TIME STACKING

I mentioned the other day about time stacking. This is taking a number of the same photos with a fixed and moving object(s). Open the first pic in Photoshop which will become your background layer. Add the second photo on a new layer. Change the top layer blending mode to " lighten " and merge both layers together. this adds only the parts of the second image that are lighter thn the background (Original ) image. once merged the remaining image is still the background image.-repeat the process as many time as you want or have taken pictures for.
You'll need to have your camera mounted on a tripod when taking the images so the imovable part is sharp. A remote shutter release will be most helpful if not a must ?
this one is 10 in the stack. A lady walked by so I put her in number 8 !!
this is my first go - I think a changing light at sunset would have been better and I'll be giving it another go ! what you think??
