+# Zanya's Custom HDR Dataset
+

+  
+## Dataset Summary
+
+This dataset contains HDR images rendered from blender. Each image is of CC0 from various sources, organized into folders by the source.
+
+Images were taken at one of three resolutions:
+
+- (1920, 1080),  # Landscape
+  
+- (1080, 1920),  # Portrait
+  
+- (1440, 1440)   # Square
+  
+
+They were also given a random background colour from the following options:
+
+```python
+background_colors = [
+        ('white', (1, 1, 1)),
+        ('red', (1, 0, 0)),
+        ('green', (0, 1, 0)),
+        ('blue', (0, 0, 1)),
+        ('yellow', (1, 1, 0)),
+        ('purple', (0.5, 0, 0.5)),
+        ('cyan', (0, 1, 1)),
+        ('magenta', (1, 0, 1)),
+        ('orange', (1, 0.5, 0)),
+        ('black', (0, 0, 0))
+    ]
+```
+  
+For each object, images were taken at 0, 45, and 90 degress vertical, and 0 to 315 degress in 45 degree increments horizontally around the object.
+  
+
+Alongside the HDR image and jpg preview, a text file is included for each item with an example prompt which might fit the image, in the format of:
+
+"A render of {clean_name} with 4k textures in a completely {color_name} room with {color_name} lighting at {vertical_angle} degrees elevation and {horizontal_angle} degrees azimuth"
