It is also possible to specify an ND filter of up to 30 stops, handy for those long exposure photographs to blur water and clouds.

Please contact me if you'd like to have the app translated into your language.

Simply specify the filters used and the exposure time of the camera and ND filter calculates the optimum time span, for your photographs to become awesomet!

Features:
- Add your own filters
- Delete the default filter
- Select multiple filters
- Built-in timer / alarm
- Easy to use
- Automatic time conversion

For more information about gray filter / neutral density filter visit Wikipedia:
http://en.wikipedia.org/wiki/Neutral_density_filter

Select the shutter speed applicable without the filter then select the filter you intend on using. The shutter speed you will then need to use will be displayed with the timer available if it is 4 seconds or longer.

Current features:
- Shutter speeds 1/8000 to 30 seconds at 1/3 stop intervals
- Single 1 to 10 F-stop filters
- Timer complete notifications supported on Android Wear devices

How does this work ?
The App is based on an acoustic measurement-method: When you release the shutter of a camera, it makes a shutter-release-sound, which is caused by the opening and closing of the shutter. The App records this sound and displays a graphical waveform of it on the screen. Both the opening and the closing of the shutter produce a peak in the waveform. The distance between those peaks equals the shutter-speed.

Of course, the accuracy of this acoustic measurement has it's limits. It will give good results with slow speeds up to about 1/30 and 1/60. Leaf-shutters work better than SLR's and focal-plane-shutters, because they produce less noise which distorts the signal.

If you want more accuracy and be able to measure speeds up to 1/500, you can purchase a "PhotoPlug". This is a hardware-extension for the app, which allows you to measure the actual amount of light passing through the camera, instead of sound. The PhotoPlug is a small, 3cm long device which fits into the headphone jack of our smartphone. Once it is plugged in, it converts light into electrical signals, allowing you to make real light-measurements with your smartphone !

Although in the current market, there are have many kinds of camera applications, but we still think this android native application is the most efficient and able to meet a user needs. Here only as a supplement for those devices are not installed android native system provides an additional option.

Notes:
The special permissions for use
1, android.permission.ACCESS_FINE_LOCATION
HD Camera can remember your photos and videos location if you wish. Other apps can access this information along with your saved images.

2, android.permission.READ_CONTACTS
After you take a photo, you can share with others. HD Camera need to read the contacts information and help you share photos via email, SMS, or other apps.

Major features:

● All photographic parameters are adjustable and always at hand: exposure compensation, ISO, light metering mode, focus mode, white balance and program mode.
● DSLR-like viewfinder display: see exposure time, aperture and stops display with EV and bracketing settings, in real-time!
● Full fledged exposure bracketing: from 3 to 7 frames, unlimited stops spacing, plus custom EV shifting.
● Built-in intervalometer: make stunning timelapses (even bracketed/HDR timelapses) and time-controlled picture series.
● Program and Speed-priority modes.
● Long exposure support: take beautiful night photos and light trails with long exposure times up to 30 seconds**.
● JPEG, true 16-bit RAW in DNG format*, and lossless PNG photo capturing formats, perfect for post-processing.

● The most advanced electronic viewfinder: live RGB histogram, 10 composition grid overlays and 9 crop guides available.
● Powerful organization options: different storage locations and fully customizable file names (even with variables).
● The user interface is available in more than 30 languages.

This camera application completely avoids scene modes, instead you get full manual control over all photographic parameters, just like you do with a reflex camera, so you can ultimately control every aspect of the picture, and leave the post-processing to the computer. So after your DSLR, you will never miss a photo opportunity again, being able to capture it with the closer sensation to your DSLR as possible.

The Lite version is a fully functional version of Camera FV-5, with limited picture resolution support. Please buy Pro version to unlock all your device's resolutions and enable RAW capture (if it is supported on your device).

* Requires Android 5.0+ and a fully compliant Camera2 implementation. Currently only LG Nexus 5 and Motorola Nexus 6.
** Requires Android 5.0+. Compatible as well on the Samsung Galaxy Camera (1 and 2), Galaxy S4 Zoom and HTC One (M8). On Android 4.4 or older, long exposures lowers picture resolution to 2 or 1 MP, depending models. The reason is explained here: http://www.camerafv5.com/faq.php#long-exposure-resolution

This app has a lot to offer:
- Stopwatch
- Shutter speed calculator
- Countdown
- Start and stop buttons.
- Number pickers to select ND filters and shutter speeds as fast as possible.

The first version of ND watch is here!
This app is available now for android 4.0 - 4.4. Other android versions will be supported soon.
Please e-mail us with your feedback and idea's on how we can further improve NDwatch.

1. Switch to M mode (or S)
2. Find proper exposure without the filter
3. Put the filter on
4. Dial shutter speed to the value ND Filter tells you
5. Take a shot!

The formula we use to calculate the values is Tnd = T0 * 2^nd, where Tnd is shutter speed with the filter, T0 is shutter speed without the filter and nd is filter density (1, 2, 3, ... 13).

Code for the app is available at https://github.com/nciric/NDFilter.

Hold down the shutter button for continuous image shooting.
View captured images in a gallery and playback the sequence.
Supports forward and backward playback.

The high-speed imaging capability of this app allows you to capture events that unfold too fast to be captured by regular camera apps.

- Gallery
- Playback of image sequences
- Create GIF from images
- Zoom by pinch gesture or volume buttons
- Front facing camera support
- Select image resolution
- Silent, no shutter sound
- Focus by touching the screen
- Auto image rotation
- Easily share images

The following is available with in-app purchase:
- Flashlight (varies by device).
- High resolution
- Ad Free

Tips: Keep the camera steady while capturing high-speed images to get the best result. Ensure that the scene is well lit to reach the highest possible speed and avoid image smearing (e.g.: daylight, outdoors). The less light in the scene, the longer the camera’s shutter needs to stay open for capturing single frames (hence more time is required per image).

Hold down the capture button for high speed/burst mode image capture.
Photos will start saving as soon as you release the capture button.

To select all images in the gallery use the device options/settings button to show the menu.

The GIF creator function allows you to easily upload generated GIFs to social networking services.
Further, the GIF settings screens allows you to easily select a subset of the available photos and adjust playback direction, speed and image skip intervals.

Resolution settings indicated in screenshots may vary by device. It is advised that you experiment with different resolution settings to get the most out of the fast camera functionality. As indicated on the settings screen, high resolution images will, in some cases, lead to slower image capture and saving. Testing on high-end devices have however indicated that high resolution images does not affect capture speed (reaching 30 images/sec at full HD resolution).

We hope you enjoy this high-speed camera app with burst mode capability.

Do not hesitate to contact us if you experience any difficulties using this app, we are here for your support!
We will refund any purchase if we are unable to fix serious issues that you might experience.

Bottom line: If you want a fast camera, get this app!

Note: Flashlight and zoom features depend on device. Burst speed depends on device capability.
This app is intended to provide fast camera functionality,
to achieve this we can only provide certain (device specific) resolution settings.
Low-end devices may only get 10-15 images per second.
