how would I go about creating an HDR in blender?

Here’s a practical way to **create an HDR environment map in Blender** (the usual meaning of “make an HDR” in Blender).
## 1. Build or load your scene
Place lights, emissive materials, and geometry as you want them to appear in the environment. The world shader can also contribute (sky, gradients, etc.).
## 2. Use an equirectangular panorama camera
1. Add a **Camera** (or use the default).
2. In the **Output Properties** → **Dimensions**, set an aspect that matches a full 360° strip, e.g. **2:1** (width = 2× height), such as **4096 × 2048** or **8192 × 4096** for higher quality.
3. Select the camera → **Object Data Properties** → **Lens**:
- **Type**: **Panoramic**
- **Panorama Type**: **Equirectangular**
4. Position the camera where the “viewer” should stand (often world origin). For interiors, put it inside the room; scale/orientation of the scene should match how you want the HDRI to look.
## 3. Render with a high dynamic range format
1. **Render Properties** → set **Render Engine** (Cycles is typical for lighting-quality HDRIs).
2. **Output Properties** → **Output**:
- **File Format**: **OpenEXR** (best for HDR; wide industry use) or **Radiance HDR** (`.hdr`) if you need that specific format.
- For OpenEXR, use **Float (Full)** / **Half** as needed for file size vs. precision.
3. **Render** → **Render Image** (F12). You get a single equirectangular HDR frame.
## 4. Use or share it
- In Blender: **World** → **Surface** → **Environment Texture**, load the `.exr` or `.hdr`, set **Color Space** to match (often **Linear** for EXR used as lighting data).
- Elsewhere: many tools expect **lat-long / equirectangular** EXR or HDR for IBL.
## Tips
- **Samples**: raise them enough that noise is acceptable; HDRI resolution amplifies any grain.
- **Exposure**: balance in-camera or in compositing; EXR preserves headroom.
- **Seams**: avoid obvious discontinuities at the left/right wrap by keeping large emissive panels away from the seam if possible, or fix in compositing.
If you meant **HDR stills of a normal perspective** (not a 360° map), say so—the steps are different (regular camera + EXR/OpenEXR output, no panoramic camera).

I got it, it looks sweet. can you take @blends/stills/Orb_channelpoints.png and re-export the 112,56, and 28 versions? I believe I have pillow installed.
