Rusty rocks at Garrettstown Strand (South)

Scroll down to content

Iron-stained folded carboniferous sedimentary rock of the Cork Group

Not all the rocks on Garrettstown Strand have the nuanced colouring and delicate integral patterns shown in earlier posts. Some at the southern end of the beach are full of iron that has weathered into interesting hues from orange to purple. The rusty-coloured rock strata are often re-shaped into massive curving folds: seen as cross-sectional in the cliff but resembling a series of frozen waves on the shore. Many of the beach stones at the base of the cliff are derived from the same dark dramatic rocks.

  1. Thank you. I was actually a little disappointed with the pictures. The rocks were very dark, and there was a lot of white cloud cover, so the photos ended up having a bit too much contrast. I didn’t really feel that the images did the rocks justice. That’s the problem with being a natural historian first and an amateur photographer second. I just don’t have the necessary techniques sometimes to capture with the camera what I see with my eyes.


  2. Cant say how they compare to the scene at the time, but on their own merit, I love them. Those high contrast siutations are difficult. Unless the horizon is straight, filters are no use. There are ways round it with softwar, especially if you shoot RAW files, or take different exposures for the rocks and sky. Some software will combine them for you, but it usually looks overdone I think, or you can do it manually, but its a bit of a chore. No perfect answer unfortunately.


  3. Thank you for the feedback. It all sounds very complicated. I think a compromise might be a different camera that might be better-suited to what I do.


  4. A better camera will probably give you a wider dynamic range Jessica, but the low end DSLR I use would still have the same problem. Some of the more recent ones have a HDR function built in but I’m not sure how effective they are.


  5. I don’t think I could manage a DSLR but have been looking at other makes of bridge camera than the one I have at present. Searching through the various specifications, there’s an amazing range of capability. It’s not easy making a choice to exactly suit my needs but I have narrowed the list down to just a couple I am really interested in.


  6. It is amazing what’s available now, although its a long time since I looked at developments in bridge cameras. I would always lean towards the DSLR though – wouldn’t be much, if any difference in price in some models now, and they all have scene modes to start with. Looking at your photography, I’d say you could easily manage one, better than many people who have one. Its true what they say though, its the photographer not the camera, and I’ll be looking forward to your shots whatever you choose.
