The problem with your comment, Douglass, is that it might apply more to you that to those you direct it at! Posting images that are pretty does not prove a point. Claiming no credibility for those who have not posted unrelated images is just a diversion to avoid the requirement of providing good, detailed, and most of all accurate, information. Pretty pictures do not do that...

You've repeatedly made this claim about people needing to post images to UHH for credibility. Even when people have massive examples of their work elsewhere on the Internet.

Other bold statements, such as this one, "You cite my documentation; where is yours? Claims without documentation are merely opinion, of which you have plenty." are similar. They attempt to divert attention from valid facts that contradict your opinions. You might remember that one in particular, where you said of a 35mm lens "Adding extension tubes to this lens to reach 1:1 mag would be physically quite long (ungainly)", and became very intolerant ( "NONE of this is factual." ) when it was pointed out that a 29mm extension tube would produce 1:1 with that lens. But it was, just as the above, a diversion because you had not validated the facts. You in fact had not cited documentation that supported your point, but like pretty pictures just something with pretty words.

It does appear that you resent people who do validate facts and know how to explain them. Absent pretty pictures that mean nothing, of course... :-)

There are times I could have posted a picture here to help someone's understanding, but it would have been more to show the use of certain equipment rather than the results of using it. There are enough other sections for my blunders.

Perhaps I should also make it clear that I do on occasion post a picture specifically to illustrate a point. But I make it a picture that does exactly that, not just any pretty picture in some way related to the topic.

And while I only post a picture otherwise on extremely rare occasions, I think it is perfectly reasonable that people do post a variety of images here on a regular basis! Everyone has different ways to validate themselves as a photographer, and comparing notes with others on an Internet forum might be very useful for some but may have zero value for others.

On the other hand, I get my validation from prints that people pay money for... which is also quite reasonable, I think. :-)

Here's an example of photomacrography that I'll post a thumbnail and a relatively small version of, but absolutely will not post a full sized copy.

Nope not the same at all. Bracketing is where one varies the amount of light (exposure) but focus staking is where one varies the depth of field. With focus staking one takes multiple exposure of the same subject all with the same exposure but the focal point varies. When completed the pictures are fused together to get a stupendous photo because of clarity. This works great in macro photography.

Actually, when focus stacking you are bracketing the focal point rather than exposure. The links Nikonian provided will explain the procedure, and you can do a Google search for more resources. It's a fascinating method to achieve incredible depth of field.

Sand Verbena and Desert Primrose were too mundane, so when I got my first DSLR (Fuji S3 Pro) 9 years ago I went to the local rose garden for some real exotic stuff. This was a raw file exported as TIFF, no PP and saved for web. I won't post most of my best work either.
