The only memory cards that have failed on me have been a couple of SanDisk MicroSDs. Still, I think I should play it safe and order replacements for my current SD cards. A couple of my cameras have two card slots, but if one of them fails, that leaves me with just one, and if that fails...

I have two SD cards from July 2022, but the others go back several years. Yes, they work, but how long will they continue working? I've heard too many stories about people taking hundreds of pictures and having them all disappear.

My skill level is a novice at best, but my brain is now a photographers brain. I find myself looking at every scene as if it were a photoraph. Flowers, insects, birds and wildlife. While looking at photographs I find myself thinking how I could repeat a similar shot. While driving the landscapes are a series of potential photos.
I am confined to a wheelchair so my perspective is a little different but my mind is that of a photographer maybe someday my skill level can match the shots in my brain.
Have a great day

I'm summarizing an article I found online - Digital tools that pro photographers like. This is from June of 2015, so the camera choices will be outdated.

Frank Doorho0f - “One of the things that I love to do is work with the modern-day solutions to see your images on your iPhone and iPad immediately."

Brendan Van Son - "For me, it's the smartphone. And, actually, it's quite funny but for the first 3 years I travelled, I didn't have a phone of any sorts with me. But, the rise of Instagram made me decide that I needed to jump on the smartphone bandwagon."

Jimmy Chin - “Being able to build an audience, personally curate images, share them with people around the world, get immediate feedback and have real time interactions between photographer and audience has hanged photography. The access to large audiences can be quite powerful.”

Jake Olson - “My most important tools are my camera, my laptop and Lightroom."

Peter Hurley - “ 'About Me' pages and people’s desire to formulate their own personal brand and establish their digital identity has changed the landscape of headshot photography. For years I mainly had actors coming in for headshots, now I have people from all walks of life.”

Jack Hollingsworth - “Right now the most valuable and treasured tool in my camera bag is my beloved iPhone 6 Plus."

Frederick Van Johnson - “Currently, I shoot with the Panasonic Lumix GH4. For my chosen genre, the fast, light and highly capable mirror-less cameras are ideally suited for being nimble, and "in the moment."

Gary Arndt - “My most important tools are my camera, my laptop and Lightroom. I have to take photos and process them, and I have to do it on the road.”

Jordan Loyd - “I recently picked up a Panasonic LX100. The advances made in this area of photography are incredible."

Eric Kim - “My favorite digital tool is my iPad, which allows me to blog in a minimalist format (with the iA writer pro application), helps me share my photos with other photographers to critique my images in the native Photos" app. Furthermore, I love the VSCO app on my smartphone which helps make my digital mobile images look like film.”

Let's say I have a bunch of pictures grouped together, more than show on the screen. I have to scroll down to see all of them. Is there a way that I can get a picture of the whole group, even though they don't all fit on the screen. Ctrl-- will reduce the size, but not enough for all of them to fit onto the monitor's screen. Basically, I'd like to take a hundred little images and combine them into one.

I can break the images up into groups and then join the groups to make one big picture, but I thought there might be a simpler way.

The new Point Color feature is absolutely incredible. If you (as I do) use the many color processing features of Lightroom in your post-processing, the Point Color feature is a game-changer. The granularity and precision it affords in color management is extraordinary.

A bit of a learning curve (but not as much as the new UI makes it seem), but well worth the effort. A good starting point is this YouTube video by Julieanne Kost (Everything You Need to Know About Point Color in Lightroom Classic): https://www.youtube.com/watch?v=Fzdg2ZXaKGo. Of course there are already many other videos on this feature, and many more to come no doubt.

You failed to mention which Topaz product you are asking about, Sharpen AI, DeNoise AI, Gigapixel AI or Photo AI (all 3). From my experience, these Topaz products are excellent at what the're intended, but are not a full post processing engine. I believe Topaz suggests you start in Topaz before doing other post processing. I have had best results by post processing in LR first then exporting to Topaz Photo AI for DeNoise and Sharpening (no denoise or sharpening in LR). I always start with RAW (to give the greatest post processing potential) unless I just need a quick snapshot for sharing or reference.
