    Fake tilt-shift photo with gradient blur?

    dhogue94 Level 1
      I came across these simple tutorials for Photoshop that imitate tilt-shift photography by using a gradient blur (the lens blur effect), masking, and curves.

      Is there a way to create this same effect with Fireworks CS3? I've been trying to play with masks, gradients, and blurs, and I just can't seem to get anything remotely similar.

      Thanks!

          I have a few tutorials that use Fireworks to create photographic
          effects on Community MX. The link below goes to the search results page

            Off the top pf my head, two ways:


            -clone the image twice, so that you see a top clone, a middle clone, and
            the original image in the layers panel.

            -use the marquee tool set to feather 10 pixels to select the portion of
            the image you want to remain sharp.

            -once the selection is made, choose Select > Invert Selection, and then
            Edit > Cut.

            -apply a Gaussian blur (I used 2.00) to the middle clone

            Alternatively, if you want to do it non destructively,

            -clone the image twice and cover the clone with a rectangle

            -fill the rectangle with a horizontal liner gradient of white - white -
            black - black - white - white.

            -select both the rectangle and the clone and choose Modify > Mask >
            Group as mask.

            -apply a blur to the middle clone.

            -adjust the position of the colors in the masking gradient as necessary.

              Linda,

              Thanks! I'll try this technique this evening and let you know how it works.

                You can't get this effect in Fireworks with the same level of realism and precision as Photoshop because of two main problems:
                1) Fireworks has no blur type that creates lens blur type effects. Gaussian blur creates a different type of blur that looks much smoother.
                2) You can't create a gradual change of blur amount using a value ramp, like a gradient, like the Lens Blur filter does in Photoshop. If you put a clone over top and blur the clone, then mask/erase parts so the original shows through, you'll notice the affect looks more like a haze or mist is over top of your original image. This is because the blur doesn't gradually increase, there's just semi-transparent blurred stuff over top.

                Lens Blur is a filter I've wanted in Fireworks for awhile.

                If you don't have Photoshop available to do a real Lens Blur, you can get a Fw compatible plugin to do it:
                http://www.dofpro.com/

                Or you can try the workarounds suggested. Here is my take on the workaround options (which I do use often):

                1) As suggested, create a clone over top, blur the clone with Gaussian blur live effect, then mask or erase parts of the clone so the original unblurred bitmap shows through. As I said, this doesn't create convincing, gradual changes in amount of blur, but it may be acceptable for what you want.

                2) Do the same as above, but use several steps. In other words, create say 4 clones (so you have 5 identical bitmaps). In the layers panel, add increasing amounts of blur on bitmaps... so for example the original has no blur, the one below it has 1 radius gaussian blur, then next one below has 2 radius gaussian blur, the next below has 3 radius gaussian blur, then last has 4 radius gaussian blur. Then you mask out more and more on each bitmap, so the bottom most-blurred one has no mask, the one above has a wide mask, the one above has a less wide mask, the one above has an even less wide mask, and the final original one has the smallest mask. Yeah, it's kinda crazy. :-)

                3) The third option is to use the blur tool. The blur tool will let you get more gradual blur changes, because you can simply scrub over areas longer to slowly increase the amount of blur. The problem is that it's harder get precise value changes from one area to another since you are doing it by hand. Also, the blur tool has a tendency to darken the color for some reason.

                Here's an example PNG, which uses all 3 techniques on different hidden layers:

                Hope that helps.

                  Aaron,

                  Wow! You cranked that out in less time than it takes Windows to boot up...

                  Actually, I do have Photoshop CS3 and access to the Lens Blur effect, but I'm always looking to expand my Fireworks skills, and since I spend much more time in Fireworks than I do in Photoshop, I thought this might be a good challenge for me. I had the same idea you presented about using multiple progressive masked bitmaps, but I wasn't able to pull off the execution nearly as cleanly (mostly because I don't use masks very often, and I'm really pretty klugey at it...)

                  Thanks for the sample file - I'll be taking this apart and trying to learn from it.

                  Dave

                  PS - My hand is not nearly steady enough to try doing this with the Blur tool, but I am completely impressed by your accuracy and dexterity.
