Using long exposures to make videos? A variable density filter sheet that is slid across the lens or a series of neutral filters that can be added or removed as desired - or a binary weighted set, would probably be useful. Does not address all issues. |

Without modification, is the built-in pop-up flash EVER appropriate? No great photographic merit is claimed in any given case. Some I like greatly - but for me the memories probably influence the perspective as much as the content does. |

Without modification, is the built-in pop-up flash EVER appropriate? @mattdm - see additions to my answer and webpage of "samples". Polite comment welcome :-). As noted on the page: In each case the camera’s popup flash is believed to have been used BUT in some cases an external flash may have been used. Many are non ideal, and I had to resist a strong urge to "improve" some aspects. These are in many cases either trip records or documentary. Some of the fill-flash versions are good examples of how the on-camera flash can help the result. Some others are less than perfect but make the photo better for its intended purpose than it otherwise would have been. |

Without modification, is the built-in pop-up flash EVER appropriate? I'm gently gob-smacked at the lack of willingness and/or ability of people to use this tool to best advantage. I have few illusions about how many friends that observation will make me :-) |

What is the lowest level of luminous flux a camera can detect? @jrista - if you have the time and patience to wade through this DPReview user discussion you'll have that question answered and learn quite a lot that is related besides. There are several quite capable and high powered people there banging heads together rather solidly but they largely seem to come to a good degree of agreement overall. Max DR of a sensor is one of their easy topics. It is generally agreed that gains due partially due to dithering allow up to +1.8dB more dynamic range than ADC bits. |

How do I keep both the background and foreground in the image in focus at the same time? Small aperture - say around f/22. Smaller may work BUT diffraction plays an increasing part at smaller apertures. Point at which diffraction starts to offset effects of depth of increasing depth of field vary with lens and scene. Akram suggests standard focusing rule BUT try moving the centre point to and fro somewhat to suit your image. You can "cheat" with 1. a multiple image shot and careful post melding. 2. A panorama using a good stitching program where you use overlapping slices and move focus point somewhat per slice. |
