  • Annual Appraisal

    Have just completed my annual appraisal which went very well, at least I didn’t get the sack. Actually am very pleased most of the ticks were either in the good boxes with three or four in the excellent box, and a couple in ok boxes. The written assessment was good and I have no complaints, so I am now a happy bunny. 

    On the down side my breathing is laboured once again and I feel my voice will pack in at any moment, at this rate I will be soon on the sick once again. I hope not I want to go to Yorkshire, visit my dad and do a bit of walking and lots of photography, I need to get over this fast, I still think my asthma playing up, Rosemary thinks it’s a chest infection (which am prone to as well). Which ever I just want to get over it!

  • Hard to Concentrate

    Am really struggling this morning to get back into the swing of things, am finding it hard to concentrate and am lost at what to start first. The price you pay I suppose for being off sick over the last couple of days.

    Am still waiting for my annual appraisal, it was supposed to be at 10:00 but has been put back a couple of hours because no meeting room was available.

    Roll on the weekend, can't wait to go to Yorkshire

  • Exposure

    Exposure is the amount of light collected by the sensor in your camera during a single picture.  If the shot is exposed too long the photograph will be washed out.  If the shot is exposed too short the photograph will appear too dark.  Almost all cameras today have light meters which measure the light in the given shot and set an ideal exposure automatically.  Most people depend on the light meter which is fine, but if you know how to control your exposures you can get some creative and sometimes better pictures. 

    The two primary controls your camera uses for exposure are shutter speed (the amount of time the sensor is exposed to light) and aperture (the size of the lens opening that lets light into the camera).  Shutter speeds are measured in seconds and more commonly fractions of a second. (1/2000 of a second is very fast and 8' seconds is extremely slow).  Apertures are measured in something called f/stops (a very wide aperture is f/2.8 and a very small aperture is f/19).

    You might wonder why there is not just a constant shutter speed or a constant aperture so that you would only have to worry about one control.  The reason is that even though they both control the amount of light getting to the sensor they also control other aspects of the picture.  Shutter speed for example can be used to freeze subjects in midair with a fast speed or it can be used to blur water with a slow speed.  Aperture controls the depth-of-field which is what is in focus in the picture.  Aperture can be used to draw attention to one subject by blurring the background with a wide aperture (low f/stop).  Aperture can also be used to focus everything in a picture with a narrow aperture (high f/stop).  (The photo on the left is with Wide aperture (low f/stop) and corresponding shutter speed).
              

    On most digital SLR’s cameras today you can even change the sensitivity of the sensor when collecting light which is called the ISO speed.  The common span of ISO speed is 100 to 800.  The higher the ISO speed the faster the camera collects light but it also adds more noise to the photograph than the lower speeds.  For example if your trying to take pictures in dim light without a tripod you might want to raise the ISO speed in order to get a picture that's not blurry.  Most of the time you should keep it at a lower ISO speed if there is enough light, but it makes a big difference when there isn't.

  • Back to Work

    Monday morning and I’m back at work, I still don’t think I am 100% but I really can’t take any more time off work. So am sat at my desk and I will just have to be careful what I get up too.

     

    Well its annual appraisal day hopefully it will go ok. I not really worried, what will be, will be no matter what I do now.

     

    Have just checked the five day forecast for Yorkshire and it looks good until Friday, which is as far as it predicts and it looks good so hopefully we will have a great bank holiday. Am going Saturday morning and back on Tuesday, well that’s the plan so far.
