How can I create this effect?

18714_Fruit-Ninja-iPad-App-Review.jpeg

I want to create this because I want to make it look like there is a knife cutting fruit,

This is what I have already:

    A couple of general comments.

    It would be better to show the fruit inner surface not just every fruit side on. It would also be better to start with a higher resolution image.

    However starting with your image - I used layers to build up an example of what you could do:

    Draw the sword with the pen tool set to shape and fill the shape with a gray gradient.

    Then use layer styles to add a bevel edge and inner glow.

    Copy the fruit - turn upside down and clip to the sword layer so that they are only visible in the sword and appear to reflect

    Copy the sword and use liquify to drag the back edge and a mask to fade it - this will suggest some movement

    Add some faded strokes with a white pen and some "cross" highlights with the brush

    Copy the top half of your image and place it above the sword so that it appears to cut

    Finally a few water droplets - just hard brush strokes on an empty layer with the layer style set to give two inner shadows (light and dark) and a radial blur using the zoom setting to suggest movement.

    Here are the layers I used to give an example.

    If you want detail on any particular layer let me know.

    Above all - have fun !

    Thank you very much for this explanation.

    I never thought that someone would take this much time to create what I want and explain what he did.

    I can really do some stuff with this advice and I'll try to use it the best way I can.

    By the way, how would I make it look a bit more realistic by adding inner fruit. Should I just look for images for the inner of the fruits and reshape it a bit to make it look like it's flying towards us?

    I really appreciate your time and answers!

    Yes, if you have an image of say the inside of an orange - warp it so that it is just visible and combine it with your image. If you look at the top image you posted, the inside of the apple is visible.

    If you want to make your image look more realistic  - the orange and pear in your example would be tipping slightly whereas the banana is still being cut so is OK side on.

    Like I said - have fun with it. Experiment and, If you get stuck, shout out .
