Sunshine Through The Rain[ edit ] There is an old legend in Japan that states that when the sun is shining through the rain, the kitsune foxes have their weddings this is a common theme globally — see sunshower. In this first dream, a boy defies the wish of a woman, possibly his mother, to remain at home during a day with such weather. From behind a large tree in the nearby forest, he witnesses the slow wedding procession of the kitsune. Unfortunately, he is spotted by the foxes and runs home.
Could you send me an executable? Why does dcraw say "Out of memory" in Windows Vista? This limitation can be removed by some combination of service packs and registry hacks, or you can compile dcraw to use the newer Win32 API.
Dcraw only supports cameras. Try this simple program for scanners. Do you have any specifications describing raw photo formats?
Yes, but they tend to omit important details, like how to decompress the raw image or decrypt private metadata. Where can I get an assortment of raw photos to test my software? For the latest cameras, I get samples from Photography Blog.
A "Full Review" at Imaging Resource usually includes a few raw shots. How do I convert its raw photos into something that dcraw and Adobe Photoshop can open?
Why are dcraw output images larger than camera JPEGs? Any algorithm that combines each pixel with its neighbors is going to have problems near the edges. C code is cheap, so dcraw applies a different algorithm to edge pixels.
Hardware logic is expensive, so cameras crop off the edge pixels after processing. I shot a raw photo with no light. Why does it appear all noisy, when it should be solid black? The "-W" option avoids this behavior. See the previous question.
If you want pretty pictures straight out of dcraw, stay with 8-bit output.
What does the "-f" four color RGB option do? If you see patterns like this or this in your output images, first try "dcraw -a". If these patterns persist, use "dcraw -f" to get rid of them. To write other formats: ImageMagick also does command-line format conversions.
I have decided that dcraw shall be a command-line program written in C, and that any further abstraction layers must be added around this core, not inside it. Library code is ugly because it cannot use global variables.
Libraries are more difficult to modify, build, install, and test than standalone programs, and so are inappropriate for file formats that change every day. Run it as a separate process. Eric Raymond explains this technique here. Why are there false colors along edges within the image?
This is a hard problem, easily defined: Take a three-color RGB image.
At each pixel, set two color values to zero. Reconstruct the original three-color image as best you can from the remaining one color per pixel. Dcraw currently gives a choice of four methods: The Foveon X3 Capture chip requires a different kind of interpolation.
Unlike CCD arrays, it captures three colors at every pixel location. But the colors are not well separated, so the raw data looks very gray. Much processing is needed to enhance color while suppressing noise.Back to Dave Coffin's Home Page Decoding raw digital photos in Linux en Esperanto em Português auf Deutsch на русском па-беларуску.
My Photographic Beginnings. The first camera that I owned was a Kodak Brownie that was a present given to me by my brother Jim when I was about ten years old. New York City Through the Years This page has been viewed more than , times; thank you so much!
The response to my LAX Through the Years photo essay has been overwhelming, and prompted me to create a similar page for the two main New York airports, La Guardia (LGA) and John F Kennedy International Airport (JFK), originally known as Idlewild (IDL), although its official name was New York.

In the 19th century, through an artistic and literary movement known as “Japonisme”, French poets appear to have been solely attracted by the evocation and illustration of Japanese works of art such as color-prints or curios, which they .
