SnailCamera is an outstanding camera app!
Custom filters many tools and settings four shooting modes let you do quite unusual photos like:
• long exposures (bulb mode or "B mode") to obtain a blur effect or pictures with in-motion details (clouds waves shadows lights for lightpainting etc.) - you may want a stand or a tripod
• multi exposures on the same image (multi mode) for artistic compositions
• full range brightness-contrast-saturation controls with realtime preview
• noise reduction algorithm for low-light conditions
• controls for all parameters (flash white balance focus scenes zoom effects) supported by hardware
• HDR acquisition and tonemapping tools (can correct exposition and histogram later inside the editor)
• image editor with brightness contrast and saturation controls and histogram correction tools (white level black level gamma-cosine equalization)
• 4 shooting modes (Normal Enhanced Multi Bulb) and more coming!
• support of all available preview resolutions (live-view) for both realtime effects and image editing
• support of all available high resolutions (normal mode only) for professional shots
• self timer (available delays: 2 5 10 seconds)
• bracketing (multiple exposures with user-settable compensation)
• share button available after each image is saved
