August 2022 – PauloBizarroPHOTOBLOG

I recently took some time out with the family in my house in Longueira, in the Alentejo coast. During a couple of weeks, we relaxed in the beaches of the region (Almograve, Odeceixe, and Arrifana), enjoying the sun and the ocean. Granted, August is not my favorite month to spend time there, due to the crowds of vacationers that arrive during the summer season. Still, the beauty and pristine character of these beaches and the isolated interior hills, remain relatively unaffected by the many visitors.

Of course I had to make some time for my photography, walking along some of the coastal paths, and visiting the numerous secluded small bays and inlets, where hardly anybody goes. On one of such occasions, I decided to walk the couple of km between Almograve beach and the small fishing harbor of Lapa de Pombas. Within such a small distance, there is an amazing variety of isolated beaches, most of them framed by the rocky cliffs and covered with pebbles. I like to visit during low tide in the late afternoon, close to sunset time. This gives me about 2 hours of photography when the interesting light is falling on the colorful and folded rock formations.

I usually do not write much about gear, but this is a good opportunity to mention one of my favorite lenses, the Fujinon 14mm f/2.8. This wide angle lens is essential to me, because I find it ideal for my photography, including the seascapes of this area. So, all the photos that follow were made with this lens. The weather was overcast, with some fog banks coming and going, which can be both positive and negative. It is positive, because the fog acts like a giant light diffuser, softening the light that falls over the cliffs and the sea; but is also negative, because it results in bland and uninteresting skies. As such, in most of the photos I have chosen to exclude the sky. I have also used a 10 stop neutral density filter to add an extra dimension of softness to the water, which complements nicely the overall mood of this quiet afternoon stroll.

Dark rock layers have been smoothed out by water erosion. Same rocks above the water line are still sharp and edgy.

During low tide, it is possible to walk down from the top of the cliffs to the beaches, where there are many tidal pools, eroded rock formations, and folded geologic layers. A few minutes before sunset, the fog lifted for a while, and a warm light descended over the area, adding an almost otherworldly dimension to these scenes.

While walking around in these beaches, it is important to be careful, because the smooth rock surfaces are sometimes slippery due to an algal cover. Plus, pay attention to avoid twisting an ankle while walking over the pebbles. Other than that, if you visit these places, you will have a wonderful time. I know I did.

Summer is an excellent time to be out in the field photographing the night sky. At a dark site location during the new Moon, and with clear skies, conditions are good to make some interesting photos such as star trails and the Milky Way. It is better to choose a place as far from light pollution as possible, so you have a clear and detailed view of the stars. In the region of Odemira, I like to go to the rural interior, far away from the coastal villages. I like to go to an area between Odemira and Sabóia that I know from past experience to be quite dark. There is a small hill with a ruined farmhouse that faces south, so it provides an interesting foreground for a star trail. Below is a photo that I made a few months ago.

According to light pollution maps, this location has a classification of 3 on the Bortle scale (rural sky), which means that there is some light pollution in the horizon and the Milky Way’s complex structure is visible. Below you can see the map with the classification.

I arrived at the location with enough time to set up my tripod and camera, selecting a composition featuring the farmhouse in the foreground. My 14mm wide-angle lens is only f/2.8, which is not ideal for night sky photography. Still, with some careful workflow, the results can be good. My camera has an intervalometer, so it is easy to set it up for shooting a series of consecutive frames to be assembled later in Sequator, the software that I use for building the star trails and stacks. I normally shoot Raw, f/2.8, 30 seconds, and ISO 1600. This works fine with Fuji X cameras.

For star trails, it is important to turn off the long exposure noise reduction, as that would take an extra 30 seconds dark frame after each shot, doubling exposure time and introducing gaps in the trail. Then, you just select how many frames you need to achieve the total exposure time you want your trail to have. I normally aim for about 1 hour total time, as that provides a nice circular trail around Polaris.

After finishing the star trail shooting, I also took some photos of the Milky Way, to stack later in Sequator using the “align stars” option. Usually I take between 6 and 10 photos for each stack. If there is some “land” in the frame, ground features will be blurry as result of the Earth’s movement.

For comparison, the following photos are single exposures of the Milky Way over the surrounding countryside. These do not have the blurriness of the land features (such as trees), but have less light gathered, compared to the stacked ones. I like the results from both options.

I always enjoy photographing the night sky, and look forward for the next opportunity to do so.
