SOP with ALL View Cameras, Jee ….

When we first came up to CT from Petersburg, VA, we lived with a family in Woodbury. They later moved to Shaker Heights. We would go and visit them there for a while - seemed like a nice enough area, alright!

Karin … what's the difference between a National Park and a State Park?

New Fairfield, CT (where I am) is the home of Squantz Pond State Park (see above - got a pic of the sign.)

Not sure if I've ever BEEN to a National Park ….

I know Newington fairly well … Berlin Turnpike and all that. Rocky Hill and East Hampton - not so well ….

What made you decide to move to Cleveland, Ohio?

TOY, huh, Bebu? …. Rig … Toy … Object of Desire … what's the diff?

Yes, that's true, Moto … glass is - virtually - unbreakable, and there are so few moving parts, too ….

Quite unlike your turbocharger, or any of your engines …

Unlike the bodies, themselves - which DO go down, every single year, until they acquire "Classic" status!

How NICE of the VA to do that for you, Moto … perhaps, now - you can actually BILL them - for your subsequent GAS ATTACK - which they've now caused, by their unfeeling ways …

Ah, I see. You could always move to Toledo, I guess - huh?

Oh, great, Karin … I have plenty more where THAT one came from. Where'd you grow up?

Your rig, Bebu - is your Df ….

Thumbnails definition from Wiki:

Thumbnails are reduced-size versions of pictures or videos, used to help in recognizing and organizing them, serving the same role for images as a normal text index does for words. In the age of digital images, visual search engines and image-organizing programs normally use thumbnails, as do most modern operating systems or desktop environments, such as Microsoft Windows, macOS, KDE (Linux) and GNOME (Linux). On web pages, they also avoid the need to download larger files unnecessarily.

Thumbnails are ideally implemented on web pages as separate, smaller copies of the original image, in part because one purpose of a thumbnail image on a web page is to reduce bandwidth and download time. Some web designers produce thumbnails with HTML or client-side scripting that makes the user's browser shrink the picture, rather than use a smaller copy of the image. This results in no saved bandwidth, and the visual quality of browser resizing is usually less than ideal. Displaying a significant part of the picture instead of the full frame can allow the use of a smaller thumbnail while maintaining recognizability. For example, when thumbnailing a full-body portrait of a person, it may be better to show the face slightly reduced than an indistinct figure. However, this may mislead the viewer about what the image contains, so is more suited to artistic presentations than searching or catalogue browsing.
In 2002, the court in the US case Kelly v. Arriba Soft Corporation ruled that it was fair use for Internet search engines to use thumbnail images to help web users find what they seek.

The word "thumbnail" is a reference to the human thumbnail and alludes to the small size of the image or picture, comparable to the size of the human thumbnail. While the earliest use of the word in this sense dates back to the 17th century, the American Heritage Dictionary of Idioms is reported to have documented that the expression first appears in the mid-19th century to refer to 'a drawing the size of the thumbnail'. The word was then used figuratively, in both noun and adjective form, to refer to anything small or concise, such as a biographical essay. The use of the word "thumbnail" in the specific context of computer images as 'a small graphical representation, as of a larger graphic, a page layout, etc.' appears to have been first used in the 1980s.

Dimensions
The Denver Public Library Digitization and Cataloguing Program produces thumbnails that are 160 pixels in the long dimension.
The California Digital Library Guidelines for Digital Images recommend 150-200 pixels for each dimension.
Picture Australia requires thumbnails to be 150 pixels in the long dimension.
The International Dunhuang Project Standards for Digitization and Image Management specifies a height of 96 pixels at 72 ppi.
DeviantArt automatically produces thumbnails that are maximum 150 pixels in the long dimension.
Flickr automatically produces thumbnails that are a maximum 240 pixels in the long dimension, or smaller 75×75 pixels. It also applies unsharp mask to them.
Picasa automatically produces thumbnails that are a maximum 144 pixels in the long dimension, or 160×160 pixels album thumbnails.
The term vignette is sometimes used to describe an image that is smaller than the original, larger than a thumbnail, but no more than 250 pixels in the long dimension.

Note: there is NOTHING in the above dimensions which correlate with your theory 640x480 images are somehow related to the term - THUMBNAIL!

Hereyago, Karin … here's one almost as colorful as that sky you put up …

Oh, very nice, Karin … a bit of Rocking and Rolling, there - huh?

Nice to hear back from your piers … er … peers - huh?

With regard to HOW did I/we - pick our current rigs - the answer to that (at least, as far as the Sony a77 II) is - that I was looking around for a body w/ IBIS, as I don't fully trust the ILIS in conventional DSLRs - since body shake - does NOT seem to be compensated, sufficiently enough, in ILIS based cameras, so that ruled out Nikon and Canon - for the most part. This left Pentax and Sony SLTs - both of which I delved into with varying degrees - Pentax K-50, initially - which, at first - produced the most fantastic images, and with only a 16MP sensor!!! … Now, with the 24MP sensor of the two Sony a77s I have, I've found my stride!!!

Primary rig, now - is the Sony alpha a77 II w/ a 16-105 DT. Yesterday, I took it out with my Sigma 105 Macro attached - got some extraordinarily good images, with it. My other Go-To camera is a Nikon D5500 with a Sigma 18-250 OS HSM Macro - seems to work well under many different situations. When I plan on working more precisely - I bring out one of my three Canons - either the Rebel T4i w/ 15-85 IS USM, or the EOS 60D w/ Tokina 16.5-135 AT-X, or my Rebel T3 with a Tamron 18-270 VC PZD. Back-up Nikons include the D5300 w/ Sigma 18-200 OS HSM, D7100 w/ 16-85 VR, and D7000 w/ Tokina 16.5-135 AT-X, as well.

Love the pink in the sky on that first one, Karin … has an almost surreal quality about it ….
