comment How can I amplify the light from a tiny white LED through a keyhole?
Several questions above have not been answered and answers are needed to help you: How close can the source be to the door? Why? Is the target offset so there is no parallel path to it etc. What you ask for MAY be trivially easy or not, but we cannot tell. You can focus light from an LED to a point at a distance from say mms to m's from the LED end. A suitably small diameter LED and lens could send most of its light through a keyhole in a diverging or converging cone. We need to know why this would not be adequate. A picture showing light PATH, camera location and object location is needed.

comment How can I amplify the light from a tiny white LED through a keyhole?
If you could explain what you are actually doing and perhaps show us a better lit image of the setup it would help. You do not say WHY you want to do what you ask or why an alternative is not acceptable. To say that the double keyhole is an important part of things does not tell us much - just sets a riddle. What you tell us is of course your choice, but you could far better explain what you want. Why 1000 lumen,. How close can the source be to the door? Why?> Is the target offset so there ios no parallel path to it etc. What you ask for MAY be trivially easy or not, but we cannot tell.

@Arkanon - I don't rate out of N but none have a perfect score.| Rating scheme(s) that count most are: (1) Photos I've taken that I like a lot. (2) Photos from 1. that other people like. (3) MAYBE some photos from 2. that are not in 1. | When the bride / person turned 21 / similar keeps saying "The photos are fantastic" I feel I may be winning. (Not TOO common. Twice lately. Happenstace) |My perhaps most 'popular' photo, that I like but am surprised at the reaction to, is of Kangaroos. My (arguably) all time favourite photo would be passed by by most and I'm not 100% sure why I rate it so.

... files. Works. Lose about nothing (as far as I know :-) ) so far in 15 years and can find almost any photo or event I can remember a small amount about. (Meaningful naming of folders plus a few seed long named photos helps). Works for me. Better exists.

@SailorCire That was meant to obscure other stuff - not to provide information :-). 33TB + a small SSD. Photos the main size driver. "With great difficulty". Currently rationalising usage with smaller older drives being slowly combined onto larger ones. Mix of 1 1.5 2 3 4 TB. NO formal mirroring. At least two copies of historically stable folders (usually more) on separate drives. One or more mirrors of annual or semi annual folders of by-event and by-date folders. | XXCOPY is your great friend! | Run an occasional index run over all photo folders to create about 500 GB searchable index ...

@RomeoNinov This is certainly not a duplicate of the question referenced. The other asks how to view EXIF information. This asks how to do it persistently while stepping through photos. Some offerings do that very poorly or not at all. There are no doubt a number of good solutions and hearing of a few more would be useful. I went into the detail I did because it's only "trivially obious obvious in retrospect" and the options of customisable format or std screen on second monitor are both useful. I like the custom format as I can maximise readability know exactly where to look when scanning.

comment How do I get a two person portrait with the background blurred using a DSLR and 50mm f/1.8 lens?
There MUST be many existing answers on SE already and there are countless 1000's on the wbe. You can find calulators and formulae that give you depth of focus in given cases, but.| Set lens to f/1.8 for best result. Aperture priority or Manual mode allow this. (Auto modes will if you play with overall settings). Make distance tobackground : distance to subject ratio as great as you can (or accept what is available). Focus on subject. Go. | For abs best result focus short of subject as much as possible while having subject acceptably sharp. Usually DOF is too shallow to have any choice.
