If you have cropped they with the same ratio in LR, then you should have the same ratio in Pixels in the EXIF data. If you are using windows, go to File explorer and use view mode "details". Add a column of Dimensions and you will now have a column of the pictures dimensions. Sort on that column.

You make a very important point regarding access authority. I will restate in another way in the hope it will be helpful to others reading this. If you always log in as a regular user and NOT an admin user, it will offer you another level of protection. If you are not logged in as an admin user, the system will restrict your access. This means that if you accidentally try to run some program ( or are hacked) it may stop the program from running . Not always, but sometimes. As was correctly stated, most user applications, such as Topaz or Photoshop do NOT need administrator access rights to run, so there should be no need to run them from a user id with Admin access.

I often log in with a user ID that has admin rights, because I often run programs that require elevated access rights. But the rest of my family ONLY logs in with standard user access because it results in more protection.

As for the comment that it is "Windows not Topaz". I think that is likely, but until Topaz figures it out, we will not know for sure. Yes, everyone is running with the same Topaz code, but is the issue because some users have a Windows configuration issue? or is it because Topaz code is incompatible with some Windows update or code that is not on every widows install ? ( windows is often different on different installs).

I do have one easy thing (I just thought of) for TheShoe to try. Often, a user profile can get corrupted and some things do not work properly. To test this, create a new user on your computer. log on with that user and see if you have the same issue.

yes, I agree with you. Only certain (usually system analysis) Apps should require Admin privileges. The Windows security architecture does have documentation to be found, but it is often confusing or incorrect. I often find things that do not work as described and have bugs. It is an architecture that would make Rube Goldberg proud. Way too (unnecessarily) complicated to be easily supported. Hopefully Topaz tech support will find a solution. I will be interested in your progress. Please post it if you have time. Good luck.

For many program/application installs you are required to be logged in as an Admin, but that would not have anything to do with how the application is running after a successful install. If Topaz allows you to install it if you are not an Admin (IDK, I was an admin when I installed my copy), then it should work ok.
The option to select "all users" also should not have any impact. All that "should" do is install the app on the desktop of every user. If it is just installed on the user you select, and log on with another uid/pw, then they will not be able to run it while logged in with that other UID and probably they will not even be able to see the app when logged in with the other UID.
Just a guess, but do you have a password on your Admin ID? when you are logged in as a non admin user and try to run any app that requires admin authority, you will get a screen that says you need to be an admin and asks for a password. But, if the admin UID has no password, you will probably see the "continue" screen that you describe. Essentially this is a warning that you are running something with elevated access rights and if you are not careful, you could do something that hurts your computer. If you confirm that this is the case, I would strongly suggest you add a password to your admin UID, even if you are the only one to use your computer. It is good/safe practice to log on with a standard user and not an Admin. This protects you from many ways you might corrupt the computer by accident. Most user applications do not require admin access to run. Hope this is helpful.

you misunderstood my suggestion. I was not saying that link was the solution, I was trying to say you need to do your own research and that link was an example of thr type of info you could find. I did another search and here is another example of something I found from several years ago. I am not sure but it seems to be very similar to your issue, but from 2017 & with other apps. This would seem to support that it is a Windows issue or perhaps a Topaz config issue, but probably caused by a Windows update or bug.Could be the same windows bug from 2017, or a new one (they are "good" at that). Anyway, a I suggested, depending upon your Windows technical skills, you may find a quicker solution by doing your own research.
I have no experience with Topaz tech support, but I have interacted with several major software support companies in the past year, and have found that I am mostly dealing with help desk people or people that think they are technical, but actually have very weak skills. I would not assume that the people you are talking with at Topaz are very skilled. (my apologizes to Topaz if I am wrong- It is a very good product)
BTW, I have Topaz, the UserID I most often use has Admin rights, but I do not need to run Topaz as an admin to get it to work. This means that I cannot try to figure out your issue, or I would, sorry.

I would like to confirm that the Topaz people definitely said it was a Topaz issue and not a Windows issue? I am knowledgeable about the Windows O/S. It really sounds like a windows issue to me. It is not unusual for a Microsoft update to mess up access rights. I suggest doing a search to see if there are any suggested fixes. Here is an example link of some possible fixes, but most will require you to be comfortable with changing windows System information, so I am not sure how useful it is. https://superuser.com/questions/171917/force-a-program-to-run-without-administrator-privileges-or-uac. If it is a Topaz issue, they really should be able to tell you why. It may be easier to just create another userid that has admin access rights and log on with that ID when you want to use Topaz.

Yes, good, that turned out to be a solution. You need 2 products (in Windows) installed. ImageMagic and LR/Mogrify 2 as a plugin to Lightroom that essentially adds some additional options to the LR 'Export" page. At first, looking at the online descriptions of it, I thought it had the same limits as other products. The online samples showed a very limited of EXIF data selections in the 'drop down'. But I decided to install it and see if there were other items. It turns out they also have quite a few IPTC fields, which have all the fields I really want such as Title & Caption. Thanks for the solution.

Yes, I agree. I did look at several solutions that will allow you to select a few of the EXIF fields. All of them just had a limited number of fields. From a programming pov, why not code for all or most of the fields. All of the solutions I looked at had a very poor selection of EXIF data. Most did allow multiple fields to be selected. But, most of the fields you could display, I can see no reason to ever put on a photo.

I do not understand your suggestion.

Suggestions for a LR plugin or stand alone software product, please:
I am using LR Classic (current version on desktop). I would like to have the ability to apply a watermark to the photo with any of the EXIF data when I export to a JPEG. The fields I most likely want to use are the (LR names) "Label", "Title","Caption" and perhaps "GPS" fields. It would be a plus if I could choose any of the EXIF data fields.

I mostly just want the ability to have on my photos a description of where/what the photo is. A watermark at the bottom works fine. I know you can add this data thru the print option, but that puts the info outside of the picture. I want it on the picture. I display photos on a photo screen and it is nice for viewers able to see what/where they are from.
I have found quite a few products/add-ons that are available. Most of them have many functions to do additional changes to the exported JPEG (resize, change, fix etc). I do not need any of that, I just want to put info on the photo at the bottom. Any suggestions are appreciated.

1. Consider a laptop with a smaller screen, but with the same high end CPU & video card. The smaller screen should save you money and have the added advantage of easier portability (if that is a plus for you). It is very easy and affordable to later add an external monitor. This also gives you far more screen space for your photo editing.
2. Do not just look at specifications. Make sure the laptop has adequate cooling, both internal and by adding a "cooling stand". Laptops all have heating issues due to their small size and therefore limited space for fans. This means that they can easily overheat and that will result in the CPU being slowed down to protect it.
3. Puget Systems does some real great evaluations on computer systems specifically for Photoshop. I strongly recommend you look at their site. www.pugetsystems.com
4. As for your software conversion, you should list all of the software that you want to convert because the advice really depends upon what software you are converting and you will get more useful info.

Yes, exactly. The term "Professional" indicates nothing about competency. I am not sure why people on this site find it necessary to insult people, rather than just try and assist and answer a reasonable question.

Yes the parity is spread among drives. I was describing the logical allocation of the data storage, not the physical. Data and parity bits are not just on one drive. Raid 5 uses "disk striping". That means that for each "stripe" data is on all but one physical disk. The remaining disk has parity information. The next stripe alters that location of the parity information. This means that logically not physically, a full disk is taken up by the parity information.
The reason that you are seeing 43 TB and NOT 50 TB (5x10) is because a 10 TB disk does not give you 10 TB of data storage. Storage will be decreased depending on how the disk is formatted. Directory and other information (not counted in available data storage calcs) will also take up measurable space.

Small correction. In your example, Raid 5 would use 4/5 of the drives for data, and 1/5 for a parity bit. That means about 20GB of storage
