I like to know if this camera has a timer

I don't know, I don't know. I don't know. Perhaps you could tell us what brand and what model camera you use? And perhaps you can tell since when it is acting strange? like after you dropped it, or after it went down in the swimming pool. Or perhaps just after leaving it alone for a few days or weeks. Or perhaps after you changed some settings?

Press cursor-down (marked with a one-handed clock) to bring up the self-timer menu, use cursor-left/right to select the desired delay, then press the MENU/OK button. Start the self-timer by pressing the shutter release button as usual.

Full details are in the "Using the Self-Timer" section of the manual (page 39 in my copy). If you need a manual you may download a copy here.

Without knowing what camera you have, the most I can say is to find a button that looks like a timer or clock.

For a DMC-TZ3:

The button is called a self timer.

Press right on the multiselector (marked with a one-handed clock) to cycle through the self-timer modes. Once you've got the self-timer mode you want, start it by pressing the shutter release button.

From the menu, select Drive Mode (third item from the top) then one of the self-timer options. To start the self-timer, press the shutter release button.

Yes, it has a self-timer.

In the REC mode, press [MENU]. Use left/right to select the "REC" tab. Use up/down to select "Self-timer" and then press right. Use up/down to make your choice and press SET. Selecting "Off" in the last step turns off the self-timer.

Putting Yourself in the Picture The Self Timer creates a 10-second delay between the time you press the Shutter button and the time the picture is taken. 1 Place the camera on a flat surface or use a tripod. 2 In any Still mode, press the Self Timer button. The Self Timer icon appears in the status area. 3 Compose the scene. Then press the Shutter button half-way and hold to set the exposure and focus, then press the rest of the way down. Move so that you are in the scene. The Self Timer light blinks slowly for 8 seconds (then quickly for 2 seconds) before the picture is taken. The camera "clicks" when the picture is captured. To turn off the shutter sound, see page 64. The Self Timer turns off after you take the picture or if you change modes. To cancel the Self Timer before the picture is taken, press the Self Timer button. (The Self Timer setting remains active.) To turn off the Self Timer, press the Self Timer button twice.

Ok, you need to hold down the multi frame button on the top left of the back of the camera, then turn the dial (front I think) till it shows the little clock timer on the screen. It will give you a 10 second timer.

Easy, in camera mode, push the menu/ok button, use the left and right arrows to display the self timer mode. There are only 3 options on the menu. (self timer,cont,option). Once self timer is on the screen, use the up arrow to pick a short or long self timer.

Once it is set, compose your picture and press the release button as normal, the self timer will do the rest

Hi,

What camera model is it?

I can help you out but I need to know what camera model. Many cameras set their timer differently.
