I bought the YN600ext-rt for camera attached use, in place of the built-in flash, as a master; for my Canon 430 EXII as a slave. I believe that this uses optical link, which was addressed in the response I quoted.

To answer your question: Yes, I am referring only to the optical link. I can't speak to the radio link, but this is from a response earlier in this thread.

Here is a reply from Yongnuo.

Dear User,

Thanks for contacting us!
We are sorry to tell you that YN600EX-RT doesn't support optical wireless function as master, it can only be used as a slave flash when using optical wireless function.
Thank you very much for your great support for YONGNUO products! If you have any other questions, please feel free to contact us again.

Best regards,

YONGNUO

Yongnuo can not be used as a master for remote slaves like the Canon can.

I am using a Canon Pixma Pro-100 printer and would like to try some monochrome printing.
I would expect any photo paper to give acceptable, or even excellent b&w prints. Is there a recommended paper for outstanding b&w prints?

I'm not sure what you're thinking, but here is my best guess.

Use the eyepiece viewfinder instead of live view.
I wanted the tripod as stable as possible. If the tripod is high enough for me to be standing while using the viewfinder, it would not be as stable as it would be at the short height that I used.

Let the lens auto focus, instead of focusing manually with live view.
This may work, but I wasn't pleased with how well it choose the subject instead of the background. I could set it for a single focus point.
I would need to use the viewfinder to be sure, which was at an awkward height.
I can enlarge the live view x5 or x10 for more exact manual focusing.

Use mirror lockup to reduce camera shake instead of live view.
I wanted to use IR remote shutter release to reduce camera shake. The Cannon 70D normally has a 2 second delay. With live view, there is no delay. This may also be true with mirror lockup, and is worth investigating.

My goal was to use a setup that gave the sharpest image possible rather than to just get a picture of some seagulls.
I'm planning to use different settings (exposure, ISO, etc.) to see which I like best. I may try auto focus using the eyepiece.
This seems to me to be real world usage. I can switch eyepiece/live view easily.
If you have different or additional advice or considerations, I'm eager to learn.

Contemporary.

Live view gave me the ability to have the camera at a level that would be difficult to use the eyepiece viewfinder. Also, I was able to enlarge the image for better focus. It also locked up the mirror to prevent vibration.

No question, just sharing information concerning the lens.

This is more about the lens, it's performance, and the setup than the image.

Distance was about 75 feet. Tripod was of moderate quality, column in the lowered position. One leg extension was used, not both. Focus was manual, in live view. Shutter release was with a remote IR trigger, using 2 second timer mode. The release was immediate, since the mirror was already locked up due to being in live view mode.

These were taken in mid to late afternoon, in full sun, at 600 mm, f/8, ISO 800, 1/500 sec. with a Canon EOS 70D, 1.6 crop factor.

Original was raw, 5496 x 3670, cropped to 3703 x 2862. Rawdigger reports 0.5% red, 1.0% green, 0.6% blue, and 1.0% green2 over exposure; no under exposure.

Any and all comments are welcome.

I realize that this is not a direct answer to your question, but I'll throw in a thought that might help.

The reliability of your backup drives doesn't have any affect on the security of your data. You should have a plan to recover from a drive failure. No matter how reliable the drive, it's not 100% reliable.

The more reliable the drive, the less often you will need to recover your data, but this is the only benefit of a more reliable drive.

Being lazy wasn’t the reason for my post. I didn’t realize how good a resource Google was for this type of question. If I had, it would be easier to use Google instead of crafting a comprehensive post, and I wouldn’t have been castigated for seemingly not really trying to answer my own question.

Perhaps my post should have been “Where can I find information concerning…”, rather than “how do I ….” In that case, your second response containing three links to resources would have been more appropriate. I noticed that none of these was a manual. Even the response of "Go to Google: Type in "image order in Lightroom grid view" would of been all I needed.

I have spent several hours reading on line tutorials on Lightroom. None of them addresses this problem. It isn’t that I didn’t want to expend any energy to find my own answer, it's just that I didn’t know how.

I’d like to point out that the title of my post was clear and informative, rather than a general “I need help”. I understand that is one of your pet peeves. Also, I described the problem clearly and completely. I've tried to be a good forum member.

Second, I wasn’t looking for a long and involved tutorial. LarryFG’s response was a single line.

I have read Scott Kelby's Lightroom CC from cover to cover, more than once. This question is not covered. I also spent a fair amount of time trying to solve this on my own.

It seemed to be a reasonable next step to post the question on this forum. I got a polite and accurate response. Then I got your response. You didn't suggest a manual or other source. You can do better!

That's exactly what I needed. Thanks.

I have imported several files from a folder into Lightroom. Some were imported as a group first, then others were imported later. They are all named the same, except that each has a different number suffix.

When I display them using Windows Explorer, They display in proper order by filename (numerical suffix).

When I display them in the Library module, Grid or Loupe, most of them are in order by filename. However, a couple are out of order. They are not at the beginning or end, but just a few positions from where they should be.

Can anyone tell me how to get them in order by filename?
