I started off reading eBooks from the Amazon Kindle store. As time has progressed, I’ve found myself using my physical Kindle less and less. Partly because I forget to charge it, and partly because I can never get the lighting in my favorite reading locations quite right. And at night? Forget about it.
So I’ve converted all of my Kindle purchases to ePubs for use in iBooks. I could use the Kindle app for iOS but I’ve found iBooks to be faster at syncing read position, and it feels a lot more natural to use.
Since I went through the effort of converting all of my Kindle documents, I figured I’d write a mini guide to getting it done. I’m specifically focusing on the Mac since that’s all I know; other users will have to venture elsewhere.
Setting up Calibre
Calibre is a Java application which is an eBook management suite. It’s a bit ugly but it does what it says and works well. Since the Kindle’s eBooks are encrypted, we need to install a decryption plugin to do the heavy lifting there.
Choose the K4MobileDeDRM plugin’s zip file (zip within the main zip; don’t extract).
The encryption used on Kindle books is fairly basic. The decryption key is a product of the serial number for your device, so it’s not difficult to determine.
The DeDRM scripts work by understanding Kindle for Mac’s settings files, so to get the eBooks we need use the application. There are scripts to do conversions directly from Kindle hardware’s eBooks, but it’s more effort.
Download all of your eBooks (open them from the “Archived Items”).
Kindle eBooks are in the MobiPocket format. However, iBooks requires ePub, so we need to both decrypt and convert the files. At this point, we’ve got all we need, so we can use Calibre to do the conversion.
Navigate to ~/Library/Application Support/Kindle/My Kindle Content/
Drag all of the .azw files into the Calibre window.
Select the books in the Calibre window which you wish to export.
Click the “Convert books” toolbar item.
Choose “ePub” as the output format in the top-right of the convert window.
Go to the “Page Setup” item in the left list, and configure the conversion as so:
Select “Kindle” as the input profile.
Select “iPad” as the output profile.
Hit the “OK” button to begin the conversion. It may take a while.
If you have any issues at the decryption step, you should delete your~/Library/Application Support/Kindle folder and start again.
You can now “Save to disk” from the toolbar item to save the books which you’ve converted, and import them into iTunes for use in iBooks. Calibre is powerful enough to do many other formats if you want to use other devices as well.
Remember, don’t post any of the unencrypted documents anywhere. Just because the DRM is gone doesn’t mean you’re legally authorized to do so. They’re for your personal use only.
Format refers to the size of film that you are using.
Medium format mostly refers to 120 film which will be 6cm wide but depending on the camera you are using can be 4.5,6, or 7cm long and even longer which would go on to a large format camera. Our cameras produce negative that are 6 X 6cm and 6 X 7cm. We would advice that you do not use 220 film as it doesn8217;t have a paper back and can rip and is difficult to load, also some of our cameras are not designed for this longer film, So please stick to 120 film.
We do have a Polaroid back for the Mamiya RS67 for this you need to buy Polaroid film.
Lots of older medium format cameras don8217;t have built in light meters and so you will most probably have to use an external light meter. Saying that we do have a metering hood and metering pentaprisim but we would advise you to use a hand held light meter.
Light Meters help to give an accurate light reading which will be converted into the appropriate shutter speeds and fno relative to the film speed ie ISO. When using a light meter first dial in the correct ISO, then set the mode to either ambient, flash non-cord or flash cord, dependant on your lighting. For a general reading point the meter at the subject from the position of the camera and take a reading.
For a brightness-range take a reading from the brightest part and the darkest part then split the difference. Using a grey-card measure the light reflected off it. For incident-light reading use the white plastic diffusing dome then meter the light that is fallin8217;g This methods will not take into account close-up work, filters on the camera or very long or very short exposures.
Most medium format cameras require you to both cock the lens and wind the film on as two separate actions unlike most compacts and 35mm cameras where both these actions are carried out simply by winding the film on.
How do you utilise mixed lighting indoors? What problem arise and how can you solve them? This article by David Askham will give some of the answers, based on the author’s experience in a wide range of commercial assigments in work places, stately homes and domestic interiors. …
Want to play around with SLR Camera settings and see how it affects your photo, but without actually using an SLR? Well, you can do just that with the Online SLR Camera Simulator. This simple application allows you to choose the lighting, ISO, shutter speed and aperture. A great tool to teach someone the basics of photography.
The most realistic and usually most pleasing lighting resembles daylight, the light we see most often: one main source of light from above creating a single set of shadows. Lighting seems unrealistic (though there may be times when you will want that) if it comes from below or if it comes from two or more equally strong sources that produce shadows going in different directions.
Good tones are obtained with normally exposed and developed conventional paper prints. Some modern papers even those described as 8216;fibre8217; are liable to give variable results and 8216;blotches8217;. It is recomended that prints are given full exposure, and development, an acid stop, fixed in a simple non hardening fixer, and copiously washed. Work only under subdued lighting. 8230;
Naturally the diagrams should only be taken as a guide, as it is impossible to accurately represent the enormous variety of heads, dishes, softboxes, reflectors and so on that are available, while using an accessible range of diagrams, nor is it possible to fully indicate lighting ratios and other such specifics. In practice, however, differences in equipment, and sometimes scale, should be small, and will anyhow at allow you to add your own personal stamp to the arrangement you’ re seeking to replicate. In addition you’ll find technical details about the use of camera, film, exposure, lens etc. along with any useful hints and tips.
