Tech Tip of the Day. I helped my neighbours today, B had lost a file on her High School Laptop. Apparently they use the Cloud at High School now. Microsoft Cloud……..

I went back to the old ways, I opened a command prompt, I was in B’s home folder (/Users/studentid,http://en.wikipedia.org/wiki/Home_directory).

I then ran the command “dir file_prefix* /s /b” where file_prefix was the first word in her lost file name, the * (star or asterix, obelisk is another guy) is the wildcard character.

In plain english this means anything starting with the word file_prefix, e.g. “find any file starting with important_assignment”.

Several files were found then the modified date (I was looking for the most recent date, ideally today) was reviewed and voila, we found the “lost” file.

I copied this file from its location to her Sky Drive or whatever its called and B was back on track.

I suggest you bookmark, save, store this information for a rainy day.

Depth of field is greatly influenced by the focal length, using a long lens, 300mm for example, means that F5.6 is like F4.0.

This photo shows this in action, the nice blurred background here is also aided by a good deal of depth in the subject as well, position yourself where you can get great depth in the photo. The depth will great enhance the depth if field.

The 10 Commandments of Photography

 

Here’s something new. A photography article with no pictures.

There is one rule you need for taking great photographs. It was a favourite saying of noted British nature photographer Heather Angel and most of the 10 Commandments come from this simple phrase:

"f8 and be there"

Read on to see why that’s all you really need to know.

  1. You can’t take a picture without a camera. Take one with you everywhere because you never know what you will see or where or when.
  2. You can’t take a picture without the camera being ready. Keep it clean, fully charged and with enough memory/film to take the shots you find. You might well have a fairly small and simple one on you at all times. It will be the one you use when you’ve left the SLR in the car because it was too heavy.
  3. You can’t take a great picture without knowing how to use the camera. Learn how to turn it on and take a shot on auto without looking at it.
  4. You can’t take a great picture on auto. Well you can but it might well be better if you know how to override.
  5. You can’t take a picture without a subject. Get up and go somewhere with a camera, some time and a photographic intent.
  6. Shoot early, shoot often. Many opportunities are lost looking for the perfect shot. Take every shot, angle and subject as soon as you can. As the light or subject changes, shoot more. You can edit or delete later. Take your first shots on Auto and worry about fine control later.
  7. You need to ‘see’ the pictures that are there. This is practice and study. Take lots of photos and look at other peoples. Best of all go out for a shoot with another photographer. Learn what they see and how they render the same subject. You can learn both technical and graphical skills at the same time.
  8. Get the gear. While most cameras will do a decent job on everyday things, you need something better to take challenging images in challenging circumstances. Most people also don’t master the basic accessories of every camera – the flash and the tripod. Learn when and how to use them.
  9. Go to extremes. Most people can find everyday subject with everyday skills at the ordinary time of day. If you want to impress go for something they can’t shoot – an extreme close up, an ultra-wide shot, a super tele shot of a bird, a flower only you can find, a night shot of the city.
  10. You need to know how to throw away the images that are not strong. In the field that means keep shooting until you know you have the best you can get. At home it means editing and culling the duds. For showing it means only the best. Leave the audience wanting more.Show only the ‘wow’ images. Less is better.

 

I always find it hard to picture these BIG numbers in my head, so here they are in simple form with comma’s between the 0′s to give them a little length.
