Minimum amount of free storage space required for Photoshop for iPad to run well

Hi,

 

Please can you tell me if there is a minimum amount of free storage space required for Photoshop for iPad to run well?

 

I was considering purchasing an iPad Pro with 256GB storage, or an iPad Pro with 512GB storage and I wondered if the additional space offered by the 512GB version would help Photoshop to run more smoothly?

 

ie does Photoshop for iPad require free scratch space as the desktop version does?

 

I've had a look at the minimum recommended system requirements for Photoshop for iPad at the link below, but don't see details of this. https://helpx.adobe.com/uk/photoshop/system-requirements-ios.html

 

Thanks for your time and help.

 

Kind regards,

 

John

I have it running fine on a 64GB iPad.

Thanks JohanElzenga,

 

Can I ask please how you find Photoshop for iPad when working on very high resolution images?

 

I'll be working on a Photoshop image which will be around 100cm x 100cm at 300ppi (approximately 39.5 inches x 39.5 inches at 300ppi) with - at a guess - around 50-100 layers.

 

In your experience, how do you think Photoshop for iPad would handle a large image with a high resolution like this?

 

Would I experience very noticeable slow down on an iPad Pro do you think?

 

And would 256GB storage v 512GB storage make any difference where a large, high resolution image is involved?

 

 Thanks again for your time.

 

Kind regards,

 

John

I never tried it on such large files, but I wonder if your math is correct. An image of 39.5 x 39.5 inch is so large, that there is absolutely no need to have a resolution of 300 ppi. Such large photos are usually printed at around 100 ppi or even less.

 

Anyway, the storage capacity of an iPad is not the same as the RAM of the iPad. It’s like the hard disk of a desktop computer. I don’t think that a larger capacity will do much for the speed of the iPad.

It works awesomely fast. Local storage is useless for you, Photoshop on iPad is online storage only. You can do offline stuff but it’s tedious.

Thanks for this too Konstantin - I had assumed you could open and run Photoshop files both from the cloud and locally from the iPad’s storage.

 

Although from the link below it seems Photoshop files can be moved from the cloud to local storage.

 

But I get the impression it’s not quite as straight forward as being able to ‘open, edit, save’ locally etc as one would on a laptop or desktop and not use the cloud atall.

Saving your document is only available to the Cloud, Adobe currently prevents you from saving locally. This means that you can not save and quickly see all your documents in one place locally, inside the Photoshop app.
 
Aldo you can’t save, you can Export your document. But you can see how these differ. Exporting will export the document outside of Photoshop into the Files app — but id you want to go back and edit the image, you will have to Import it once again, and export it when you’re done, and it’s just all tedious. But the option is there.

Thanks again for getting back to me Johan.

 

The graphics I'm working on are to be printed on the base of three (vertically presented) skateboard decks.

 

I create one very large 100cm x 100cm artwork at 300ppi because this is the spec required by the commercial printer I work with. And he splits this large, flattened graphic across the three skateboard decks.

 

If I supply my 100cm x 100cm artwork at 100ppi, the printer will just email me and ask for it in 300ppi. In this situation, 300ppi is appropriate as the decks will be viewed both up close and also at a distance.

 

And yes I completely agree - the storage capacity of the iPad is not the same as the RAM of the iPad (6GB in the current iPad Pro) - the two are different things.

 

The desktop  / laptop version of Photoshop uses storage space to write temporary files to while you work on a Photoshop document - in the case of larger PSDs it's especially important to have a good amount of free storage space so that Photoshop can write temporary files to your hard drive or SSD if they don't fit within available RAM.

 

https://helpx.adobe.com/uk/photoshop/using/scratch-disks-preferences.html

 

This is referred to as a Scratch Disk within Photoshop's Preferences in the desktop version. And hence the reason you get messages saying 'Primary Scratch disk full' sometimes if your storage is almost full up and you try and open a large Photoshop file.

 

I wondered if Photoshop for iPad also works like this.

 

May I ask -

 

In Photoshop for iPad, is there a preference called 'Scratch Disks' ?

If there isn't, then possibly Photoshop for iPad works differently to Photoshop for laptop / desktop. 

 

Thanks again for your help.

 

John

Photoshop on iPad require 2GB of free disk space to run. There is no setting for scratch disks on the iPad version of Photoshop. An image of the size you describe with 100 layers will be around 33GB. Layer masks would increase the file size further.

I worked fine on 12,000 x 17,000 16-bit images with blazing performance on my 64GB 11” iPad Pro. Performance was jaw-dropping. The lack of features made me cancel the subscription two months after tho.

Thanks Konstantin, that's cool the performance was that good although I can understand you might want to cancel (perhaps temporarily) until the features are expanded. 

 

Have you tried Affinity Photo for iPad?

https://affinity.serif.com/en-gb/designer/ipad/

 

Seems like it might complement Photoshop for iPad well.

 

I'm really curious to try the touch versions of all of image editing software at the moment.

 

I'm intending to try Procreate as well although I realise it's function is very different to the above software.

Affinity KICKS ASS! the performance is awful on HUUUUGGEEEE image files (nothing like photoshop), but on normal files (40MP, 16-bit) it’s amazing. And the features are so good, and I LOVE designer!

 

The way Photoshop antialiases text on the iPad is simply horrifying. It’s literally like they’ve turned off anti-aliasing. 

 

 
People do remarkable things with this app, and it’s cross-compatible with Photoshop. It just lacks that lusty, german design polish that Photoshop has. The icons, Animations, and UI is just not as refined. Still my favorite app that makes my iPad WORTH IT!
 
 
 
The filters list is HUGE! I was so surprised to find such niche things like Frequency Separation in there. The performance of filters is blazing fast.
 
ProCreate is an app for drawing, it’s just NOT good for Photography. I have all of them, and ProCreate is really just like, I don’t know… A really really awesome drawing app, with “pro power-point design features”.
 
Yes, the design features are there, but it’s just like powerpoint. Not that powerful. But really neat. 
 
 
Apps like AlightMotion, LumaFusion, Affinity Photo and Affinity Designer made me ditch my Mac for 14 months now. And I never looked back.
 
The interactivity, and pure connection between me and my artwork is something NO graphic tablet on any PC can match. It’s just so intimate, so wonderful… Steve Jobs was right.
 
And Adobe is a slow pig in this game.

Here are some things I’ve made with Affinity Photo on iPad.
