Tools and parameters

Parametric Literacy Tool

Upload an image, adjust parameters, and learn how visual effects decompose into explicit values. Generate structured prompts for AI collaboration.

What is Parametric Literacy?

Parametric literacy is the ability to understand and articulate visual outcomes as systematic configurations of adjustable parameters rather than vague stylistic descriptions.

Visualizing Image Data

Histogram Analysis: The graph represents tonal distribution. It is divided into Shadows (left), Midtones (center), and Highlights (right).
Reference base: The help popups cite selected sources on digital image processing, histogram/gamma correction, color processing, and gamut clipping. Use the DOI links inside each popup for more information.
Bibliography: Sinecen (2016), DOI 10.5772/63028; Peli (1992), DOI 10.1117/12.59989; Yang and Kwok (2003), DOI 10.1117/1.1544479; Subramani and Veluchamy (2020), DOI 10.1002/col.22502; Kadmin (2022), DOI 10.24996/ijs.2022.63.1.30; Oduncu et al. (2004), DOI 10.1177/1534734604268842.
Clipping / Data Loss: When you adjust extremely, pixels push off the edges (below 0 or above 255), destroying detail. Use "Show Clipping" under the canvas to visualize lost shadows (Blue) and highlights (Red).

1. Gemini 2.5 API Setup

Enter your Gemini API Key to enable AI features. It is stored locally in your browser's localStorage.

API setup, free access, and privacy notes

How to get a Gemini API key: open Google AI Studio, create or select an API key, and paste it above. Availability, rate limits, and pricing can change; always check the official Gemini API pricing and rate limits pages.

Privacy: core image editing runs locally in the browser. The current canvas image and active parameter context are sent to Gemini only when you click Analyze My Image. Metadata JSON exports do not include image pixels or API keys.

Other providers to explore: Other AI and image-transformation providers may be suitable for future experiments, but they are not currently integrated in this tool. Availability, pricing, and rate limits should always be checked in the official provider documentation.

AI Image Critic (Vision)

The AI will "look" at your current edited image and analyze its exposure, contrast, and color balance, suggesting specific improvements.
