What are you trying to do? "Create a image within an imade (image?) using shutter speed"? If it's what I think you mean, you could increase your shutter speed to a few seconds (use a tripod) and then use a flash to expose the first image, and then another bright flash to expose the 2nd image. It will take some trial and error to get it right. :)

Is that what you wanted to do?

Or you can set the shutter to like 6 seconds, take the first pic, put a black card in the way of the lens, then place the second subject and remove the black card...?

Hi Roger

I'm not sure about specific settings on your camera, but what I would suggest is you get exposure readings from the two objects you want to overlay, then calculate how long you need in between the shot to move the camera. Total up the seconds, then as Mavrik suggested, put some black cardboard in front of the lense as you move the camera.

One of my submissions illustrates this effect (except I did not put cardboard in front of the lense as I moved the camera). Have a look at //www.dpchallenge.com/image.php/i/13748. You will have to experiment to get the effect you want.

Good luck!

so while the camera is exposing move the camera to the second subject i may only have 4 seconds to do this ? and while moving put black board in front of lens then remove and let camers take the rest of the same shot? do i have it or am i missing something?

Yes, that is correct.

Is your camera limited to 4 second exposures? That might make it difficult. But give it a go! Try without the card too and see what happens. Its just a matter of experimenting.

If you can do longer than 4 seconds, give yourself a little while to move the camera and line it up. Not sure about your camera, but when mine is taking a shot, it doesn't show on the lcd or viewfinder what it is taking, so on my bridge shot, I had to guess where it was pointed for the second part of the photo.

Hope you get the results you are looking for! Make sure you share some of your samples with us! I would be interested in seeing how you go!

ok i got it but i dont what should i do? f stop range is 3.0 and 6.7 for wide angle and 3.6 and 8.0 in telephoto? in manuaul mode shutter speeds can be changed in half stop increments between 1/100 and 4 seconds? which setting should i choose or is my camera capable?

It will depend on the lighting conditions when you are taking a photo. Because your shutter speed is limited to 4 seconds, you will need a lot of ambient light, or a good flash gun.

Get light readings on both your scenes and make sure the exposure is not over exposed at say 1.5 second exposure and a low F number (meaning it allows more light in). You'll probably need to allow 1.5 seconds on each scene, with about a second to move the camera in between. This means you probably wont have time to put a card in front of your lense! Once you have confirmed the exposure at 1.5 seconds for each scene, bump the shutter speed up to 4 seconds, ignoring the fact that the camera says it will be overexposed.

You'll need to count the seconds as the photo is being taken and time everything to precision to get it right. That will come with practice. I think your camera is capable of this kind of photography, provided you have a well lit scene, or you can get a flash gun and manually set it off while pointed at each scene.

Never assume that your camera is not capable of something without first trying it out! You'll be amazed at what you can come up with, even on a limited feature camera! This is the best way to learn - push the boundaries of your camera!

Let me know if there's anything else I can help you with.
