Infinity Curve versus white background

[Maro]

• Is it possible to create an infinity curve effect with affinity photo. Applying a white background to full length portrait is straight forward but doesn’t seem produce an infinity curve? The impression of depth seems to be missing with a plain white background.
  • With a background that is complicated the depth of field tool could be used,
  • With a patterned background (e.g. polka dots) a combination of the depth of field and perspective tools could be applied
• My question is how could it be done with a single colour? White, grey or red for example.

Any help would be appreciated or if someone could point me in the right direction.

Welcome to the forum @Maro I am assuming you are referring to something like this: https://www.shootfactory.co.uk/what-is-an-infinity-curve-or-cove-in-photography/ used in Photography.

The issue here is we are talking about 3D space but Affinity Photo can only handle 2D, it has no 3D capabilities.

Reading the description in @firstdefence's link makes me wonder: How does the resulting image with using an infinity curve differ from simply cutting out an object and placing it on a white background? Quote: "The end result is a finished image where the subject appears to have been placed on plain white paper or a blank canvas." I'm afraid I don't get how this would ever create an impression of depth.

It amazes me how we can discern fake from reality, the subtlety of heavily diffused light on a white background can be enough to give a sense of depth, the omission of light by the subject/object however faint that may be is enough for us to know it looks right, so, the possibility is that the very faint shadowing will give enough of an illusion to give a representation of reality. Instead of trying to get a flat white background try a very faint dappled background or work out where faint shadows should be. There has to be some tonal variation across a surface unless the lights white-out the surface but again that isn’t going to be a real-world experience because there will be some reference that has a tonal difference.

A man with a shadow over a blurred wall background can give an impression of depth.

If you simply remove the wall do you still have an impression of depth?

PS Not sure where an Infinity Curve fits into all of this, maybe the OP needs to show an example of what they are trying to achieve

@firstdefence: The slight shadow approach was one way I was considering, I will give it a try.

The difference is a problem for full length portraits, head shots not.

Thanks for your insight.
