yes.. try any aperture above F4.. as we have mentioned few times...... like maybe F5.6... or maybe even F8. You say you have a Psych degree, right.. so that intimates some intelligence on your part. Why don't you understand that your DOF is inadequate... and this is such an easy problem to fix.
I have posted several times trying to help.. this is the last one!!!!
I was suspecting that you were using the terminology incorrectly. This has become a huge, huge problem in recent years; for example, when cgipson says to use "any aperture above F4"...okay...well, that in my book is the wrong way to use the terminology of aperture AND f/stop nomenclature. Referring to a higher numerical value as an aperture "above F4" [sic] is simply an incorrect way to describe what to do.
The apertures "above" f/4 are the wider apertures, like f/2.8, f/2.5, f/2, f/1.8, and f/1.4 and f/1.2...that's what that "above" means in the parlance of photography in reference to apertures has been used for the last 100 years or so...this is so because when the photographer finds that the light meter indicates MORE light is needed, the lens must be "
opened UP"...and
above means "MORE" light, and not just a higher numerical value.
The OPPOSITE of "opening UP" the lens is
"Stopping the lens DOWN", which means using the smaller, more-narrow apertures like f/6.3, f/7.1, f/8, f/11,etc.
