Provoke Camera vs DoF Visualizer

Doesn't support iPads. Developed in collaboration with Glyn Evans [the founder of iPhoneography], Provoke Camera was inspired by Japanese photographers of the late 1960’s like Daido Moriyama, Takuma Nakahira and Yutaka Takanashi. Simple, elegant and easy to use, Provoke Camera does just one thing, produce black and white images with that gritty, grainy, blurry look reminiscent of the “Provoke” era of photography, and in two great formats; square format 126 and 35mm format 135. Provoke Camera features 9 great black and white and 4 color live view effects, in 2 great film formats, 126 [1:1] and 135 [3:2]: 1. HPAN High Contrast 2. NPAN Normal 3. LPAN Low Contrast 4. X800 More High Contrast with more noise. 5. I800 IR like filter. 6. Z800 +2EV with more noise. 7. D100 Darken with Blur (4Pixel) 8. H100 High Contrast with Blur(4Pixel) 9. E100 +1.5EV with Blur(4Pixel) 10. Nofilter 11. 100 Old Color 12. 100U Vivid and Sharp 13. 160N Soft In addition to capturing beautiful, gritty, grainy, contrasty black and white images, Provoke Camera will also allow you to import photos from your camera roll and apply any one of its “Provoke” effects. And Support TIFF Uncompress image file. Also support Photo Extension with iOS8 later. You can use Provoke Filter in Photos App.

DoF Visualizer — Ten Visual Tools for Photographers Stop guessing what your gear will do. DoF Visualizer turns the math behind photography into clear, interactive diagrams you can read at a glance. Drag a slider and watch the focus zone shift, the bokeh balls grow, the star trails appear. Plan the shot before you press the shutter. Built for photographers who care about why their images look the way they do — from portrait shooters chasing creamy backgrounds, to landscape photographers planning silky water, to astrophotographers timing their exposures, to macro shooters stacking focus on a single flower. TEN TOOLS IN ONE APP • Depth of Field — See exactly what's sharp. Live cone visualization with near focus, far focus, and hyperfocal distance for any lens, aperture, and sensor. • Hyperfocal Distance — Maximize depth of field for landscapes. Watch the in-focus band slide and stretch as the aperture changes, with an animate-aperture demo that shows the effect at a glance. • Bokeh — Preview background blur before you shoot. Adjust focal length, aperture, subject distance and background distance to see how big those bokeh balls will actually be. • Diffraction — Watch the Airy disk grow across your sensor's pixel grid. Find the aperture where diffraction starts robbing detail on your specific megapixel count. • Focus Stacking — Plan macro stacks. Tell it your subject depth and it returns the number of shots and the focus step in millimeters, with every slice's depth of field visualized. • Crop Compare — One focal length, four sensors. See concentric framing rectangles for Micro 4/3, APS-C, Full Frame, and Medium Format, with equivalent focal lengths labeled. • Nodal Rail — Estimate the no-parallax-point offset for stitched panoramas. Save calibrated values per lens and recall them with a tap. • ND Filter — Long-exposure planner. Pick your base shutter and target exposure, get the exact stops needed and the nearest standard ND filter. • Astro — Maximum exposure for sharp stars, using the modern NPF rule (more accurate than the 500 rule for high-megapixel sensors). Stars stay as dots — or sprout trails when you push past the limit. • Sun — Sunrise, sunset, solar noon, day length, golden hour, and civil twilight at your GPS location. Computed locally, no internet required. The on-screen arc even rises and falls with the season. DESIGNED FOR THE WAY PHOTOGRAPHERS THINK • Real lenses, real focal lengths — 8 mm through 1200 mm, the focal lengths actual lenses are built for. • All four common formats — Micro 4/3, APS-C, Full Frame, and Medium Format, with the correct circle of confusion and sensor dimensions. • Interactive visualizations — Every slider updates a live diagram. No number-crunching, no spreadsheets, no guessing. • Works anywhere — All calculations run on-device. No accounts, no ads, no subscriptions, no network required (location is used only by the Sun tool, and only with your permission). • Clean and fast — Native SwiftUI. Open the app, tap a tool, start planning. WHO IT'S FOR • Portrait photographers picking the right aperture for soft backgrounds. • Landscape photographers timing long exposures and dialing in hyperfocal distance. • Astrophotographers calculating their max shutter speed and timing the blue hour. • Macro photographers planning focus-stacking sequences. • Videographers and panorama shooters working with nodal rails. • Anyone shooting at golden hour and needing the times for tonight's location. • Students learning the optics behind their gear. • Anyone shopping for a new lens, sensor, or filter and wanting to see what it'll actually do. Take the guesswork out of every shot. See the physics, then make the photo.
