MDM Posted April 23, 2021 Share Posted April 23, 2021 (edited) 7 hours ago, Betty LaRue said: Thanks, guys. I understand more. But neither of you clearly answered my question do the folders on my desktop directly affect the RAM? Are those folders, even though they aren’t open, using RAM? Or is the RAM only being engaged by what I actually have open, such as Internet, PS, Bridge and LR? I await enlightenment. Seeing as Mark was reluctant to take the bait, I decided to run a little experiment in the background while watching footie on the TV. I copied around 18,000 full size JPEG images in 35 folders from an external drive onto the desktop of my Mac keeping them in the folders and used Activity Monitor to check RAM usage by the Finder. Here are the results (of the experiment, not the footie). 1. If the images are in the folders and the folders are not opened then no RAM is used. (That answers Betty's question for once and for all). 2. If a folder is opened then the RAM usage by the FInder instantly increases. Closing the folder does not release the RAM. However, the amount used is very small (about 20-30MB). 3. Opening all 35 folders at once led to a jump in RAM usage of about 400MB which is not released when the folders are closed. Opening one file in Photoshop and doing nothing uses about 1250MB of RAM. Doing a few operations increases Photoshop RAM usage significantly as Photoshop keeps everything in RAM. 4. Keeping image files straight on the desktop not in folders uses RAM just the same as opening folders. 5. Keeping the big pile of images into the Documents folder is the same as keeping them in folders on the desktop. Opening them uses RAM but leaving them closed uses none. 6. Restarting the computer releases the RAM and the same increases in RAM usage are seen when opening folders, implying that nothing is cached and it is all held in RAM. To reiterate, the key point is that if the images are in folders and the folders are not opened then no RAM is used. Presumably the MacWorld article mentioned by Mark is referring to keeping images outside of folders on the desktop. You would have to have hundreds of thousands of loose images on the desktop to make any significant difference to RAM usage but that would be some messy computer.

You would have to have hundreds of thousands of loose images on the desktop to make any significant difference to RAM usage but that would be some messy computer. I am educated now. This is something I’ve wondered about for years, and I never seemed to find the answer. I find it very interesting that loose images on the desktop uses RAM like an open folder. I don’t do that. It’s like RAM has been coded to ignore folders until they are open or have been opened. Another puzzler. I opened some images from 2007 and worked on a few in ACR/PS. I found that some of the sliders were different from what we have today. Most were the same, but there was a difference in the luminance slider, it harked back to being called “recovery.” Considered I opened today’s ACR/PS, I can’t grasp that. I’ve noticed it before while working on older images. Would it happen because the image had been opened before in the older program? There were some images I have saved the Tiff beside the RAW. But never uploaded, because they didn’t stand up to upsizing. I opened the RAWs again and developed it from scratch, but still, it had been through the older program. Now you and Mark have something new to figure out. 😂 But really, you don’t have to. I’ve just been puzzling over it for a couple of weeks since going through old images.

It is the Process Version for Adobe Camera Raw. At the bottom of the Develop Panel in Lightroom and similar in ACR, it's in the Calibration Panel - Process. The current one is Version 5 but if you have an image that was processed in an older version it will give all the sliders for that instead. If you just change the Process Version to 5 then there is no need to process from scratch but it can be a good idea as the new version is way better and has far more features. To be clear as well, the amount of RAM used by open folders or files loose on the desktop is really negligible unless you have huge numbers of files. 20,000 files would use about 500MB is what I found. I should have done a screenshot as the desktop looked amazing but not something you would want to use. Edited April 23, 2021 by MDM Link to comment Share on other sites More sharing options...

I need to trade something in so I'll wait till the Apple store reopens. Liverpool will be where the government will be testing the passport licence idea. It seems to me that I had to get several jabs back in the '60s and '70s to visit certain countries. Apologies for not reading this entire thread about iMacs. If I may add my tuppenny-worth however, I had the same dilemma last year but it was my son who instantly told me I was crazy forking out for one. Instead, he said (he's not in IT but taught himself home-computing in his late teens, to a very respectable level and reads more than I do on latest trends), consider a Mac Mini and fill it with RAM. This I eventually did (although just 16GB) and I have to say I don't regret this. Also, I may have to temporarily move my office system for a short remote editing session later this year and can move a Mac Mini easier than an iMac, for it do the same job. Of course, by now, you may have reached a completely different conclusion so I hope it's working for you! Link to comment Share on other sites More sharing options...

Actually I can probably summarize the thread by saying that Eizo and BenQ monitors were of course recommended, as were just ordinary IPS monitors from the likes of Dell. In fact Ed was limited in terms of where he would be able to source one so that might have been one of the factors that nudged him towards the M1 Macbook. I remember that when the Mac Mini came out I was 'tasked' with the job of increasing the RAM. I actually had to go up to the village hardware store and buy a can opener.

Ah, well - I made sure they put the RAM in before shipping it as I suspected that would indeed be problematic. Mind you, there's a huge jump from the 16GB I purchased to the 32 which was prohibitive.

I ordered 2 16s and will do the replacements myself, which appears to be easy. So I’ll have 32GB. I won’t use the 8, since I read somewhere that the configuration doesn’t make it work better, maybe worse.

Betty I added the 2 x 16 of ram to the already installed 8gb so now 40gb ram and it seems fine though I expect it will also be fine with just the 2 x 16's.

EDIT - just re-read the Apple guidance for the 2020 27" iMac and it does say that for optimal performance DIMMS should have the same capacity so you are probably correct just installing the 2x16.

Yet there are things I don’t quite understand because my brain doesn’t work that way. It’s strange how our brains work. I can imagine interior design and picture in my mind just how it will look. The colors, the spatial aspects, all of that. It turns out exactly as expected. Yet I’m woeful with technology. Thanks, Michael. Happy to have you solidify what I planned.

Thinking I could maximise the memory, I tried that once and its behaviour was very erratic so immediately removed the older ones from the slots. Also, the brand of cards are important so do check which are best-suited to your Apple model/manufactured date. 1 Link to comment Share on other sites More sharing options...
Betty LaRue Posted April 27, 2021 Author Share Posted April 27, 2021 Received a notice this morning that my iMac has shipped. No FedEx delivery date yet. Now I have butterflies in my stomach about setting it up, how to get things on the old to the new. I need to get online and figure out the safest way. The things that scare me is when it is being setup, questions are asked with choices. Of course, it’s the technical ones that horrify me. I don’t understand those choices enough that I’m terrified of ignoring one, or making a wrong one. It’s not even here yet and I need a tranquilizer.

It is not difficult to set up a Mac and the key thing to remember is that nothing you do is necessarily permanent. You have a working Mac as it is so you have something to check against for settings. You have your images on an external drive so that is no problem at all. As I said ages back, I don't recommend doing the transfer thing that is offered. It is much quicker and easier to set up from scratch. You can transfer your Bridge templates and any other Lightroom or Photoshop presets easily if you have any. Besides Adobe CC, what apps do you use? Are you using Big Sur already? Link to comment Share on other sites More sharing options...

There are several I have never heard of so Allan is not the only one. You might find that some of those apps won't work as only 64bit apps work on Catalina and later. There is no need to worry at all about the Apple apps such as Garage Band and Facetime. CC you just download from Adobe. Make sure you install Lightroom Classic not the cloud version 😀. The rest you can try (Topaz is a download but I think you have old versions so I don't know if they will work). Nik Collection it probably depends on the version. You can probably check compatibility before you download. Nik is now owned by DxO. As far as settings go, the fact you have a working Mac makes this easy as you can just copy across or start completely fresh. Could be Adobe settings such as templates and presets, Safari favourites, email (very easy with gmail and some others).
