Kawallito Posted September 14, 2022 Share Posted September 14, 2022 Hi there, Im trying to create the effect of motion on my car by making the wheel appear to spin using the radial blur tool. However the tutorials I find are all when the car wheel is facing completely straight so the effect is easy to apply when you choose the center of a circle because the wheel IS a perfect circle. Now the car I'm trying to give motion to is on an angle so the wheel is turned making the wheel into an ellipse. If I choose the center of the ellipse the spin effect is weird because it's not a perfect circle. Its like the entire ellipse is spinning around the center. I want it to spin WITHIN the ellipse. How do I do that? Thanks. Quote Link to comment Share on other sites More sharing options...

R C-R Posted September 14, 2022 Share Posted September 14, 2022 Have you tried first making an elliptical 'marching ants' selection with the Elliptical Marquee Tool & then applying the radial blur to that? You can drag the center of the blur around on the canvas to center it & set the angle to whatever you want. It is far from perfect but feathering the marquee can improve the look somewhat.

smadell Posted September 15, 2022 Share Posted September 15, 2022 Here's an alternative. Not perfect, but it does allow you to re-shape the radial blur. (1) I started with a photo, similar to the one you used. (2) I duplicated the photo, and applied a radial blur, centered on the middle of the tire. (3) I clicked the "Merge" button, making the radial blur a destructive edit, albeit on a separate layer. (4) Since the radial blur is now a part of the pixel layer, I can choose the Move tool and "squeeze" the blurred layer inward, so that the shape of the blurred tire matches the elliptical shape of the original. (5) Now, it's just a matter of applying a mask to the blurred duplicate layer, so that only the tire remains, and the rest of the non-blurry original is seen. (1) The original (2,3) The blurred, duplicate layer (4) Squeezing the blurred layer inward (5) The blurred layer, masked to reveal only the tire.

firstdefence Posted September 15, 2022 Share Posted September 15, 2022 Use the Smudge Brush, in a clockwise movement. I set the Brush to Strength: 75% Flow 10% and brush size is up to you.

JimmyJack Posted September 15, 2022 Share Posted September 15, 2022 Possibly try this? It's your car right? Take a separate picture of the wheel directly from the side (try to match lighting etc). Add the blur to the non perspective image and THEN resize/skew it. The effect will distort with the image. Do the tread section separately. smadell, Kawallito and Lisbon 3 Quote Link to comment Share on other sites More sharing options...

Thanks for the reply. Yes I have tried that. It still makes the blur in the incorrect direction. On 9/15/2022 at 1:06 AM, smadell said: Here's an alternative.

Unfortunately this method still make the blur in a circular motion instead of an ellipse even tho the effect is shaped into an ellipse and not a circle. Below is what is happening: What I would like is below: On 9/15/2022 at 4:02 AM, N.P.M. said: Why not select the wheel>duplicate>apply the live blur filter>use perspective live filter to fit the direction Thanks for the reply. This method still gives the effect as circular. On 9/15/2022 at 5:13 AM, firstdefence said: Use the Smudge Brush, in a clockwise movement. I set the Brush to Strength: 75% Flow 10% and brush size is up to you. Thanks for the reply. This method does give the correct illusion! Its a different method of thinking about it. But I really hoped affinity photo gave a way to do this effect as easily as Photoshop does. On 9/15/2022 at 1:49 PM, JimmyJack said: Possibly try this? It's your car right?

This method aslo works and looks great but I'm planning on doing this with other cars as well where I won't have the luxury of taking a separate picture from the side. But this is the look I'm going for. Quote Link to comment Share on other sites More sharing options...

Lisbon Posted September 17, 2022 Share Posted September 17, 2022 I would use live projection before applying the blur. The only problem is that I can't get a perfect circle. Any tips on how to create a better perspective grid? I tried following the shadow lines as a reference and that was it.

It wil, also work even if the default shortcut(s) are changed & for Windows where (I assume) CTRL is used rather than CMD. (Just mentioned for consideration for those making instructional videos.)

That method worked really well for the front wheel. Would it work that well for the rear? I feel like it's on too much of an angle to be distorted I to a circle and apply the filter. Would love to see how you would approach it. Thanks! Quote Link to comment Share on other sites More sharing options...

After the filter is applied to the rasterized copy selected from the original image, I think you should be able to shear it to get a convincing if not perfect effect.

thomaso Posted September 18, 2022 Share Posted September 18, 2022 "Shear" is a kind of bend or tilt. It is the lower right option in the Transform Panel ("S") for numerical input and can get manually dragged with the Move Tool (placed next to one of the object's bounding box centre handles). https://affinity.help/publisher/English.lproj/index.html?page=pages/ObjectControl/rotateShear.html?title=Rotating and shearing objects Kawallito 1 Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...
