As a general rule buy fastest card your camera can effectively use for video. You would have to look at the manual for your camera to see what is recommended. But to buy a card faster than your camera can write to will just cost more without any benefit.

No, I was indicating that the fault does not lie with you. You mentioned that you had done a search before posting. I was saying that UHH search is very bad. Someone here said it only searches the Topic Titles - I do not know if that is true.

So I posted a way to search UHH using Google and these results WILL include the content in the whole topic, not just the Titles. [And this search format works for other sites also.]

I am sorry if it seemed I was critical in any way. I was just full of myself for having found that search "trick" and wanted to be helpful.

The search on UHH is not very effective. You can use Google to search the contents of any website using this format in the Google search:

site:somesite.com your search terms

Examples:

site:uglyhedgehog.com B&H tax lawsuit

site:uglyhedgehog.com tripod travel carbon fiber

I would buy a small external hard drive for backups. It will be by far cheaper per MB of drive space and far more reliable than a thumb drive. The only thing nice about thumb drives is they are small.

The photostick, and there are two companies making them with slightly different names, probably runs a small program that finds your photos on your hard drive and copies them to the otherwise ordinary thumb drive.

Yes, that is true, but there are other 32 bit software that will not run in Mojave and therefore this upgrade is not for everyone. Some of us do not do not need a 64 bit limited OS or the new feature "Dark Mode".

And Apple makes it easy to restore your last OS using the Time Machine backup that you did before the upgrade. Apple gave plenty of warnings about this upgrade's new "feature" (that is - it's 64 bit only limitation).

Interestingly, around the 16:44, in a non-answer to the posed question, Milton Friedman says the interviewer and Milton "know" that an aspirin every other day (or a baby aspirin every day) lowers the risk of heart attack.

Well, 20 years later, that is no longer the medical/scientific knowledge and is no longer recommended.


From the song Dodo by Dave Mathews

"Once upon a time
When the world was just a pancake
Fears would arise
That if you went too far, you'd fall

But with the
Passage of time
It all became more of a ball
We're as sure of that
As we all once were when the world was flat"


Knowledge is not belief and belief is not knowledge -- except on occasion.

Now we have seen photos of the Earth and know it is more like a ball than a pancake but some of us still believe it is a pancake!

I am curious, was there some enhancement in Catalina that you wanted?

Agreed, it is a shame that the taxpayer (and obviously the victim) end up paying for these mistakes by law enforcement personnel. It is fortunate for the photographer that the camera was not "mistaken" for a weapon. It might have ended much more tragically.

Law enforcement personnel need better training so that they know the law AND be required to face consequences when they make mistakes. Then they will have the knowledge and incentive to do their job legally.

Here is a case involving poorly trained officers killing a man after he was hit from behind by another car and did not "do the right thing" after the accident. He broke no laws but was still shot four times in the head:

For those who miss the heft of their full frame DSLR w/battery grip.

In the same way that you can focus "in front" of your subject or "past" your subject whenever it inside the range of focus of your lens/camera combination.

I am going to go out on a limb here. I "believe" that in the days before auto focus lenses were designed to stop at the infinity focus point. But because auto focus requires comparisons at different focus points to determine good focus the range of focus must extend beyond infinity for the comparison to work.

"Belief" is easy -- it requires no true knowledge.

Windows and OSX operating systems have converged to be very similar. The main difference in the two is in the hardware. Apple is the only maker for OSX systems and can command a higher price for the same performance. Adobe software ten years ago worked better on Macs but today the performance is at least as good on a well built Windows PC.

Since you are used to Windows I would choose a well built PC from Puget Systems. Apple does not even have a "real" high performance computer yet. It will be the new Mac Pro due in this fall and will be an awesome Mac but very pricey.

If you have access to a Mac you might try to open them with Preview (Apple's default image viewer). At work I have had occasions where Photoshop would not open an image (with a similar warning about the JPEG marker) and Preview would open them just fine. If you then just save the file from Preview it seems to fix the problem.
If you upload an example file maybe someone here can test this procedure on the file for you.

I have rethought my answer. I do not think it is something blocking the sensor. I think it must be a stuck constantly "on" pixel (the red one) on the sensor. When a dark colored item is scanned the red "on" pixel shows red and the other two colors do not show any color (green and blue from RGB). When a light object is scanned the other colors do contribute to the data and the result is probably still 100% red plus the addition of green and blue so the resulting color of the line is closer to the scanned object.
