    New Photoshop Wiki

    Dear all, may I introduce my new Photoshop Wiki: http://opticalenquiry.com/photoshop/ I wrote it to support my digital painting course here in Singapore's School of Art Design and Media. It covers such elements of Photoshop as are useful to the digital painter. It also dips its toe into some...

    Help needed on research project. Can Photoshop do this? We think not.

    Well well, this is a fascinating result. Lab 'Man from Mars' We were aware of this approach. It is interesting and can indeed shift hues. However, its results are unpredictable. What happens is that it can expand the hue range in some cases but only at the cost of compressing it in others...

    Help needed on research project. Can Photoshop do this? We think not.

    I agree, our results are not always pleasing. However they were made with an engineering community in mind and their main point is to demonstrate the technology. More subtle changes would not have made the point as clearly (to engineers). The big issue is explain to computer vision people the...

    Thanks. None of us are photographers so our results suck somewhat. More suckiness here: Results of Hue Stretch

    Thanks. It is good to know that it is a challenge. None of us yet are anywhere near thinking of this as a comercial venture. We we be looking for people to play with a prototype as soon as we have one (our current version only works within a specific developer environment).

    It is clear that I have not explained myself very well. Apologies. Here is a schematic showing what I mean by hue contrast compression and expansion: Here also is some more of our results. Results of Hue Stretch Essentially, we are taking a discreet slice out of the hue spectrum and...

    Help needed on research project. Can Photoshop do this? We think not.

    Dude... I'm just a joe. Self taught also... and still learning :) As our process is a filter, unwanted color adjustments on non-target regions are bound to appear. One of the problems with photographing such things as jungles, desert floors, rocky terrain etc is that the camera is not very...

    Help needed on research project. Can Photoshop do this? We think not.

    Thank you greatly for your feedback, My understanding of Photoshop's ability to manipulate hue is this: 1. That a hue value can be made to seem more intense by editing its brightness and/or saturation. 2. That the hue values of an image can be cycled i.e. the color wheel rotated. 3. That a...

    Dear Photoshop Guru forum users, My name is Martin Constable and I am research professor at Nanyang Technological University in Singapore. I have a problem that, hopefully, will present something of a challenge. We are working on the topic of hue contrast, which is something that we feel...

    Removing person and adding to a different picture

    It all depends on what images you are using. If the foreground (figure) has been shot with the specific intention of laying over the background, then it is relatively easy. You will need to separately match: edges, color and grain. Edges: use a layer mask on the FG and paint your unwanted...

    Blending photo edges for collage

    Be warned: the danger of using the mask is that one is always accidentally painting on the RGB image by accident. To check the content of your mask option click on it.

    I need help making a sillouhette of this image.

    You can trace the profile of the car by hand using the pen tool (best for smooth forms) or using Select / Color range. You will need to tidy up the result a bit if you use the selection route. Criticism of your design? I would recommend against mixing so many fonts in one design. Maybe use a...

    What photoshop program will do this?!?

    Yes. There are almost too many ways to do this. The coloring on the lips and eyes was probably done with a layer blend like Color or Multiply. The extreme two-tone of the face was probably done using color adjustments like Curves or Levels.
