Trying to capture good Depth Of Field

I used a Nikon D90 with Nikon 16-85mm lens. After I took the photos, I imported them into a Microsoft Word document for an article I wrote on the subject. When I save the images out of the Word document, it strips away most of the data. I will look for the original files. I'll post again with the information.
Thanks. I was just wondering about all those variables.
WOA!~. I am sitting outside on my patio and I got my daily afternoon hummingbird visit. The little guy flys up suddenly close, within a meter, (3.3’) hovers for 1 sec, then departs. Pretty much every day I sit outside.

Not too sure how this became a discussion of diffraction when the question was about depth of field. There was a reason AA and the other "f64" folks called themselves the "f64 Club"...they loved achieving the tremendous dof at f64.

The discussion about diffraction came up because diffraction becomes worse with very small aperture settings.

Because they are related subjects (apparent sharpness) - the resolution of an imaging system is ultimately limited by diffraction. Remember that the f64 aperture you’re referring to was on large format cameras, not 35mm, and the effects of diffraction are substantially more pronounced on smaller film or higher pixel density digital cameras. If you’re ready for a more technical explanation and a discussion of the airy disc, I can post some references, but here’s a quick read by KR that I came across on the subject along with some examples: https://kenrockwell.com/tech/diffraction.htm

Why hasn't the OP made any further comments after the original post? Have we been attempting to assist a visitor from another world? Or the Ghost of Visions Past?
