I think ... my computer is dead

It crashed while focus stacking 10 photos in photoshop.
Trying to reboot it the hard way just for it to do something, but is it normal for photoshop to just freeze like this when you are focus stacking?

I am trying something new and I think I killed it

Windows 32 bit or 64? And how much ram do you have?
04/11/2015 11:17:18 PM · #3
64 and 6GB

I was able to delete a lot of photos off too and that was about a few GB.. still slow though.

I've never focus stacked before so I'm not sure, but you may try adjusting how much ram PS is using. I'm sure others here have more expertise than me however.

Photoshop is not the problem for focus stacking. I do this regularly with 20 to 30 pictures. (did it even with more)
When focus stacking you need a lot of processor power (CPU) Your computer should either be a 6 or 8 core processor,
At least 8GB Ram .

That is what I was afraid of..

It did great with less than 5 photos but 10 seemed to have crashed everything LOL

That makes so much sense now, thank you guys

A minimum of 6 to 8 cores sounds excessive for stacking just 10 photos. I do agree that 8GB is probably the minimum now-a-days for anyone doing any kind of post processing. With that said, my gut says you should still be able to do it with 6GB, if you're patient.

When it "crashed", how long did you wait before you hard booted it? How long did it take to stack 5? Was Photoshop the only program up while you were stacking?

No I had lightroom up as well, I usually run both of them together because I have them interlaced to go back and forth with the bridge, to do 5 it takes 3-5 minutes and there is a really bad lag in-between times.
It took me almost an hr just to hard boot and to get things unfrozen. I had to remove the battery from the laptop twice.

Was the laptop hot?

No, and that was the weird thing.

But you could hear the processor running harder at faster speeds

Yeah, that's weird. If it were working its tail off, I would imagine it would be getting warm. Have you tried doing 10 again or scared because of what happened? I feel like I might not have tried again myself, and just hugged the poor thing and thanked it for trying, heh.

I'm curious, if 5 images takes 3-5 minutes, how long should 10 take? I would imagine it's not a straight "3-5 x 2", but instead some kind of exponential value?
04/12/2015 04:44:09 AM · #12
Hahhha no I haven't tried it yet because I have to get things backed up beforw it does croak for good.

Just a death warning I think...it does good otherwise

when i am trying to get an idea of an image's potential, i'll export workable files from lightroom, rather than work with the full-size, original files. (i am typically making panoramics.)

8" @200ppi produces files between .7MB and 1.3MB (usually), which in and of themselves produce nice 8x10/12 prints. these files are good enough for me to get a sense of what i can expect. sometimes, i don't even need to go larger.

i've never played with focus stacking, but i would imagine you could probably do proof-of-concept work with smaller files, before having to commit to going all-in with the full-size files.

good luck!

3-5 min is a loonnngg time for an operation on your computer. You definitely seem to be hitting the limits of what your laptop is capable of. You should try shutting down all other apps before attempting something like this again, as your other apps are consuming the same resources that PS will need to do the processing. You are likely CPU and/or memory bound for what you are trying to do. It may not be possible to do it on your current machine, or it may work but take a very long time. You can run the Task Manager to monitor CPU and memory usage while processing, it will give you an idea as to your resource usage, as well as possibly let you know if the machine is not in fact hung, but extremely busy.

If you could "hear" the processor working, you've got bigger problems than photoshop ;) I'm assuming you heard the hard drive grinding away.

It could be a fan too.

I am techy but not that techy..

Its the sound that the lappy makes when programs are running...

Whoa! Are you perhaps a fan of Homestarrunner?

I don't watch tv, no clue what that is, so I will have to google
