You mention using RAW is better, but then you import JPEG in the example. Should we import RAW (in my case .CR2 files) or convert them to JPEG ? Thank you
just standard, if you are getting close enough to use a macro it throws up issues with short depth of field, which can be tackled with focus stacking but it's a can of worms best avoided unless you are scanning insects or super tiny things.
wow my mind just asked me if he was real even or 3d. because i just started to wonder what if they were testing people to see or show them you can't tell the difference between real life and mastered reality capture :D that light on half his face was part of what made me wonder. testing two different light patterns on the face to see if anyone could tell or guess. or maybe to mask or hide a slight problem with it? nah i'm probably just being... over imaginative. or am I
Can you show us the desktop continuesly instead of switching to a talking head. I want to follow the procedure using RC. What is a UV, udem etc? Please introduce the terminology. Oh, next time in 4k pls instead of old fashioned 1080p.

**Introduction and Overview:**
- **0:01**: Introduction by Wallace from the product team at Capturing Reality, focusing on photogrammetry and the Reality Capture and Reality Scan software.
- **0:19**: Overview of photogrammetry principles and common issues.
**Principles of Photogrammetry:**
- **1:00**: Scanning involves capturing many images from different angles to create a 3D model using software.
- **1:20**: Laser scans and camera rigs, as well as drones with RTK GPS, can improve accuracy.
- **2:08**: Key considerations: image quality, overlap, and subject coverage.
- **3:05**: Image quality and surface features are crucial; blurry images and noise can cause problems.
- **3:44**: Overlap is essential; 70% is a good rule of thumb, but more overlap can improve results.
- **4:34**: General photogrammetry process: capturing images, processing with Reality Capture, and exporting as a 3D model.
**Photogrammetry Equipment:**
- **5:01**: Equipment includes cameras (mobile phones, DSLRs), lenses, tripods, rulers, color checkers, lighting equipment, and polarization filters.
- **7:38**: Using drones for large objects, turntables for small objects, and scanning sprays for shiny objects.
- **9:05**: Additional gear includes smartphones, laptops for on-site processing, and practical items like batteries and power banks.
**Guidelines for Taking Photos:**
- **11:04**: Do not limit the image count; use high resolution; each point should be visible in at least two images; shoot full loops around the object; maintain high overlap; avoid panoramic images; avoid object movement; avoid transparent and shiny objects; maintain consistent lighting conditions.
- **12:47**: Importance of taking many photos and maintaining high resolution.
- **13:29**: Photography basics: aperture, shutter speed, and ISO settings are crucial for quality.
- **15:59**: Ensure each point is visible in at least two images; follow the shape of the object; maintain high overlap.
**Additional Tips:**
- **17:04**: Avoid changing the viewpoint more than 30°; keep the object in the frame; use high overlap to tie images together.
- **18:14**: Avoid tilting the camera; keep features visible in multiple images; avoid featureless textures and inconsistent lighting.
- **19:00**: Practical advice on dealing with featureless textures and maintaining consistent lighting.
**Dos and Don’ts:**

Fantastic presentation. Can't wait to try RealityCapture on a few objects. Thank you!
The depth mapping process is such a clever way to do it. Thanks for the information. @38:55
RC is a great app, one of the best.. it needs "only" a complete UI overhaul :)
You mention using RAW is better, but then you import JPEG in the example. Should we import RAW (in my case .CR2 files) or convert them to JPEG ? Thank you
Awesome
Can you post your power point presentation please.
Great
bro this guy was hilarious lol made me laugh and learn.
50mm standard prime or 50mm macro? Thanks!
Standard is fine, you aren't close enough to need a macro lens
@@hellomistershiftydepends on the size of the object you are scanning in.
just standard, if you are getting close enough to use a macro it throws up issues with short depth of field, which can be tackled with focus stacking but it's a can of worms best avoided unless you are scanning insects or super tiny things.

I can assure you if i made a 3d model of myself I would give myself better teeth :D
