IHF- I kind of get what you’re trying to say, but I think you missed part of the point of my illustration/experiment. For one, I cannot use the same lens on all three cameras. Obviously a point-and-shoot you cannot change the lens. The Rebel kit lens will not work on a full-frame camera as it’s an EF-S mount lens. I have, and do, often use my Sigma 70-200 lens on the Rebel, and yes, it does improve the quality over the kit lens (I actually bought it to replace the kit zoom lens, the EF-S 55-250 f/4.0-5.6 because I was sorely disappointed in the lack of sharpness). But when you put a telephoto lens on a crop sensor body you must increase your subject-to-camera distance to get the same DOF compression, therefore, the further you are, the more risk for camera shake and clarity issues which I have noticed myself. The Sigma lens works seamlessly on the full-frame body.
As for intent, you can get a great image on a cheaper camera and with an ok lens if you really try. Heck I know I have. But the point I was making again is that a person who doesn’t feel the need to invest in better equipment may also be the type of person who doesn’t care about all the little things or take extra care in posing, relation to the subject, composition, etc. Not to say they always are this type, but it’s more likely. Just like Cameraclicker suggested.
Also I used to think shooting in RAW was somewhat unnecessary, but once I started doing it, I realized how huge of a difference it makes. Whether I’m shooting in Jpg or RAW, I still try to get the image right in the camera. I don’t just haphazardly shoot with the knowledge that I can just fix everything later, because you can still only fix it so much without it looking weird. Sometimes I don’t set my white balance for the setting in-camera though, so that is probably the only thing I fall short on because I know how easy it is to fix in Lightroom. Quality is lost. Even the sharpness of a photo is lacking slightly when I shoot in Jpg. I think you’re saying that the image from the Elph and from the Rebel were processed because they were shot in Jpg right? So the camera “processed” them? None of the images above had any processing after downloading. The RAW image was exported as a Jpg right away.
Cameraclicker- you pretty much hit the nail on the head with your interpretation and that is exactly what my illustration was trying to show.
