My own purpose in the article was mostly to clearly show the parts that need to be modified.<br /><br />That said, this sort of thing doesn't necessarily require a high degree of precision. For instance, if you place a piece of opaque tape on the round shutter plate which covers half of the length of the kidney shaped slot, then the aperture is going to be uncovered roughly half the amount of time as when the part is unmodified.<br /><br />In regard to the size of the aperture, I would suggest taking a look at the variable aperture in a more sophisticated camera of about the same focal length as the Hawkeye Flash -- about 80mm.<br /><br />You can also, of course, calculate the desired aperture precisely since the f-stop value is just a proportionate relationship of focal length to aperture diameter. The standard way to express this is N=f/D, where N is the f-number, f is the focal length and D is the diameter of the aperture. Thus, if you want the aperture diameter for a given focal length and f-stop, the equation is D=f/N. So, if you want an aperture of f22 for your 80mm focal length, you need a washer with a hole in it that measures 3.64mm.<br /><br />That's all a bit wordy, so if you want a better illustrated explanation, take a look at the wikipedia article on f-stops.Mikehttps://www.blogger.com/profile/00776670666673938282noreply@blogger.comtag:blogger.com,1999:blog-1423901.post-55173920283108200652011-08-09T07:44:04.088-06:002011-08-09T07:44:04.088-06:00Hi Mike,

How would I know what size washer to buy to reduce the aperture and more importantly how did you fix the shutter speed with electical tape? I'm a bit confused on how to proceed from your directions that state: and shorten the length of the kidney-shaped slot with some tape. Any help you can provide will be greatly appreciated. Thank you.

One possibility which is illustrated in my web page on the camera is to brace it solidly on the ground to make your exposure.<br /><br />Another possibility that offers some of the same advantages as Krieger's hack is to follow the instructions by Diwan Bhathal for adding a tripod socket and a cable release to the Brownie Hawkeye Flash. A link to those instructions is provided in my web page on the Hawkeye Flash. I have one of the cameras modified by Diwan and it makes very nice images.Mikehttps://www.blogger.com/profile/00776670666673938282noreply@blogger.comtag:blogger.com,1999:blog-1423901.post-90534765227643164982011-08-02T08:58:32.656-06:002011-08-02T08:58:32.656-06:00I had a B-2 Cadet in my first, lamented camera col...I had a B-2 Cadet in my first, lamented camera collection. When I was dating the woman who is now my ex-wife, she was a professional photographer. She rolled some Plus X for me, and I shot the roll with the Cadet, and then she developed and printed it. The results were okay. Shake was a problem. The exposures were a little hazy, too. I published one photo from that roll on my blog a few years ago: http://jimgrey.wordpress.com/2007/03/18/photos-from-old-cameras/.<br /><br />With these tips you've shared, I want to buy another Cadet and try again!Anonymousnoreply@blogger.com
