to get it on a phone.
First we have to look at two things the 28mm lens and the tiny sensor. The smaller the sensor does not help at all in this case and nether does the focal length. To get Bokeh with your phone you have to get really really close to your subject almost as if your taking a macro shot.
One more trick for you guys if your still reading this, the camera phone is not ideal for taking portraits.
The reason why is at 28mm you get barrel distortion that pulls the center of the image towards the viewer. You can give people longer than usual noses and get strangeness going on. If your going to take a portrait of a person, instead of taking a close up on the face back up a bit. It will help hide this distortion.
Wow didn't mean for this to come out this long but I am at work, and bored.... lol

Picture and video quality

Omg
I'm trying to capture myself as accurately as possible
When I'm taking pictures with either camera or recording video the picture and video playback looks right.
When I go to transfer them to my computer the quality doesn't look the same as when I took the picture, my skin tone is off, primally, quality etc just looks not as good is it losing quality or something. ? I can be in my vanity mirror, take a picture and see two different people
Makes me self conscious when I'm looking back at them, even though I know it's not an accurate depiction of me but it deters me from wanting to use this camera because when I'm viewing the picture on the device it's much different on computer
This is dysfunctional

Maybe your pc needs an upgrade to the graphics card. 4k screen for it and some software bumps and you will probably see what u see on phone
BAD ASS NOTE 4

The note is 2k, my computer is HD. I only record in 1920x1080, and the camera's are usually on the highest megapixel setting. I just wish the replication was more accurate.

But yes, I will suggest you buy an actual camera if you are trying to go with all that real world qualities and what not.
You can also also buy Camera FV-5 from the playstore, fractions of a real camera and see what that can do for you. It is the most realistic camera shots I have seen out there You can also do a lot of customizations with it that you can with actual cameras...I'm not talking about samsung gimmicks or the many gimmics out there such as blurr and what ever else is out there.
P.S Procamera is also good.
P.P.S...sure its not your lighting? My note 4 camera depict me quite well -cheeky smiles-
Let me know how it goes for you!

Lol no I'm not a fan of selfies and bathroom mirrors I use my tripod 85% of the time. I want to be satisfied with the picture and just upload it and not have to tinker with the photo because it just doesn't look right. But you have a point some lighting it's great others it's just like who the hell is that Lol. That's why I just record videos instead, never really been photogenic but in person I get many compliments it's so funny up me Lol but I rather in real life where it counts then social media

Haha, definitely ...beside, we are our own worst critics!

Motion blur in pictures

Hi,
As a fairly new father I am taking a lot of pictures of my daughter.
In still shots the phone is fine but when she is moving, which can be quite a lot I am getting lot's of pictures of blurry arms and feet.
My wife says my new phone is rubbish and I should return it because of this, compared to her iphone 6 which takes perfect pictures of moving arms and legs with zero blur.
To be honest I never had a phone cause so much blur with the standard automatic mode...before this my P9 took pictures in the same circumstances with zero blurry limbs and my Lumia 950xl was perfect taking pictures of my dog.
Does anyone else have blur with moving people or animals?
Any tips on how I can avoid this problem?
I have turned off HDR and flash to try and reduce the time needed for each photo but I need to take photo's fast some times and don't have time to mess around in the settings.

Its not really a fault of the camera or the phone, it is attempting to get a correctly exposed shot with the light available and if there is a lot of movement in poor light the bits that are moving get blurred due to a slow shutter speed.
You might want to try using the colour sensor only although it is well known the camera app is a bit crap, you could try another like Camera Zoom FX etc.

Cheers for the reply,
I have opencamera installed but didn't really use it much so I'll give that a test over the next few days.

Trouble is comparing it with an iPhone isn't going to help either, i think the camera in the Nokia 8 gets a bad rap but clearly it cant compete with an iPhone which are known for having great cameras.

For sure, but I had a lot of phones with camera's over the years and didn't get blur as bad as this guy.
iphone 6 is 3 years old so I would expect it to produce better photo's than that (ignoring the blur factor), when I had my Lumia 950XL my wife was amazed at how good the photo's looked compared to her iphone.
If I can just find a better camera app than the default one it can be ok.

But did you try Google Camera on the dev section ? the BSG, Cstark or Arnova one ? There is zero shutter lag like Pixels, and it's very good.
You can't compete with Lumia 950XL though. Still a king after these years and incredible in low light

Age has nothing to do with it though, a good camera is a good camera, my (now little used) Canon 20D is 14 years old and still takes a cracking photo.
The f2 aperture is the weak point on the Nokia 8, even my Moto G5 Plus has an f1.7 aperture and sadly Nokia cant do anything to change that other than force the camera to shoot with a higher ISO and therefore a faster shutter in low light.

Use the google camera app. Turn on "HDR+ Enhanced" and you should not get blurry photo in decent/good light. A bit of delay per shot but you'll get great image.
The phone still gives up in low light, however.

Bit late here, but I have the same issue. I think the camera is ****. Even my old phones (and cheaper phones are significantly better at capturing moving targets). Really disappointed. Got new kitten, 1 in 10 photos is keepable. Even in bright light. It just takes way too long to focus, often missing the moment altogether.

Slow/blurry focus is already a common problem on Nokia 8. You can install the Google Camera to resolve the problem. It also comes with some new features (such as motion picture) which is currently and exclusively on Google Pixel 2 camera as well.??

Camera Settings and Taking Photos

Ive seen some of the photos that other people have taken with the P20 Pro and they look amazing.
I'm no professional photographer and don't pretend to be one. I just want to take photos of my children when on holidays, days out, events and birthdays etc.
Every photo I take seems like a good shot, until you zoom in on the photo, then the image becomes pixelated. Another thing that seems to happen a lot is colour fading, every shot looks washed out or like it's lacking vibrant colours.
I've got the Huawei P20 Pro mainly because the camera was classed as the current best in mobile phones. I feel like I either don't understand the camera or that doing something wrong.
Could anyone offer any advice.

Depends on shooting mode and how much light you have. If I try to shoot in Aperture Mode in low light, I get pixelated photos as well. From my 1 month experience with the phone, I can tell you the camera is far inferior to that of other current flagships (especially when shooting pictures of people), mostly because of software overprocessing. It will usually oversharpen the crap out of everything (especially when using the 3x zoom lens) and will destroy skin texture (regardless of beauty mode selection). I get wildly inconsistent quality across. While some pictures end up fine, most will look a lot better on-screen than on a computer. Also, the pictures will almost always be brightened after processing, which means that what you're seeing on screen when taking a picture is not how the final photo will look. I'm coming from a Samsung S7 and its camera provided very predictable (and sometimes maybe even better than Huawei's) results, where what I saw on screen is what I got. I'm quite disappointed by this phone. They really need to fix their software, but I doubt they'll ever do that.

I tend to just use the standard AI and have got (IMHO) some lovely pics without filters or tinkering. I've started an Instagram of some of my favourite P20 Pro pics - not sure if we are allowed to link to them on here these days ?

That's what I've been doing recently and they seem better than before.
I think we can link pictures as it's not advertising.

I've just started adding a few of (what I consider to be) my best shots.

I will admit, those are some nice photos.
I think I'm going to take some outside shots tomorrow and see what they turn out like.
I'll gladly share them with you, for comparison purposes.

I have the P20 Pro since few months and i compare it with S9, S9+, Pixel 2 and IPhone X, i assure you that this device have one of the best phone's camera in 2018, you can also look in the DXOMark that is the TOP-1, i came from Galaxy S7, and S7 have a good camera very similar with S8 and S9, but the versatiliy of the P20 Pro is far from them, also if you take pictures in sunny days with the 40mpx sensor, you will see that looks like a professional camera, its true that sometimes the IA is overworking the scene, but you can disable on the screen easy
