    I need to select only the text

    I need to select only the text from the image at the bottom which I have scanned as a displacement map.
    I have done the selection before but now I want to do it again more precisely.
    This was before when I made my 1.st DM with a more or less clumpy selection of the text

    I need to select only the text

    But now I want to use another text and I have been struggling to get it over a transparent background and save it as a Photoshop file.
    A *.psd file in fact.

    I do have tried with the magic wang tool and refine the edges but I have been struggling for so long now... May be if I would select through the channels...

    I need to select only the text

    Who can give me a tip please ? Thank you

    After working hard on this I did by myself.
    This is just a test.

    Antonio it looks like you have solved the problem. You haven't said how you did it but that it was hard work. This is a way which may be simpler. It doesn't need any selections at all and uses only two blending modes. I took your text and blended it with one of my photos to get this:

    I need to select only the text

    So if this is what you were trying to do here is the method.

    1. The scanned text: Duplicate the background layer and set the blending mode to Overlay or soft light or whatever in that group of blends gets the best result. That is to clean up the background. I can't tell from the small image you posted if the text will still look OK but with a good scan I think it should. Flatten the image.

    2. With the Photo open, drag the text file on to it to create a new (text) layer. Position as required and set the blending mode to multiply.

    And that's it. Two blends and you might not even need the first. It works because multiply blend kills white, so the white base of your scanned text becomes transparent.

    It should work in any editing program with layers and appropriate layer blending modes and I thought it might be of general interest.

    Thank you John from Cambridge UK
    Nice of you to have all this trouble now that I have solved the problem.
    And no, that is not what I wanted to do or I have misunderstood.
    -
    When I posted I had been only "around" a video which method was a little different from the way I did it.
    Surfing a bit - Google has everything, even bad, very bad infos as well as good ones, it is true - I landed on a video by a Brazilian. It was not very good but good enough.

    I then followed his instructions and I came to what I wanted.
    Now I will tell you how I did it.

    1. I opened file Car and adjusted it in ACR
    I need to select only the text
    2. Image/Mode/8 bit
    3. Rasterize layer
    4. Save as Car 01.tif for security reasons.
    5. Image/Duplicate = Car 01 copy.tif
    6. Image/Adjustments/Desaturate
    7. Image/Adjustments/Levels (brutal change)
    I need to select only the text
    8. Filter/Blur/Gaussian Blur (50)
    I need to select only the text
    9. File/Save As Photoshop File with the name Map
    10. Close Map.psd as well as the duplicate
    11. Open file Text.*
    I need to select only the text
    12. Drag this file over Car 01.tif
    13. Adjust accordingly to wish
    I need to select only the text
    14. Bending Mode to Multiply with layer text selected
    15. Filter/Displace (50 and 50 for values) twice, (Command F) with the Map file previously saved
    16. Indeed i duplicated this layer to increase the density of the Multiply Filter.

    I hope I have not missed anything. In fact, I was doing and writing here at the same time.

    I need to select only the text

    Now I wonder which diference does it make to blur more or less

    Hi Antonio

    After I posted last night I had another look at your first composite and very nearly wrote again. I thought you could have used multiply as the result was so clean. Then I thought maybe this property of the multiply blend is still worth drawing attention to on the list, so I left it. (I have a vague feeling it is mentioned in one of Sean's tutorials but I could be wrong).

    Whatever, you got a good result and reminded me about displacement maps, which I must take another look at.
