Abstract
Abstract An array of mirrors is positionable around the lens of a camera for use in combination with flash so that the illumination provided by the array is essentially parallel to and proximate a line from said lens to selected subject matter. This makes it possible to take photographs through an orifice such as the body orifices. The array is collapsible into planar form so that it can be stored in an envelope when not in use.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
171 words
Apparatus for directing light from a flash source associated with a camera proximate to and approximately parallel to a line from the lens of said camera to selected subject matter, said flash source including a light source and a mounting, comprising a first mirror, first holding means for attaching said first mirror to said mounting, spacer means for orienting said first mirror at a selected first angle in relation to said light source, and at least a second mirror positioned adjacent said lens, said first angle being such that light from said light source is directed to said at least second mirror, said at least second mirror being oriented for making a second angle with the light reflected from said first mirror such that a substantial portion of said reflected light is again reflected proximate to and approximately parallel to said line joining said camera lens and said subject matter, said at least second mirror being positioned for allowing ready access to said camera lens and attachment of a close-up lens.
Claim 2
Dependent Claim
171 words
Apparatus for directing light from a flash source associated with a camera proximate to and approximately parallel to a line from the lens of said camera to selected subject matter, said flash source including a light source and a mounting, comprising a first mirror, first holding means for attaching said first mirror to said mounting, spacer means for orienting said first mirror at a selected first angle in relation to said light source, and at least a second mirror positioned adjacent said lens, said first angle being such that light from said light source is directed to said at least second mirror, said at least second mirror being oriented for making a second angle with the light reflected from said first mirror such that a substantial portion of said reflected light is again reflected proximate to and approximately parallel to said line joining said camera lens and said subject matter, said at least second mirror being positioned for allowing ready access to said camera lens and attachment of a close-up lens.
Claim 3
Dependent Claim
24 words
Apparatus as claimed in claim 1, wherein said holding means for attaching said first mirror is pressure-sensitive tape in combination with said spacer means.
Claim 4
Dependent Claim
17 words
Apparatus as claimed in claim 1, wherein said at least second mirror is positioned below said lens.
Claim 5
Dependent Claim
17 words
Apparatus as claimed in claim 1, wherein said at least second mirror is positioned above said lens.
Claim 6
Dependent Claim
42 words
Apparatus as claimed in claim 4, wherein said at least second mirror is held releasably in place by pressure-sensitive tape and second spacer means for orienting said second mirror to direct light received from said first mirror to said selected subject matter.
Claim 7
Dependent Claim
62 words
Apparatus as claimed in claim 1, wherein said second mirror is placed to one side of said lens and a third mirror is placed to the other side of said lens and said second and third mirrors are disposed to reflect light from said first mirror proximate to and approximately parallel to said line joining said camera lens and said subject matter.
Claim 8
Dependent Claim
49 words
Apparatus as claimed in claim 1, wherein second mirror and third and fourth mirrors are positioned respectively to either side and below said lens and disposed to reflect light from said first mirror proximate to and approximately parallel to said line joining said camera lens and said subject matter.
Claim 9
Dependent Claim
21 words
Apparatus as claimed in claim 7, wherein said second, third and fourth mirrors are joined to each other by pressure-sensitive tape.
Claim 10
Dependent Claim
68 words
Apparatus as claimed in claim 7, further comprising a fifth mirror mounted above said lens and held to said camera and flash source by pressure-sensitive tape and spacer means for establishing the angle at which said fifth mirror is held, said fifth mirror being disposed to reflect light from said first mirror proximate to and approximately parallel to said line joining said camera lens and said subject matter.
Claim 11
Dependent Claim
24 words
Apparatus as claimed in claim 1, further comprising means for shading said lens from the light reflected by said first mirror toward said lens.
Claim 12
Dependent Claim
32 words
Apparatus as claimed in claim 1, wherein said flash source is a strobe unit and said second mirror is mounted on one of said strobe unit and the body of said camera.
Claim 13
Dependent Claim
25 words
Apparatus as claimed in claim 7, wherein said camera has a bed forward of said camera lens for supporting said second, third and fourth mirrors.
Claim 14
Dependent Claim
15 words
Apparatus as claimed in claim 1, wherein said camera lens has thereon a close-up lens.
Claim 15
Dependent Claim
31 words
Apparatus as claimed in claim 1, wherein said subject matter is on the far side of an orifice and said light must pass through said orifice to illuminate said subject matter.
Claim 16
Dependent Claim
18 words
Apparatus as claimed in claim 1, wherein said line is approximately coincident with the axis of said lens.
Claim 17
Dependent Claim
39 words
Apparatus as claimed in claim 7, wherein said second, third and fourth mirrors are mounted on pressure-sensitive tape in spaced relation to facilitate forming dihedral angles between said second and third mirrors and between said third and fourth mirrors.
Claim 18
Dependent Claim
46 words
Apparatus as claimed in claim 16, wherein the edges of adjacent mirrors are nonparallel by an amount sufficient to compensate for the combined effects of dihedral angles between said mirrors and the angles between said mirrors and the line from said lens to said subject matter.
Claim 19
Dependent Claim
47 words
Apparatus as claimed in claim 1, wherein said second mirror is positioned above said lens and a third mirror is positioned below said lens for reflecting light from said first mirror proximate to and approximately parallel to said line joining said camera lens and said subject matter.
Claim 20
Independent Claim
191 words
A method of illuminating subject matter to be photographed through an orifice, comprising the steps of disposing a first mirror on a flash source associated with a camera, placing at least one mirror proximate to the camera lens, orienting said first mirror to direct light from said flash source to said at least one mirror, and orienting said at least one mirror to reflect light from said first mirror proximate to and approximately parallel to the line joining said camera lens to said subject matter, said first mirror being positioned relative to said flash source with pressure-sensitive tape and oriented by first spacer means for reflecting light from said flash source to said at least one mirror, and said at least one mirror comprises three mirrors positioned below and to either side of said lens, said three mirrors are joined together by pressure-sensitive tape in an array which can be laid out flat, and wherein a mirror is positioned above said lens, said supra-lens mirror is releasably joined to said camera body by pressure-sensitive tape and oriented by second spacer means for reflecting light from said flash source along said line.
Claim 21
Independent Claim
