Hi!

I am a newbie using Ultra Fractal 6.02 (64-bit) and just started going through the Tutorials.

Q# 1. Is the default image size of all fractals 800 (w) by 600 (h) at 300 PPI?

Q # 2. At the end of the day, I want to render JPG images 16 inches (w) by 12 inches (h) at 300 PPI for giclee printing. How does the above size relate to the final rendering?

Thank you!

Dr. T

The default size can be anything you want it to be. Have a look at the Defaults tab of the Preferences dialog. You can make some decisions about your default here.

Alternatively, if you want something different to what the program ships with then you can create a suitable image yourself. Save the result and tell UF via that Prefs dialog to use your image instead whenever you start a new fractal.

As an example; I like to start with a portrait style image so I have my own default Mandelbrot layer that opens every time at 600 (w) by 900 (h) as I happen to like working with that 2:3 ratio.

As for printing you should just make sure you design your fractal with the same height/width ratio is the intended print so the overall composition will be the same.

In your example above the working & printing size ratios (4:3) DO match. So just set the desired size in inches on the render dialog and confirm the resolution required (300ppi).
You can check all is correct by switching to the pixel count for the render - you should see a result of 4800px x 3600px which is exactly what you would expect with those settings.

The resulting render will be perfect for a high quality 16" x 12" print.
