Speaker at “Photoshop day”


I’m getting slightly nervous because in about three weeks I’ll be one of the speakers at the highly acclaimed photoshop day and I’m there to talk about three layered photography and simple editing – most likely show a different workflow for us that uses external developers. But still I want to make it interesting for the audience. It will be held in Göteborg, Malmö and Stockholm.

Could you guys help me with short simple topics that could help me bring “me” into this day? :D PLEASE! What would you like to know if you were sitting in the audience?

EDIT! First, I want this post to be first so I can get some more input. Thanks for email everyone (you know who you are). Also, today I received my long awaited SD15 (the REAL one) and I’ll start shooting with it from today. First tests shows really nice IQ and a perfectly aligned mirror. (my pre-version was slightly off). I also finally got myself a trigger and will be able to do long exposures. jaij!

About Carl Rytterfalk

Welcome to my blog! I'm Carl Rytterfalk, a swedish photographer who loves everything that is interesting in the world of photography. In 2002 I fell in love with the three layered Foveon sensor and has since then been an addicted user of Sigma cameras. Though I use Canon and Nikon as well. :)

    - How to get the most with your camera before download to computer,best histogram possible,use of external lights….
    – The real workflow with an special emphasis in “Sharpness”.
    – Basis techniques with layers(adjudsment layers,improve the image with two photos using camera raw and photoshop).
    – Make a perfect selection using rgb layers.
    Or just how to get your stunning and clear photographs.Maybe is that what the audience would expect of that conference.
    I don´t know much about photoshop I develop my photos with SigmaPro 3 and I give the final touch with Lightroom 3,but I would like to know that kind of process with Photoshop.

  2. tbone, very good pointers! I think using external flash the “easy” way – use of histogram instead of light meeter. And perhaps also the importans of sharpening before print – or web – etc.

    Light. How to think about light, how to use shadows in order to create depth. Where should sun be and when can external flash be used together with sun. hmm..

    Perhaps also something about focal length and depth – Bokeh. Why it’s important to change the kit lens to something else. :)

    I will also show How I use LR3 for post and I think a thing or two using PS5. But I think most of the things I will show will be inside SPP and LR3 + some pointers of how to make nice shots the easy way.

    If I were sitting in the audience I would like to know how to decide when to change a color shot into monochrome. There is a fine line there and I don’t really understand where it is drawn.

  4. Tom Schum, That is another tricky thing. Many times I feel it’s an easy decision – and I do it often when I feel that the color version isn’t great in terms of – colors. Could be Noise. Could be distracting colors – things that takes away focus from the main object.

    Or as some recent shots where I used ISO50, then the dynamic range is much greater using monochrome white balance in Sigma Photo Pro – and suddenly a broken shot will look amazing.

  5. Retro says:

    Hardly known by many people is not only working with layers, but specially using the existing “layer modes” sophisticated.

  6. Retro, any specific usage you’re after? Or just, if I use – then how do I use it? :)

  7. Hans says:

    Two things come to mind:
    1. Talk about the fundamental differences between Foveon vs. Bayer technologies, I think a lot of people do not know much about the Foveon sensor. Touch on the differences in editing a bayer vs. Foveon image based off of their characteristics.

    2. Talk about the importance of shooting and developing in RAW. I think there is a lot to cover there.

    I know you are busy but will you be doing a video review of the sd-15 much like the sd-14 one here?:

    I would love to see it! Thanks!

  8. Hi Hans, I will definitely talk about the Foveon sensor vs Bayern. :D And yes, There will be a SD15 review. I got the “real” camera today so one of these days. I need to find a video camera and a camera man. :)

    I have lots of photographic equipment but no video camera. duh.

  9. Retro says:

    “Retro, any specific usage you’re after?”

    – For example making a collage overlaying two pictures.

    – Or the correction of a selected part with a modified version (more contrast, lighter, darker, partial sharpening etc.)of the original picture.

    If you are talking about 3 layered photography you should show examples where 3 layered photography is better.

    0) Open your session with a slide show as a teaser, then jump into with your speech

    1) Explain that beside the matrix sensors we all use in our cameras there is a niche technology which is a more natural approach to record pictures.

    2) Explain that there is a pixel defined picture for the 3L sensor where matrix types are always relying on interpolation
    -> Explain that in the matrix type sensor there are actually 4 planes which differ by 1 pixel and need to be moved by a sub-pixel spacing, e.g. to the center (x) of the quadlet (RGGB)
    G R
    x
    B G
    -> Show an example of pixel sharpness of 3L photo

    3) Explain that the main purpose of the Antialiasing filter is color moire which is immediately visible and very disturbing
    -> Show an example of color moire
    -> Show an example of moire in Foveon pictures after explaining in real world pictures it is a) seldom and b) becomes normally only recognised when intensively looking for it.

    4) Avoiding errors introduced by interpolation and weakening high frequencies by means of Antialiasing filter, then applying sharpening filter
    -> Show side-by-side examples of chaotic structures like hair and foliage. In Foveon pictures there is no inconsistent sharp-much-sharp transitions (but you have to use SPP as a RAW filter to clearly see that)

    5) Show examples for better color separation in full spectrum light
    -> Show how clearly close colors saturate with different colors
    -> If you have a picture of sb with a brown teint but is also red in face because of recent excessive sun-bathing show what spectrum of colors is in this picture by moving the light temperature slider in e.g. LR (I don’t have any idea how Bayer camera recording compares, but a X3F recording is – hmmm, shocking!!!). What you are doing with this example is color transforming the picture into a range where our eye separates colors better.

    6) Bring an enlargement with you and explain that it compares nicely to matrix recordings with much higher pixel count. The reason is the information stored is about the same.

    7) Show how 3L compares to matrix today.
    -> There is only one manufacturer (less competition in 3L, limited resources, does not have access to latest technology /Sony, Canon have their own Semiconductor manufacturing)
    -> Because of that, in the moment less suitable for high ISO and sport photography)
    -> No movie capability (Though sensor could have supported movie years before the competition)
    -> Step to FF expensive to impossible because accuracy needed stepper cannot give today
    -> Complete lens sortiment
    -> No professional service from Sigma, bodies not on >= 7D levels
    -> Using advantages of 3L and matrix to substitute for each weakness as of today

    8) Finish with slide show
