Can a DSLR take a better photo of artworks than a Point and Shoot Camera (Nikon B500)?

by Vikas Kumar   Last Updated June 01, 2019 15:18 PM

These photos are taken from my Nikon B500 Point and Shoot camera. See the Orange marks here.

The area nearby these marks is not well photographed. I guess you might not see much difference but as I have the original drawings, I know those spots missed details and it captures better from the middle only.

Secondly, there's always some noise. My drawings on paper are little better than they look here in Photographs.

So if I click the same drawings with a DSLR like Canon 200D, will I get better photos?

It isn't so much the camera body itself (that's just a sensor) -- it's more about the lens (photographer's understanding of the task is always important as well).

Mostly what the DSLR camera body offers... is the ability to change lenses to something more optimally suited for the task.

Optimizing Field curvature

A lens focuses to different distances and we tend to think of that focused distance as a flat plane. In reality it is slightly curved. This means that when you have the best possible focus at the center, the edges will likely be just slightly less focused due to field curvature.

A true macro lens is usually optically designed to do a better job controlling field flatness and may produce a well-corrected field all the way out to the corners.

I did mention photographer's knowledge in the mix because just having the right lens isn't necessarily enough.

Optimizing Aperture Selection

Few lenses will produce their best results if the f-stop is set to shoot "wide open" (lowest possible focal-ratio that the lens can offer). You'll generally get better results by slightly stopping down the lens f-stop. This varies by lens, but is often somewhere around 2 f-stops from "wide open". (Test this for your specific lens because it does vary by lens model.)

Optimizing Focus Point Selection

If you've still got a bit of field curvature and want to improve the overall focus, move the focus point. If the center is most in focus and the corners are the most out of focus... consider selecting a point about 1/3rd of the way from the center of the frame. This is the new area of best focus. The center of the frame is no longer the best ... but it's not far away so focus is still very good here. But this trade-off now means that the corners of the frame are now much closer to optimal focus than they were previously. The overall focus quality on the entire field will improve.
