SUMMARY

This discussion compares image quality among three camera types: an LG Smartphone with an 8MP sensor, a Canon 630 point & shoot with a 6MP sensor, and a Canon Rebel DSLR with a 10MP sensor. Participants noted minimal differences in image quality under controlled conditions, suggesting that factors like lens size, pixel density, and post-processing capabilities play significant roles. The consensus is that while DSLRs offer more features and flexibility, the differences in image quality may not justify the higher cost for casual photography.

PREREQUISITES
  • Understanding of camera specifications such as megapixels and sensor types
  • Familiarity with image processing techniques, particularly in Photoshop
  • Knowledge of optical principles related to lens and depth of field
  • Experience with different lighting conditions and their effects on photography
NEXT STEPS
  • Explore advanced DSLR features, including lens interchangeability and aperture control
  • Research techniques for low-light photography and noise reduction
  • Learn about post-processing methods in software like Adobe Photoshop and DxO
  • Conduct comparative tests using various subjects and lighting conditions to assess camera performance
USEFUL FOR

Photographers, hobbyists, and anyone interested in understanding the practical differences between smartphone, point & shoot, and DSLR cameras in real-world scenarios.

Yes.

My reading of this whole thread is that you try to convince us that a in a 30km/h zone with speed bumps every 10m a Nissan Micra performs as well as a 5 series BWM or a Ferrari. That may be the case, but I fail to see the relevance of this particular test.

Nothing personal, but I just don't get the point you are trying to make.

Your analogy is spot-on. But I was not trying to convince anyone; I have merely been expressing my own pre-expectations. I did indeed expect the Beemer to perform better at 30km/h. It took me some convincing to concede that they should perform similarly.

Surely they must be able to do the same thing. They are basically the same, internal combustion engine, a heap of gears and some wheels :-)

Anyways, the right tool for the right job. The Ferrari does not fit in my garage and cannot deal with the potholes around here.

The camera phone did perform better than I expected, see my first post. But note that most people correctly identified the DSLR pic

I'd suggest taking pictures of plucked guitar strings and your cityscape at night.
