Hacking Digital Cameras 102
whawk640 writes "I came across this book via the author's website www.camerahacker.com. I was interested in making a pinhole lens at the time so I picked up the book. Disclaimer: I'm NOT a hacker by nature. I only did a hack on a lens cover. Most of the hacks in here are for those with a better relationship with screwdrivers, drills and soldering irons than I have. I don't think this book was intended for me, so keep that in mind when reading my review." Read the rest of Daniel's review.

summary | Interesting and Fun |
A quick list of the types of hacks in the book are as follows.
1: Hacking Cameras -- (triggers, tripods, raw data, power, remote control and updated firmware)
2: Hacking Lenses -- (accessory adapters, changing magnification, pinhole, lens extension, macro adapters)
3: Creative Photography Hacks -- (filters, infrared, and removing infrared blocking)
4: Building Fun Camera Tools -- (car mount, headrest mount, bicycle spy cam, stabilizer, flash bracket, monopod, and studio light)
5: Flash Memory Hacks -- (CF Type I to PC Card Type II, removing microdrives)
6: Appendices -- (Soldering Basics, Circuit Symbols, Glass Cutting Basics, Photographer's Glossary, Index)
This book has quite a few hacks and if you're interested in hacking, the step by step instructions presented in the book will be useful and interesting. Quite honestly, I've only performed one of the hacks myself. I followed the step by step instructions for making a pinhole lens and it worked just perfectly. My wife will tell you I'm no Bob Vila. About all I know about a drill is that one end is pointy and spins.
Anyway, if you want to tinker with digital cameras, pick up the book and read through the contents. If the specific hack you want to do is not in the contents, look for something close. If it's not there or the book doesn't give you any ideas on anything to do, then it may not be for you. Read one more paragraph to find out.
In addition to the hacks, this book covers quite a bit of introductory concepts in photography in general and the math behind it. I found it easy to read as a beginner and it gave me an appreciation for why there are professional photographers and 'the rest of us'. Concepts covered in the book include focal length, magnification, filters, softness, ambient light, field of view, white balance, infrared, ultraviolet, depth of field and many more. These sections are brief and provide only an introduction though. If you're an experienced photographer, you probably won't find anything new in these sections. One down side about this is that since an introduction to photography is not the focus of the book, these introductions are scattered throughout the book whenever they tie in with a specific hack. On the upside, it gives you the information when you need it to decide if a hack is right for you.
Now, the hacks in the book are step by step with loads of pictures, schematics where necessary and tips. What you need to perform each hack is identified clearly before you start. Additional ideas about how the hack could be modified in function or in fit are available after each hack.
In my opinion, the disclaimer telling you not to take apart your $400.00 brand new camera is not quite strong enough. People like me are rightly afraid of that sort of thing. From what I hear, your average hacker though is much more adept and less fearful.
This is not the type of book most people would pick up and read cover to cover. It is more like a reference you would want to have handy if you spend a lot of time taking creative pictures or messing with your camera.
Negatives: Hacks seem to apply to specific cameras, if you want to apply them to other cameras, the author's experience may not help you... be careful! I found section 3 very interesting and would have liked to see more chapters on fun camera hacks. Unfortunately, it was the smallest section in the book.
Are you a propeller head who loves to take things apart?
Are you a techno-junkie who has 9 or 10 digital cameras lying around because you always buy the newest one?
Are you an amateur or professional photographer who just can't quite get all the features you want in a single camera?
Do you have a specific need for a hack that the book covers?
Do you have an interest in this sort of hack and a desire to learn some photography basics?"
If you answered yes to any of the previous questions, then this book is for you.

If you did not want to use a colored filter over the lens, I would think that this would be best done in post-processing with software. Most CCDs in cameras have Red/Green/Blue filters over each (very tiny) lense to pick up the component primary colors of a photo. It would be easier to build/buy a camera with just a greyscale CCD.
Hacking the CCD would be last place to accomplish this. You do not even need to open your camera.

They detect colors by how far the photon embeds itself within the silicon. You could just take the raw data from the camera and sum the R, G, & B portions of every pixel to get a raw photon count. Then just gamma correct and you'll have a true greyscale image.
I would recommend using dcraw for this, as it would probably just be a quick hack.

One of the topics listed in the book is the raw file format. Why do camera manufacturer encrypt our pictures? Our pictures belong to us. We are the copyright holders of our pictures, not the manufacturers of cameras. There is probably no acceptable answer.
I followed your link, and I think your right, there is no acceptable answer to that from a user standpoint. Looking at the information from your link this sounds like a rather lame attempt at locking the camera to the raw processing software.
Its odd in that the image itself isn't encrypted but the white balance information is. It obviously takes additional work to encrypt the white balance, so why not the whole image? Probably its Nikon walking the line between irritating the software developer enough to drop support entirely, yet still keeping them from accessing the full potential of the raw file (locking out the open-source community - good job there Nikon...)
Another case of the corporate mentality to maintain complete control over what you can do with the stuff you buy.

Nikon is adding a new layer of obscurity by encrypting the WB info (maybe so that they can sue using DMCA).
All RAW formats and Adobe DNG are basically TIFF files, but the tags are different. Of course, there no reason why there shouldn't be a standard format used by everyone.
So far, DNG is used natively by some medium format cameras such as Hasseblad's digital backs. DNG specs are open.

At best, encrypting the WB setting makes things mildly more annoying for if you're working with a 3rd party RAW converter. The reason I say this is because I know a number of photographers who don't use WB when shooting and instead handle that in post-production. Others may set the WB simply so tha
