First of all, I want to thank everyone for stopping by last week to comment on my post, especially those who really liked the photo of the reflected boat sheds (a lot of blue). I had entered that photo on Red Bubble, and it was featured in the Beautiful BC Group on Friday. So thanks again!
One of the most difficult things for me to understand so far in my study of photography is the F-Stop. I think it's because I don't have an SLR camera, but rather a high-level digital. I only get to practise changing the aperture settings to a certain extent, so it's still a bit of a mysterious part of photography. I will try to explain it so you and I both will get it, though. This is all thanks to many websites I've checked out so here goes.
First, we have to understand what "aperture" means. It is the opening formed by a system of metal leaves in the lens that open up and close down to control the volume of light passing through the lens. It is the lens's equivalent of the iris of our eye. (from here) Keeping this in mind, the F-Stop is the number given to indicate how much light is allowed through the lens. Simply put, the higher the number equals less light allowed in and the lower the number equals more light allowed in. A photo taken at F-2 will be brighter than a photo taken at F-16. Here are a couple of examples of photos I took of a rose at different F-stops. The one on the left was set at -2.0 and the one on the right was set at +2.0. Neither is right for the photo, but from practise, I found the proper setting.
Something that my photography tutor suggested is that when you upload your photos, always save the original in a special File. Then when you crop, resize, adjust contrast and levels, etc. save it again in a different File. That way, if you want to try different things like colour, saturation, cropping and sizing at another time, you'll always have the original to work from. I have to admit that I don't always do this except for photos that I consider to be first rate. My cameras seem to take photos in 72 or 96 dpi, too, so I always change it to 300 dpi. Here is an example of an original photo that I cropped and increased to 300 dpi. It was taken in Italy in 2006.

- I took very early retirement from teaching in '06 and did some traveling in Europe and the UK before settling down to do some private tutoring. As a voracious reader, I have many books waiting in line for me to read. Tell me I shouldn't read something, and I will. I'm a happy, optimistic person and I love to travel and through that believe that life can be a continuous learning experience. I'm looking forward to traveling more some day. I enjoy walking, cycling, water aerobics & and sports like tennis, volleyball, and fastpitch/baseball. I'm just getting into photography as a hobby and I'm enjoying learning all the bits and bobs of my digital camera. My family is everything to me and I'm delighted to be the mother of two girls and the Gramma of a boy and a girl. I may be a Gramma, but I'm at heart just a girl who wants to have fun.
