hello,
after so many years with FF i have now thought of one thing tbat I never cared about or thought about it
when you feed source images to the bomber it will use them to create particle with these images, but they are much smaller than the original size of the input, and If you he reduce them even more wih the settings of bomber it may be very tiny.
AND also considering this that you can read this on the FF features page

| All filters in Filter Forge are generated procedurally and don't depend on external bitmaps; therefore, they are resolution-independent. You can render the same filter in any resolution without losing any detail |
So now I wonder
How relevant is the resolution size of the source image input into bomber for using as particles?
is the same to use a 300x300 image, or 600x600, or 3000x3000 for using them as particles inside bomber?
What would minimum size would be needed to have good quality results from bomber particles?
If filter forge forge is procedural and resolution independent, How are processed the input source images into bomber to be used as particles?
Thanks |

Humm.......
My opinion is that if you you use an image as the base of your result, the bomber or any other component applies the effects the same way, no matter if the image you have chosen is big or small. I believe that there are clearly limits of size : if your image is really very tiny, the result will look confused.
Instead, if you use that image as particle, because the particle is resized, depending on the resolution of the image, the result may change.
But this is simply my opinion.
I think we can easily try with the same image but with two completely different resolutions. So we can see the difference.

The question is only about images loaded in bomber as particles, not as base of the design or as mask, or any other way
It is suppossed that if you use a 640x480 image as source for particles, you would be able to make then any size of result
i am testing it

It is a question that is similar to "what size should I make my textures at for 3D imaging?"
The theoretical answer in the context of 3D imaging is: "Depends on how close to the surface you are going to put the camera."
My theoretical answer in the context of the Bomber is: "Depends on how large the largest output of a single particle will be."
The real answer is: In actual practice I have never had an issue with it. Having the source images large doesn't significantly affect the performance of the filter, so I have never once bothered to shrink a single image for Bomber use.

Yes, as ThreeDee said, if the bomber will produce only small particles, the resolution of your picture should not affect the final result much.
If the bomber will produce rather large particles, it could happen that the particles look like pixelated or anyway in low resolution.
I remember to have seen bad particles results one time.
It happened using a very small image.
But already the original image was not good, so it's not surprising that the bomber could not get a nice result.

Thanks Ramlyn and ThreeDee
i think that you are right about the answer

I also thought something similar as you, but the reason to ask, was that it is told that the result is resolution independent
Will have to test it and see it really how is done by making a real test, sorry that I have not had time to do it yet
i do not mean in any moment to reduce any image, is just only that perhaps you may small objects images isolated in transparent PNG of about 200x200 pixels that could be used with good result |

I have tried to test this, but have made it wrong I think, as I have used 600x600 source images, and to get a result with bomher where a particle should be higher than this 600x600, it should be maybe 15000x15000 or even more, and for this takes a long time to render
I think I will use FFEASYRENDERER by FFCreator utility to render it automatically during the night and will use 100x100 images as source, or even 50x50 pixels so it will be easier to identify when bomber may break the source image or see some bad result

Thanks SpaceRay for trying to test this, I think it could be useful to know how much resolution is needed to make the bomber work correctly in relation to the output result
