Why isn't my Nikon D70 reading the SD card?
After taking many pictures from the Nikon D70, the camera all of sudden starts saying that it can't read any of the photos I've taken. Also, once you turn the camera on, a message saying FORMAT is blinking. I don't know what to do! I'm obviously an amateur photographer and any advice would be helpful.

Sandisk 16gb SD card is freezing my camera and computer why?
I have a sandisk 16gb SD card which I use in my Nikon D5100. I was using my camera for filming which I hadn't done before, the video was approx 10 mins long. My camera screen went blank during the end of this with a yellow egg timer. This remained and I was unable to switch my camera of and in the end had to take the battery out.
After trying to turn it off and on a again and leaving the camera running a message came up saying that the sd card was not working, I tried putting it into my laptop but my laptop froze, I was unable to access the information from the SD card or connect to the internet or open anything at all even the task manager to shut down anything unresponsive. When I removed the SD card the laptop worked fine and the Camera seems fine, although I don't have a spare SD card to try and take photos with.
I was just wondering what the problem might be and if there would be anyway of recovering the photos on the SD card without downloading or using any over software. Its not the end of the world if I can't, I wouldn't want to spend any money on recovering them but if there's a way it would be great to try!

What are the best effects in nikon D3200?
I'm not a photographer so i have no idea. But i see a lot of people having great photos with it and adding amazing effects that i have no idea about, anyone help?

I've had my Nikon d50 camera for a couple of months, and it has been working great! But, all of a sudden it is acting weird. I can take the photo, it flashes and makes the click noise, but when I go to review it it isn't in the list of photos. I've tried everything from deleting all of the images on the SD Card, to changing SD cards.
