Hope someone has a solution for this one: uploaded 1500 jpeg images to pc via firewire, noticed speed was usb2, cancelled upload restarted and folders appeared empty...checked the card (Sandisk Extreme IV 8 GB) and showed 2 boot file errors...it wouldn't read. Formatted card and used Sandisk Rescue Pro to recover files...got all 1500 back. Files occupy 7 GB on HD and are approx 5 MB each. Viewed files in Photoshop, looked good as thumbs, opened them randomly...all open as 56 k 120x160 low res??? On HD they are 5 MB each and should display as 3504x2336. Windows also displays them as 120x160...Does anyone know how to get these to open as high res images. Thanks

You can't open a low resolution image and recover a high resolution image. You can only down sample the image.

Just guessing here but maybe they are in one of the propietary raw formats that Digital cameras use I would look for software that matches the brand of camera they were taken with.

GIYF here's a start.

Otherwise maybe increase the default file size when you carve.

Hi dthstker I uderstand that I cannot get a high res image from low res image...this files on the HD are nominally high res...as shot...3504 x 2336...for reasons unknown the do not display that way...what I am seeking is a means of getting them to display the 5 MB of information that each contains...any ideas?

Hi Mike...thanks for the suggestion...I already have all the Canon Raw codecs loaded in Photoshop...these files were shot as Jpegs. They display as 120 x 160 in both Raw File Viewer and Photoshop and also in Windows. I'm really puzzled by this one.

Can you post one so we can have a look ? Or are they evidence / client confidential.

Maybe try a different carving tool like photo_rec for example.
