I am a relatively new photographer, having been at if for only a few years. I chose Canon gear when I finally took the plunge into DSLR. I am an avid hobbyist now, and love everything about photography, from the gear, to the science, to the art. I spent years reading about the technology and photography theory, so I am very well versed in the technical aspects of photography. My artistic skills are moderate, but improving. You can see my work @ the following sites:

My interests lie primarily in nature photography:

  • Birds
    • Songbird Setups
    • Shore Birds & Waders
    • Raptors
    • All others
  • Astrophotography
    • Moon
    • Wide Field
    • Deep Sky
  • Landscapes
  • Wildlife
  • Floral Macro
  • Insect Macro
  • Abstract

I currently use the following gear:

  • Cameras
    • Canon EOS 7D
    • Canon EOS 450D (Rebel XSi)
  • Lenses

comment How can I make the text in this photograph of an ancient column more readable?
...that I used it to produce the results in my answer with nothing but Photoshop and all of it's filters and other tools. In order to achieve a good result, I needed to know that Photoshop used math behind the scenes, know how that math worked, so I could employ each tool or filter effectively, etc. I also have an extensive collection of third party filters and action sets that allow me to do pretty much anything with Photoshop, from advanced deconvolution and deblurring to even generating FFTs. One doesn't need specialized software when they have a tool like PS (or even Gimp.)

I'd point out that an FFT is a useful analysis tool, and analyzing images is important in quite a number of fields, including your average photography, astrophotography, etc. But FFT isn't the only "algorithm" involved in image processing. Every single filter, every single tool, that Photoshop has to offer functions because there is an algorithm, a mathematical algorithm, that makes it function. Without the math, some of which, for some filters, is quite complex, there would be no Photoshop at all! I also clearly believe that Photoshop can be a very effective tool for image analysis, given...

I think it is mistaken to assume that FFT isn't well understood in the image processing world. I am also not even sure it is safe to say that amateur and family photographers make up "most" image processors. I'd say most amateurs simply point, shoot, and share, without processing a all. Of those who DO process, I think there is quite a significant presence in the scientific, medical, industrial, and more advanced photography populations who do clearly understand what an FFT is. As for photoshop, photoshops tools are all ALGORITHMS, so I think it is quite inane to think PS is NOT mathematical!

+1 for the laugh. :) One thing I'd note...by painting in what you THINK the letters are, you are quite possibly reproducing them incorrectly. If the intent was to truly discover something about the text, that couldn't be seen without processing the photo, drawing in some lines with MS Paint isn't really going to reveal anything.

Thanks for the edits and improvements. I think the question is great now, so I've reopened it.

comment How can I make the text in this photograph of an ancient column more readable?
The goal was clearly stated. "Is there any way I can manipulate the image to make the text stand out and be easier to read? ... I don't care if the background color gets manipulated, I just need the text to be easily visible." That is a VERY UNambiguous request. No further explanation is needed to understand what the goal is. The goal is to make the text readable, regardless of what happens to the rest of the image.

Just to offer an alternative approach guys...sometimes it helps just to answer the question posed, rather than critique the purpose or point of asking in the first place. ;)

comment Grainy/low quality pictures - how to stop?
@MysMelody: Well, regardless of which camera you are using, I think my point still applies. If you really want truly better IQ, a better camera is the logical place to go. ;)
