It was really the business model, a one time price and ongoing free upgrades on professional software. It's not a binary choice use an old version or pay for a subscription or even buy a version and pay to upgrade(usually at a discount once you paid full price the first time).
Arguably video is photography at a higher frame rate, if I shoot raw video my camera produces a sequence of dng files which can be individually processed in photoshop or lightroom (photoshop does have video editing built in, as well as tools for painting and drawing).
Video and photography use a lot of the same tools and perhaps arguably there are some tools that work better for example noise reduction can be done over a series of frames, the result of noise is different between frames so a comparison can be done which helps identify what is image and what is noise. You don't have that with a single frame but astro photographers can use similar techniques with stacked images. I digress.
One thing i haven't seen mentioned is adobe bridge, this has cataloging features as does lightroom but it is free, you can also use adobes dng converter free as well. Having a range of tools is a good thing.
Photoshop is a good general tool, a swiss army knife if you like, but most mechanics would use tools dedicated to the task in hand. I know gene for example uses photoshop but i know he has other software he uses as well because there are times when the other software is a better option. You can be open minded about the tools you use. It's kind of strange that people get so polarised about life in general, or even Canon/Nikon :)

The most recent software I bought is davinci resolve for $300 it used to cost $1000 it includes fairlight which used to sell for $25-30 thousand. Now each upgrade to davinci resolve has been free. Now they would like for you to buy hardware from them, their editing keyboard is $1000. It is professional software used in movies tv shows and tv stations. Mostly they want more skilled people which helps build their position in the industry. Oh and if you cant afford $300 there is a free version with most of the features of the studio version.
Other software i have bought include affinity photo designer and publisher. Each have been updated regularly for free.

in the meantime i bought astropad although the subscription version is better it lets you export part of your screen on a mac to the ipad and use the apple pencil to apply drawing effects.

Very few people have mentioned the real factor that makes a difference to a photograph and the clue is in the name photograph or painting with light.
It's the light that matters, above everything else, cameras can alter the limits of what lightwill work and it takes a photographer to work the light. But bad light will spoil pretty much every photograph.

If you get a color checker passport photographed in the same light, you should be able to make a camera profile and you would need to calibrate your monitor too. AS to what software to use, i will let other people address that.

With testdisk one of the best options is in the advanced menu which gives you the option of creating an imagefile. You do need a hard drive big enough to hold the image file, usually not a problem if the drive is relatively small. If it was a single 4 terabyte partition you would need a drive bigger than that. however mostly you will want to recover from smaller drives and as long as the file system of the drive you are saving too supports large files e.g ntfs or hfs+ or ext2,3,4 its not a problem.
It's good practice to make a second copy and place it somewhere safe along with the original drive. It's kind of tedious to create but it gives a complete snapshot of the drives entire contents including the 'empty' space. Once the image is made.
Testdisk image.dd will then allow you to start the recovery on the disk image safe in the knowledge you have a backup.

Create a separate partition for /home. In case of an OS failure, boot from an install disk and replace the OS but save the original /home. I backup monthly and put it in a safe deposit box. In addition I use timeshift to recover if necessary.
With my nas(androidtv) there is very little in home, essentially it backsup itunes and it backs up lightroom every other hour to an external usb hard drive. It's quite a good system with 1 negative the ethernet port is only 100mbs not 1000mbs it's usb ports are only USB2 which has a max of 480mbs this is why its the backup nas since the other can run at 1000mbs.
Which has me thinking about improving networking...

or testdisk,
If the missing files are overwritten then they are not recoverable, testdisk is an awesome program.
Make an image file of your card within testdisk say myimage.img you can use C to select all files and folders and select a folder say on your desktop and then wait while it finds every file and reminant on the image of your drive.

I figured out how to mount the ext4 partition on a mac.
https://www.maketecheasier.com/mount-access-ext4-partition-mac/
It took an extra step double click the img file which mounts the drive but osx doesn't show the partition
however using diskutil -list showed it as a disk
/dev/disk1 (disk image):
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme +15.8 GB disk1
1: Windows_FAT_16 BOOT 134.2 MB disk1s1
2: Linux 15.5 GB disk1s2
then
sudo ext4fuse /dev/disk1s2 ~/tmp/MY_DISK_PARTITION -o allow_other
and navigating to
~/tmp/MY_DISK_PARTITION
gave me the partition in finder, it wasn't quite perfect as i found 2 videos on the desktop of the image one played the other i had no access to so i used testdisk to copy that to the macs desktop and then it played.
mounting the disk wasn't really necessary as i had as much access as i needed with testdisk

Trying to think of how to simplify things and its not that easy. A disk image is just a copy of every 1 and 0 on a disk regardless of it having meaning or not. disk recovery is a process of extracting the meaningfull stuff usually after the easy normal way got broken. Hard disk image files are commonly used on virtual machines but usually they are sparce, that is they only contain the files and not the 'empty' space. There is always something in the empty space be it random values or a deleted photo of aunt vera with a tree growing out the back of her head.
While testdisk is used primarily for file recovery you could use it to read files from a mac formatted disk using the hfs+ file system on a pc and copy them to the PC's hard disk. Even the deleted files from it.
There is no difference in the functions offered by TestDisk and PhotoRec when working on a copy instead of the original media. In example, TestDisk Advanced menu can be used to list and copy the files from FAT, NTFS and ext2/ext3/ext4 partitions or PhotoRec to carve data from damaged filesystem.
If the filesystem isn't damaged (or too damaged), it's also possible to access the content using native Linux or Mac OS X commands:
Linux
mount -o loop,ro image.dd directory
Osx
rename image.dd to image.img or image.dmg and double-click on the file.
I just checked my disk image from my nas is in 2 partitions the first partition is fat and osx can mount that but the 2nd is linux ext4 and it can't read that. Even so thats impressive :)
The limitation there is that the operating system has to be able to read the filesystem used on the image

Catalina breaks things, they have created a read only system partition, air display for example doesn't work because it can't install a driver. Anything 32bit will not work either. You don't have to install on your main drive, which is probably a good thing.

Testdisk and photorec have to be the best recovery software out there. It is completely free runs on Linux , Windows and OSX. It reads pretty much every file system going. Not only does it recover files but it can create a bit for bit image file of the problematic disk.
I run a nas based off an android tv box , the operating system is debian linux and on monday the electricity went out and it corrupted the microsd card that the operating system runs on. It wouldnt boot up.
The first thing I did was make an image of the disk using testdisk and then duplicated that file as a backup.
I made a new disk with a more modern version of the operating system but there are a lot of customisations that i've made over the years, it's main job has been backing up my main nas every hour for the past three years. The data itself is fine but naturally i want to get up and running again.
The disk image has been a life saver as i have been able to run testdisk mounting the image and pick up the configuration files from my old operating system. This i have been doing on my mac which doesn't even read the file system of the card. I'm just browsing through the folders and choosing which files i need and copying thenm to my desktop. The only thing it doesnt do is write the image back to a card, although if you have an operating system that understands the file system you could actually recover back to another card, or drive. Although there are a few programs that can do that for you such as etcher or dd.
I've used test disk for years for recovering data but not for an operating system. linux can mount disk images but you need to create a loop device assign it a mount point ... where as
testdisk myimage.img takes care of that technical stuff for you.
I can't recommend this highly enough.

Its worth baring in mind that you can easily run different versions of OSX via USB, firewire esata and thunderbolt. or even target disk mode.
I'm running el capitan on the internal drive of my macbook pro I have catalina on an SSD connected via esata and thunderbolt.
If you google dosdude and catalina say you can find he has apps that can create installers on unsupported macs, although catalina needs a metal compatible graphics card. integrated that means ivy bridge or newer but for mac pros you can find compatible graphics cards.

Hi there is a new release of affinity photo 1.73 as well as designer and publisher.
This release includes enhanced support for 'sidecar' in catalina. However not all macs will support sidecar.
A lot of intel procesors feature hardware video encoders known as quick sync. Ivybridge processors had h264 encoding. Apple used this for Airplay so you could extend your desktop to say an apple TV or mirror your desktop display. Basically your desktop and windows were composited to a h264 video stream which was decoded on the recieving device. Best of all it was essentially free as it didn't use gpu or cpu cycles for doing this as it was a seperate bit of silicon on the CPU die.
Airparrot was a third party solution which did the same thing only with a software encoder.
Duet display works similarly but uses the iPad as a screen. And then Apple made Sidecar. Its fairly similar in practice to duet but it uses quick sync for hardware encoding to h265 video. This has about twice the compression of h264 which makes it possible to update faster and support higher resolutions.
The problem for older macs is the CPU doesn't support h265 hardware encoding, it needs a skylake processor as a minimum.
On the plus side duet still works on catalina and the maximise button has been extended to as well as maximise it can set an app to half screen verically split or send the app to another screen , e.g iPad. So far duet isn't supporting the new sidebar in sidecar but you can have the macs touchbar , even if you don't have it on your mac.
What makes this of interest really is apple pencil which makes it quite easy to work with dodging and burning directly on the iPad but using the desktop app. The pencil works on iPads from 2018 as well as the iPad Pro
I hope this has been of interest.
