User guide

The live filtered view is always on the top screen. When you see something you like, just save it.

The bottom screen has tabs: "Camera", "Settings", "Gallery", and more. Tap either label to switch.

Camera tab

Four sliders let you adjust the look in real time:

• Brightness - Lighter or darker overall
• Contrast - Pushes darks and lights further apart
• Saturation - Left = greyscale, Right = vivid colour
• Gamma - Lifts or deepens the midtones
• Pixel Size - Adds a pixelation effect (snaps to 8 steps)

Below the sliders are 6 palette buttons, tap one to apply that colour palette. L/R cycle through them with buttons.

Palettes (Default):

• GB Greens (Classic 4-colour Game Boy green)
• GB Grays (Monochrome greyscale)
• GBC Greenish (Game Boy Color green tones)
• GBC Shell (Colourful, inspired by GBC shell colours)
• GBA-like UI (Game Boy Advance UI colours)
• DB Retro (Darkbox retro palette)

Filters:

• Lomo - colour-shift and vignette effects.
• Bending - warps and distorts the image geometry.
• Frames & Stickers - overlay pixel-art frames and stickers on your photos.

Wiggles:

• Take a burst of frames and save them as an animated GIF. Great for lo-fi motion shots.

Timer:

• Set a countdown before the shutter fires, useful for selfies or group shots.

Settings tab

Settings tab options:

• Save Scale - 1× saves at 400×240, 2× saves at 800×480 (default).
• Dither Mode - How colours blend at palette edges: Bayer, Cluster, Atkinson, or Floyd-Steinberg
• Invert - Flips all colours to their negative

From within the Settings tab, two extra tabs appear in the tab bar:

• Calibrate - Adjust the min, max, and default value for each filter slider
• Palette - Edit each palette's colours with RGB sliders; the top screen shows a live preview.

When you've set things up the way you like, tap "Save as Default" to write your settings to the SD card. They'll be there the next time you open the app.

Gallery tab

Tap Gallery in the tab bar to browse photos you've already saved.

Use the D-Pad to move between photos. The selected photo shows full-screen on the top screen.

Resetting to defaults

All your settings are stored in one plain-text file on the SD card:

sdmc:/3ds/pixelpix3d/settings.ini

To reset everything back to factory defaults, delete that file. The app will recreate it with defaults the next time you tap "Save as Default".

You can also open settings.ini on a computer and edit values manually, it's just key=value pairs.
