I want to present you my camera app, Volshutter Camera.
I've made this camera because my phone doesn't have a dedicated hardware camera shutter and I cannot find on Market a solution that made me happy.
With Volshutter you can take photos using your volume rocker. Press it and hold to focus and release it to take a photo.
This camera have few features, but I'm including more very frequently. Now we have camera controls (focus, flash, resolution, white balance), sharing feature and post-processing effects (vignette, white burst, color filters).
Any question, suggestions and bug reports, just post here! =)
Reviews are welcome too!
You can find my app here on AndroidPIT
