Great luncheon! Here is the very brief ...Hi Anne. Great luncheon! Here is the very brief summary of camera exposure information that I mentioned. Enjoy! Bill<br /><br /><br />Exposure Basics<br /><br />A perfect exposure is like a bucket filled precisely to the brim.<br /><br />A less than full "bucket" results in underexposure, picture too dark; <br />An over-full bucket means the picture will be washed out, overexposed.<br /><br />There are 2 possible approaches to filling the bucket:<br />You can open the faucet all the way and run the water for a very short time; OR<br />You can open the faucet only a little and let the water trickle for a much longer time.<br /><br />The "faucet" corresponds to the lens opening, the aperture; the length of time the faucet is open corresponds to the camera's shutter speed.<br /><br />Either approach can result in a perfectly filled bucket.<br /><br />The two approaches are complementary: Reduction in one can be precisely compensated by increase in the other, leaving the level in the bucket unchanged.<br /><br />The unit of increase or reduction in light is called a "stop" or "exposure value" (EV). An increase of one stop in the aperture setting will be exactly balanced by a decrease of one stop in the shutter speed, and vice versa. <br /><br />Increase of light volume by one stop--by whichever means--is defined as a doubling of the light reaching the sensor; decrease of light by one stop is an halving of the light.<br /><br />Shutter speed controls motion.<br /><br />Whether the motion is that of a moving subject or a photographer's shaking hands, its effects will be exaggerated by a long exposure and minimized by a short exposure. Even very rapid motion can be frozen by the use of a very fast shutter speed. Even slow or slight motion will result in blur when a slow shutter speed is employed.<br /><br />A useful guideline for avoiding camera shake is to use a shutter speed no slower than the reciprocal of the focal length of the lens. That is, if the focal length of a lens is 50 (mm), its reciprocal will be 1/50, so the slowest shutter speed to use is 1/50th of a second.<br /><br />Aperture controls depth of field, the zone of sharpness which begins at a given distance from the lens and extends to some other distance, which could be infinity.<br /><br />It is a fact of optics that depth of field varies with the aperture diameter: a smaller diameter (higher f-number) will result in greater depth of field; a larger diameter (lower f-number) results in less depth of field.<br />Anonymoushttps://www.blogger.com/profile/02284304351680068417noreply@blogger.comtag:blogger.com,1999:blog-8448820564852330128.post-46542820028485111442016-11-26T08:16:25.034-08:002016-11-26T08:16:25.034-08:00Yes, we are pleased with it, so are Simons hands.Yes, we are pleased with it, so are Simons hands.Renovation in Galiciahttps://www.blogger.com/profile/12134753603087085719noreply@blogger.comtag:blogger.com,1999:blog-8448820564852330128.post-40159138868648428332016-11-25T10:05:13.383-08:002016-11-25T10:05:13.383-08:00So glad the machine worked and was a worthwhile in...So glad the machine worked and was a worthwhile investment!

I was interested in your comments about the huge weight range on this latest batch - we have also found this. There are some 'tiny' hens whom we thought must be sick in some way and not thriving but they seem to be chugging along OK, and some of our cock birds are huge by comparison. I will weigh this lot and let you know. Like you, we have fed and ranged them this year the same as previous years.

We have a plucker that looks very similar to yours and works well. The dogs love this time as they get all the heads, feet and innards. We're worn at at the end of the day but as we just cannot tolerate any store bought chicken we know the day is just one more invested in our ongoing health. Enjoy your chicken!Donna OShaughnessyhttps://www.blogger.com/profile/08266654110280149719noreply@blogger.com
