HDR

HDR, High Dynamic Range, is becoming a very popular technic of processing photographs. It is a process of allowing a greater dynamic range from the very light highlights to the very dark shadows. This is usually done by taking several shots at different f stops, this is called bracketing, then stacking them and adjusting the composite image with special software. The image resulting can look more like the eye sees to be something totally abstract or anything in between depending on the images and the photographer.

I have played with this technic a little bit with varying success. I think that my most successful HDR is of the inside of San Fernando Cathedral in San Antonio. The photograph was taken about 2pm on a very sunny day so the light coming through the stained glass windows washed out most of the colors. I still need to reedit this photo and add the window with all its colors back into it.

It is comprised of 3 sections, right middle and left each with 3 brackets so a total of 9 photos were used. The method I used in processing this photograph was to process each section as an HDR then merge them together. This allowed me to work on keeping the halos down around the windows. I think I did a pretty good job on managing the halos and keeping it natural looking.

When I tried merging the sections together and then merge the brackets together as an HDR I was not happy with the results. It did not look right to me.

That is the nice thing about computers. You can try working with the photos in different ways and if you are not happy you do not have to save it while keeping your original files safe.

Does HDR work for all images. No, it is just another tool in the photographers toolbox to use when needed. I have seen HDR photographs by other photographers and while some have been amazing others have been awful. It really depends on the image and the photographer if this technic adds or subtracts from the photograph.

I hope that by next week I will have edited the photos I took on a recent trip so I can share them.

Orchids

Reccently I went to a local greenhouse during the week and was able to take pictures of some of their flowers. I usually like to be able to move the flowers around a little so I can get the best angle for the picture but this time I was not allowed to touch at all. So I had to try to get a good angle.

This Orchid photo was one of several that I took. I like how one bloom was in focus with the others less so and the background as totally out of focus. It has to me a peaceful garden look. I had a couple of people suggest that I should have tried a vertical photo. Maybe next time.

The settings for this photo was iso 400, f/5.6. 1/400sec

This next photo is of a Dragon Orchid. I am not as happy with this photo because I could not get futher away from it or an angle that I was happy with. This was one if I could have turned the pot a bit I could have moved a bit and gotten a better photo. Sometimes this is how life goes.

The settings for the Dragon Orchid photo was iso 400, f/11. 1/160sec

Trying Fireworks

Recently we went to a Minor League Baseball game, the Cedar Rapids Kernels, and after the game they had fireworks. They have fireworks after games through out the season so I can go back and try fireworks again and again.

I took pictures of the games and fireworks but want to share the firework photographs. I was hand holding the camera for all of these shots. I will talk about how I could improve them after the photos.

Fireworks one. iso 800, f/3.5, 1/20sec

Fireworks two. iso 800, f/3.5 1/20sec

Fireworks three, iso 800, f/3.5, 1/10sec

All of these photos have the same problems.

1- I had my shutter speed too slow. I should have had it at 2-4 sec which means that I would have needed a tripod of someplace to set my camera.
2- too low of f stop. A higher f stop would have helped because I would not over expose the image with a slower shutter speed.
3- lower iso. This would have allowed for longer shutter, lower noise and better quality image.

If I had done these I would have had more colors and longer tails which would be more interesting to look at and come closer to what we see with our eyes.

In images one and two more in the foreground would have helped make a more interesting by giving more dimension to the images, where as image 3 had things in the background that added interest.

I will try again with fireworks and share my results. While I did not photograph the firework well I did learn what I did wrong so I can improve next time.

A Beginning

I am going to try blogging again. This time I am going to write about something I have fun with and want to improve my skill at- Photography.

I am not much or a portait photographer but I do love taking photos of architure, nature and things around me. I am getting more into Macro photography.

Not all my posts will have photos but at least one a week will be a photograph. My assignment for the year is to post a photograph a week. This does not mean that all the photos will be good. It does mean that for one reason or another this is a photograph that I want to share. It maybe that there were mistakes in the photo or I am trying a new technique or it is one I like or it could be that I think it is good.

I will appreciate all comments, others looking and commenting on my work as well as passing on tips and links will help me to improve as a photographer.

As to my camera. I am using a Canon T2i. It fits my hands well and was afforable and has been very dependable. I have had very good luck in the past with Canon cameras. I have an old Canon Powershot that I took on a trip and unfortunately it was dropped on to a tiled concret floor several times and continued to work for a few more years.

My lens are: a EF-S 18-135mm and Canon EF 100mm Macro. I am looking at other lens but right now I have to wait a bit before I can buy another lens. I occassionally rent lens to try out so I can decide which lenses I would like to buy and will post my results and my opinion of the lens.

I think that I have rambled enough. Welcome to this adventure of this dangerous combination: A Mom (me) and a Camera.
