Please be noted that your phone memory should show as a drive letter in your explorer, if not, you need to take out your memory card and connect using a card reader, or plug-in to card reader slot if there's any on your computer.

Indeed, disk formatting doesn't erase the files (until these are overwritten by other files). You still can recover samsung galaxy data with some tool. Here I recommend you Tenorshare Data Recovery. Few days ago, I also deleted all the photos in my samsung galaxy s3, thanks to this tool, I can get my photos back. I think it must can help you too.

Sure, you can.
Card Data Recovery is professional photo recovery software to recover deleted, lost, corrupted or formatted photos, videos, and auido files from various memory cards, such as, SDHC card, SD card, CF card, memory card, memory sticks, USB devices, digital cameras, hard drives, and zip drives.

The answer is YES if you take care. But it is not 100% sure as there are many factors affecting it. So please follow these steps:
-----------------------------------------------------------

First things first: DO NOT take any more photos with the memory card(within your Samsung phone) that you want to recover photos from. Take the card out of your phone and put it in a safe place. Because if you take any more files or save any data to your memory card, you may quite possibly ruin your chances of recovery.

Then Connect the card to your computer as it should appear as a "Removable Drive" or put the card in a card reader attached to your PC.

Next, if you are comfortable with using a PC then you can download a photo recovery utility that will recover your pictures with this software called Wondershare Photo Recovery (I once used this program bounded with some other software) from the following link(the program also recover videos and music files):

Photo Recovery for Windows (if you are running Windows OS)
Photo Recovery for Mac (for Apple Mac OS X)

Remember - Do NOT try & write anything back to your mobile phone(memory card) until you can recover the files safely!
