Double Exposure
A while back I asked if any digital cameras did double exposure. I
found out the Nikon D200 does. Now I find that the Nikon D40 (and possibly other cameras) has the capability to overlay two images, which to my way of thinking is exactly the same thing. The only problem is they have to be RAW, which is okay if you normally shoot RAW but not if you shoot jpeg. Nevertheless, there is no reason, on the rare occasion when this is necessary, not to switch to RAW and then to switch back. You can download the RAW image and convert it to jpeg for future use. -- Robert B. Peirce, Venetia, PA 724-941-6883 bob AT peirce-family.com [Mac] rbp AT cooksonpeirce.com [Office] |

You can download the RAW image and convert it to Does it make much sense to choose a camera based only on this feature? If you normally use jpegs but will have to switch to raw to take advantage to use this feature, you are adding an extra step (conversion). But if you do allow an extra step, you might as well take the two exposures as jpegs as you (presumably) normally would and then add them together in an image editor (for example, the gimp, which is free, so you don't need to buuy anything extra). This may free you up to make a decision based on other criteria. |

The D200 (at least) has two methods for combining multiple exposures. The first is Image Overlay. This combines two RAW files and leaves the originals intact as seperate files. You can adjust the gain for the two pictures from ..1 to 2.0 and see the effects in the preview image. The other method is Multiple Exposure which allows you to combine up to 10 exposures as a single photograph. They need not be RAW, but the original images are not saved. The way it works is you select Multiple Exposure in the shooting menu and then choose the number of shots that you are about to take. They are then combined in-camera. You can turn Gain on or off. With it on, the gain is adjusted for each picture, 1/3 for three exposures, 1/2 for two exposures, etc. You cannot change it. EXIF information will be for the first exposure and you can use the interval timer. You cannot use bracketing in Multiple Exposure mode. -- Waddling Eagle World Famous Flight Instructor |

My Pentax *ist D can do up to 9 frames, I just skimmed through the K10D manual and it offers the same function. http://www.darrelllarose.ca/gallery/album03/hopping2 is an example of multi-frame exposure (6 frames) |

I just got a new camera that does RAW along with Fine, Normal and Basic jpg, the difference being compression levels. As a preliminary test, I took four shots of a completely flat, blank wall, to see what artifacts would be created by printing, and I took four shots of a picture frame running diagonally across the picture to see what jaggies I might find. There are other tests to do, but these are a start. The pictures are 3000x2000 pixels. At 300 dots/in. they would make a "natural" picture of 10"x6-2/3". I decided the largest print I might ever want to make with this camera would be 30"x20". Actually, 18"x12" is probably more realistic, but I wanted a difficult test. I took a 1000x667 pixel crop of each of the eight images and printed them on 6x4 paper. Aside from some minor color differences, which can be corrected during editing, I really could not see any difference among them without using a loupe! I was frankly amazed. The picture frame, viewed through a loupe, showed some softening on Basic vs. RAW, but it wasn't apparent to the eye. I have read this might be the case, but I didn't believe it. If you have never tried this, you should. It may depend on the camera and lens you use. I don't know about that. However, I do know you can prove to yourself whether it matters with your equipment. There are some other tests I want to do, but so far I have concluded RAW isn't necessary and Fine probably isn't either. I don't know if I'm ready to go Basic, but Normal looks like it would work just fine, pun intended. -- Robert B.

If you shoot in Raw you can always convert back to a jpeg if that your thing. Where you see the benefits of shooting raw is when you have to control highlights or do some sort of editing of the image before printing. -- "As democracy is perfected, the office represents, more and more closely, the inner soul of the people.
