raw images in photoshop CS6

[maryjojones]

Hello, I just used my new Canon EOS 7D Mark II last night for the first time, using the settings where the camera saves the images as raw and jpeg.  I have never shot raw images before and wanted to try it out.  I put the images on my MacBook Pro, like I always do, both jpeg and raws. I selected the images I wanted to edit and tried dragging and dropping them into photoshop like I always do.  When I did this, a different screen popped up, asking me to open, edit, close.... with editing functions on it.  I clicked open and put them into my normal editing area, edited them, and saved them.  They all went from ~15MB down to ~5MB and turned into JPEG.  I dont know why, but they also shrunk in file size when I put them into photoshop.  Can you help me figure out what I am doing wrong?

Raw images are inherently bigger. Depending on the content of the image, and the amount of compression chosen when you save the JPEG from Photoshop, 5 MB seems to be a reasonable size for the resulting image.

Check your camera settings, I think you are set to M-Raw and not the full resolution Raw. I would expect a full Raw file from the 7DII to be around 24 - 28 MB and have the pixel dimensions 5472x3648. M-Raws are smaller (4104x2736).
