English: Used Zom-B's library with my own code and a golden gradient (similar to the default gradient used in Ultra Fractal). Each scene is 3x supersampled to remove sharp edges. Took... a while to render

Mandelbrot zoom with center at (-0.743643887037158704752191506114774, 0.131825904205311970493132056385139) and magnification 1 .. 3.18 × 10³¹ created using my own Java program, using:

• Double-double precision (self-written library),
• Adaptive maxiter depending on the inverse square root of the magnification
• Adaptive per-pixel antialiasing strength depending on the maximum iteration of nearby pixels (15x AA max), (during antialiasing phase, maxiter is quadrupled),
• Iteration smoothing,
• New warm gradient which also gives clearer details, applied to the base-2 log of the smoothed iteration number,
• Modified periodicity checking algorithm from Fractint, for significant speedup,
• Main cardioid and period-2 bulb checking for another speedup,
• Multi-threaded calculation
• 136 hours calculation time on two PC's (6 cores combined)
