Nikon d50 wont take pictures and displays r10 warning

I'm not sure what you mean by "multi-colour mode" but this page shows all of the possible playback display modes and describes them. Hopefully this helps you. I use a D7000 which is quite similar and I've never seen a multi-color mode. Nikon D50 SLR Review

SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.

If that doesn't do it, try a different card.

hi..
This screen shows areas of the photo that are overexposed slightly.
It flashes them to help you.
You get to this screen by pressing the up or down arrows when displaying the pictures you have taken.

To change it just press the up arrow when the camera is showing the screen until you get a display without flashing.

Once you have done this the display will be steady.
If you get any other screen in future you may have accidently pressed the arrow again.
Just cycle thru the displays to get back to steady.

thank u
rate me!!

That's the overexposed highlights display, to warn you when highlight details may be lost. Disable it by pressing the up arrow twice. First press shows you the histogram, second press shows pic only, no other info. It will remember this setting for all photos display (until you change it).

Perhaps you have accidentally set the auto-manual focus to manual on the camera body?

Per.

PS. The r10 message is just a report of the current memory buffer status, not an error indication.

NatD, The D50 and indeed most SLR digital cameras [ I have a D40 ] does not allow you to take pictures using the LCD display ... this is by design, you are meant to use the viewfinder and the image you see through it is straight through the lens via a mirror block [ called a reflex pentamirror or prism ]. When the mirror is down such that you can see the image in the viewfinder it is obscuring the sensor [ the bit that takes the picture ] and when you take a shot the mirror lifts and the picture is recorded. Its this reason that DSLR's dont use the LCD to shoot, however there are a few now available that do let you do this, such as olympus, new panasonic one and higher end Nikon and Canon cameras. Hope this explains it without getting too detailed!

Hi, the only thing I can see in the manual is on page 52 (below). You can scroll through the information provided using the up & down arrow keys on the multi-selector button. Scrolling though to the basic file info should give a clearer view. Perhaps if you select this option the next time you view it will default to it? I don't have the camera to try! Please update the question & let us know if the information given was useful to you - Good Luck!

Why cannot you return this one/ It is a fundimental fault seemingly. Doea it take pictures? Is the battery a good one- you say fully charged how do you know? Try another battery. first.

I have this problem too - Nikon have looked at the camera and said I set up a custom setting so that the focus only works when you press the AE/AF Button (!). I also had a problem with the flash not working - its looking like this is a known problem. I think I was sold a Turkey
