Dino-Lite USB scopes - grepper - 07-12-2018
After seeing Mr. Cyrano’s images I did some checking out of the current Dino-Lite USB hand-held scopes. I must say I’m impressed. I also did some checking around and didn’t find any other scopes with similar features.
The two coolest features are focus stacking and exposure bracketing. Additionally the scopes can be focused with the keyboard which solves the hair pulling freak show of focusing USB cameras by having to touch the scope. Add to that they have an internal polarizing filter to help reduce reflection on surfaces.
Focus stacking and exposure bracketing is well known in photography, but I’ve never seen it before in USB scopes.
The following image is a great example of where focus stacking, exposure bracketing and a polarizing filter would be very beneficial.
Here the top part of the bevel is in focus, but is less focused at the edge. With focus stacking an image can be taken focused at the top of the bevel and then another focused on the edge. The two (or more) images are then combined so the entire bevel and edge are in focus. Very cool.
The top of the bevel is exposed well, but the edge is over exposed with blown out highlights. With exposure bracketing, one exposure is taken so the top of the bevel is properly exposed, then another (or more) with reduced lighting (exposure) so the edge is not blown out. The images are combined so the entire bevel and edge are properly exposed. Combine that with a polarizer and it should be able to make very excellent images to shiny steel surfaces.

They also have cool adjustable frames and other accessories.
I want one! The only issue is that they are expensive.
For a scope and stand it can cost $1,000.00 - $1,400.00.Sadly I don’t have a Dino-Lite so I can’t speak to how reliably this stuff works in practice, but I’ve got to hand it to
Dino-Lite for a feature set that directly addresses the major problems of USB scopes.

Mr. Cyrano, could you please post some example images of the automatic 5 stack focus stacking and exposure bracketing? I’d love to see some actual examples from a forum member.

Here's another cool video showing what this thing can do.
If anyone wants to buy me one I'll be very grateful.

Just one, Grepper? The longer we know you the more reasonable your demands become.
RE: Dino-Lite USB scopes - grepper - 07-13-2018
Do I detect a hint of sarcasm here? Has your heart become so callous, bereft of pity, and barren of compassion as to not feel the tug of poor Grepper’s pain whose plight is to grovel, devoid of even the most basic necessities in life of a Dino-Lite AM73915MZT with RK-10 stand and optional X/Y positioning arm and is left with only a basic USB microscope with which to eek out microscopy for the BESS Exchange?
The situation grows more desperate by the day. So just call. Call the number at the bottom of the screen and send poor Grepper a your gift of a Dino-Lite AM73915MZT with RK-10 stand and optional X/Y positioning arm and you will receive free a beautiful 109 piece Chef’s knife set that never needs sharpening! Call within the next 10 minutes and get free shipping too!!!
But wait! That’s not all! You will also receive a printable Gold Star of Generosity Award that you can print, frame and hang on your wall to proudly display and show all your friends how much you really care.

You go grepper, you go!
I feel compelled-ish. Okay, not so much.
RE: Dino-Lite USB scopes - Bud - 07-14-2018
I'm sitting here with tears running down my cheeks Mr. Grepper and I'd like to help you out. Make that printable Gold star a 24 caret one about a 1/4 inch thick and the size of a dinner plate and a new microscope will be yours.

In my experience, the EDOF feature works well, as one can configure the number of exposures (and thus DoF) to be captured.
The EDR is less sophisticated, and always captures 3 exposures whose difference from nominal exposure cannot be configured. For specular subjects like knife edges, the automatic exposure range is not always sufficient.

Those are really great pictures Cyrano! If you keep it up you're going to cost us $1300.00 or thereabouts.
RE: Dino-Lite USB scopes - Cyrano - 07-22-2018
As with focus stacking, Extended Dynamic Range (known in the photography world as High Dynamic Range, or HDR) can be done manually using third-party software. This HDR composite was created from 7 manual exposures combined using PhotoMatix, the doyenne of HDR imaging software for desktop computers:

RE: Dino-Lite USB scopes - grepper - 07-22-2018
Thanks for posting those. When the last image is zoomed in the roll is very clearly visible. Great images. The roll would have been much more clearly visible at a higher magnification, but I understand that showing the roll was not your goal in those particular images. That combination of EDOF and EDR rocks! Very cool indeed.
I thought EDR was an optional automatic function with the Dino-Lite Edge series as shown in this video starting @ 1:20
