Patterns and Light Study

Posted by Greg On October - 23 - 2009

Recently I have built a photographic table in order to improve my photographic skills, and now I am studying light and compositions. By studying I mean reading some books, looking at many photographs from a good photographers, and, of course trying to shoot myself.

In this photo session I was trying to create a repeatable pattern from some cups that I have. I saw that I could arrange them in some interesting ways but something was missing from the overall composition. After a long hard thinking and trying I finally came up with the idea of grapes. When I added grapes to the composition, I felt that they contributed a lot and I tried to arrange them in various shapes. By the way, I had to wash these grapes pretty hard in order to get rid of any dirt and fertilizer remnants.

In the first two photographs you can see two of the most successful patterns I could come up with.
However I had one more problem during my shoot – the Light. I had only one flash and it was without any diffuser, so I had to find a right place for it, so that the final lighting would be satisfactory.

I finally placed the flash on a stand on the right side of the composition, about a meter above, and not facing directly to the subjects but pointed “above” them, hitting a white wall behind.

You can see that the shadows inside the cups in the second photo are going rather steeply down as a result of flash placement. I also had to shoot my composition at such an angle that these shadows (inside the cup) wouldn’t be too harsh and too visible.

Another important thing composition-wise was to make the reflections remain in the frame, which gives additional dimension to the final photograph.

In the third photograph I tried to create another interesting form. Originally this photograph isn’t as tightly cropped, but putting it in this slideshow somehow cropped it. I am still new to making slideshows like that, and I will have to figure out why it happened.

Will be glad to hear any opinions and to answer any questions regarding these photos.

How to create HDR image in Photoshop

Posted by Greg On October - 10 - 2009

Recently I have seen many HDR images that were too exaggerated, making them completely unrealistic and in some cases even unpleasant to watch. Programs such as Photomatix make it very easy to create HDR images but they are also tend to lead people to create very exaggerated HDR images, maybe because it is very easy to accomplish in these programs.

I have nothing against using HDR techniques in creating artistic imagery, but I would like to remind you that the original intention of the HDR was just to increase the dynamic range of the photograph.

However with a little knowledge of Photoshop, you can do that – you can create an HDR image that will look very realistic but still show all the detail that you want it to show.

I created a pretty simple tutorial that shows how to manually create HDR image in Photoshop. In this tutorial I used two photos taken at the same location (using tripod), one exposed for the bright sky and the other one exposed for the darker lower part. Though I used only two photos, you can use as many photos as you like revealing detail in any part of the scene according to your preferences.

There is one point of this tutorial that I would like to stress out one more time – use large brush with soft edges and opacity around 50 to 60 percent. It is important so that your final image won’t have these “white glow” edges that can be seen in so many HDR images.

If you are new to the whole HDR thing, you can read my previous posts on the subject: HDR – Introduction and What is Pseudo HDR image?

If this tutorial helped you to create your own HDR images I would sure like to see them! But if you don’t have Photoshop, but still want to create HDR images, you might want to try Photomatix.
