What are people's views on prop blur when displaying a model mid air? Good or bad? What techniques have you found best?

I'm unconvinced but all real life photos seem to have this so.is it something i should build into my models?

For an in flight model, I just cut off the prop blades. I don't think the prop blur products look realistic.

If you're going to try something, I think this method looks the best:

"Prop blur" is an artifact of high prop speeds and low shutter speeds. It wouldn't exist if the shutter speed was high enough to "stop" the prop. Which suggests that there is a technical argument for saying "no blur".

However, it also means that you can, if you want to model a photographed moment, make a sound argument for semi-transparent segments of a circle (number and colour(s) to suit blades), or even mostly transparent discs (eg clear sheet painted with Tamiya smoke and clear yellow edges for most WW2 types).

Must be my low brain speed that causes it to blur when I don't have a camera.

I'm with Ratch on this one. It's not something that looks 'right' in my opinion. As an alternative, what about motorising the prop?

@dancho @Ratch - https://en.wikipedia.org/wiki/Persistence_of_vision explains this fully: TL;DR version is that your brain only processes images at about 25 frames per second, and prop blades make a significant arc in that time.

You misunderstand me, I do not like the modelling simulation of the effect (so I don't do it) :roll:

I find neither prop blur products nor chopping the props off looks good for inflight aircraft. Chopping them off just looks like the aircraft has lost them and is about to take a nose dive and the blur disks remind me too much its a model.

Big NAY!!! Prop blur is not for me, completely unrealistic a lot of the time and unconvincing, leave propeller/rotor blades where they belong, attached :nod:

Prob blur... a definate no from ne ...looks naff ...if you remove parts for an effect then your model is incomplete....but then each to their own way of doing it ...its your model build it the way you want....i build mine with the blades attached

I would make the distinction between display and diorama. When I've seen wheels up models displayed on stands or hanging from 'string' they look fine with the the prop as is; but for me dioramas look static without blur; it has to be done well though, and I guess that's more subjective.

As all my planes are meant for Static Display, then static props but if I was to use them for wargaming then I´d consider adding the blur effect

All my models are built 'on the ground' but I often take photos of them 'flying'. When I do, I blur the props using photo editing tools as the lesser of two evils, i.e. they would look daft with static visible props. but the blur effect can be a bit unrealistic as well. But then I often spoil the effect of 'flying' by leaving the pilot out!

No.

The way I see it if your model is depicted in flight, it is representing the model frozen in time. The aircraft is static in the room so the props should be static on the aircraft.

At the risk of being controversial and stir the pot, but I don't regard an 'in flight' photo as showing a model frozen in time with everything static. I regard it as how one might see, i.e. actually see with human eyeballs, the aircraft in flight. One does not see static props when an aircraft is in flight. They are either blurred or even invisible to the naked eye. The aircraft is moving so the image should try to capture something of that movement, even if only by showing it banking, diving, climbing, whatever. Adding some exhaust or wing edge effects can also help create the illusion of movement. Taking a photo against a cloud background is something that Howard Hughes discovered, rather than filming in clear blue weather conditions so I usually try to do the same. All of this, of course, is specific to taking photos of a model, which may not quite be what the original question was asking (it said 'displaying' rather that photographing).

I'm building an old Monogram P-51B and I cut the prop off for an "in flight" look.

The funny thing is, sometimes I'd swear I could see just a hint of prop blur...

Is that being overtired or is it a scotch, vodka, tequila (tick preference) induced prop blur Dancho :joker: :joker:

It's the ghost of prop-blurs yet-to-come!
