Hi all,

I have been using cs6 fine for months, and all of a sudden I have encountered a strange problem. Basically I open up an image in camera raw, I do my adjustments as normal, then open into cs6 and the image is just noisy and grainy as hell!!! I save image as a jpeg and all is fine? I save image as tiff and all is fine. I re open the images back into cs6 and again noisy and grainy as hell?????

I'm going to assume that maybe this is a computer processing issue as my comp is very old and of late even doing a standard black and white conversion is throwing up the error message 'Not enough RAM' Are these two linked?

Any help appreciated

Matt
 
Does sound like a memory problem
How much memory is being reported by the system. Is it the same as you have installed
Also how much free disk space do you have. Typically if there isn't enough RAM memory then the system will use the disk as a temporary source of memory. Slows things down but keeps the system going. Limited disk space may cause this not to happen hence memory problems.
Does a reboot cure the problem
 
If your PC runs out of memory, it just pages to the hard drive as virtual RAM. If you run out of memory, the computer just slows down, it will not corrupt files in this way.

Can you post up an example of the noisy images to look at? A screen grab of Adobe Camera RAW would be useful as well.

Check the ACR save/export settings at the very bottom of the ACR screen.. it's in blue... click it... what does it say?

Not too sure from his description that the files are being corrupted but rather the displayed image. Would lack of memory cause problems with rendering the image on screen? Really don't know enough about his to be certain. Where's neil_g when you need him :)
 
id be inclined to agree with pookey on this, i cant see a lack of RAM causing extra grain in a photo.

can the OP post some examples online for us to see?

e: hi by the way :D
 
Is it possible that CS6 is opening the preview .jpg file embedded in the RAW file instead of the RAW file itself?

No. If VRAM was in short supply, ALL images displayed would be effected, and even then, it will be a performace issue as a result, not quality.


There's no way this is caused by low memory, sorry. This is a CS6/file/export settings issue.
 
As RAWs are normally a smaller size than the TIFF and the TIFF is opening ok could; as Ancient_Mariner suggests it be CS6 'doing' something with te RAW file? do you have another RAW program you can open the original in? that might confirm whether the RAW file is corrupted, or at least rule out that possibility.

Download the 30 day trial of Lightroom, possibly use the RAW software that came with the camera
 
Thanks for all input guys, just got back from Greece, once I get chance I will reply in more detail and get some screen shots up.

Welcome back Matt,

Does all the images do the same thing noisy etc... this could be a RAM/Hard drive space issue if it is all images in CS6 as it could be loading not the full image. Though generally the outcome of image not being fully loaded is blurred image (eg scaled up thumbnail) rather than noise.

Likely hood is some sharpening or exposure comp in export.
 
Hi all,

So today after doing some research I decided to try a few things.

Firstly I loaded some old raw and old jpegs from previous work where I know I never had this problem. Once opened in cs6 they displayed the same grain/noisy effect.? Strange.

So I went out and bought 2 new 1tb hard drives, I used 1 for the scratch disks and used the other as another back up drive(never have enough backups IMO)

After doing this I defragged everything.

And hey presto all is now displaying correctly.

So I'm guessing the defrag freed up RAM, I also changed the virtual memory amount and selected the spare 1tb hard drive as the paging directory.

Not sure what exactly worked but something has.

Thanks for all input.

@mattd85

Defragging will not free up RAM. It just increases drive read/write speed by taking fractured files, and putting them all back together again in a more contiguous form. Defragging does not erase anything, and does not free up space.

Increasing virtual RAM will help system performance, but in all likelihood, the scratch disk you were using prior to this was too full and when your system ran out of RAM, it didn't have enough disk space to page to.


Having a back up drive in the same computer as the drive you are backing up is a bad idea. If anyone steals your computer, they've also stolen your back up.

Thanks @Pookeyhead , this back up drive is backed up and then disconnected and stored safely away, leaving the original plus an empty one attached to the computer.

I was looking at a 4tb wireless one though ;)
 
@mattd85

Ok... so these two new 1TB drives you've bought.... they're USB?

Unless you have USB 3.0, then you're limited to 12MB/sec speeds... and a scratch disk needs to be as fast as possible. Speedwise, a USB2.0 external drive as a scratch disk will probably be slowing the system down more than helping it. It's better than having NO free disk space, though. Why an external disk for a scratch disk? You using a laptop?

If it's USB 3.0, then you're fine.
