Histograms still elude me, as what I often perceive as a good histogram doesn't always result in good exposures on the computer

Sorry, the DX7440 will not display histograms.

The histogram is a tool that is useful to the photographer that shows a graph that represents how much color or bright and dark areas are in a photo. If you're looking at a photo that has a larger portion of the histogram graph on the left, it means there's a lot of dark / black tones - and that details in those areas are likely lost. The same holds true if the graph was heavy to the right edge - but it would mean there is a lot of bright or whites. Subtle details in these areas would also be lost. You can use the graph to adjust your exposure so that these details are visible. A wedding dress that lacks the fine lace details because the whites were "blown" (over-exposed) lacks interest when compared to a photo that preserves the details. Here's a link to a site with some great info in general - and about histograms specifically. Check it out.

Tinker with exposure settings to move the large areas of the graph away from the edges - this will show the details. You can switch the histogram off and on as you see fit.

Hi,

Microsoft Excel is a commercial spreadsheet application . It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications.
Microsoft Excel has the basic features of all spreadsheets, using a grid of cells arranged in numbered rows and letter-named columns to organize data manipulations like arithmetic operations. It has a battery of supplied functions to answer statistical, engineering and financial needs. In addition, it can display data as line graphs, histograms and charts, and with a very limited three-dimensional graphical display.

You need to turn the mode dial to Manual (M). You won't be able to use the camera's built-in exposure meter at all with this lens. You can take an exposure reading with another lens to use as a starting point, then review the pictures and histograms to fine-tune the exposure.

Correct, you don't want the flash.

Some cameras have a fireworks mode, Unfortunately, the SD400 doesn't. As far as I can tell, the SD400 doesn't even have a landscape mode, which would have been my second choice.

I'd start by turning off the flash in Auto mode. Unfortunately, the camera is going to try to make the night sky a medium gray. You'll have to reduce the exposure using the exposure compensation feature. Review your pictures and examine the histograms to fine-tune the exposure.

My other approach would be to use the manual mode, reviewing the images and histograms.

Either way, take lots of pictures. Feel free to experiment with various exposures. Remember, there is no "magic bullet." Your sky isn't going to look the same as mine, so my settings won't necessarily do you any good.

Hi Joseph
I posted a response at your other post.

Did you download 3rd party APP's or stuff not from the TI site? My programs work, by running some of them might bring the calculator back is all I can think of. [email protected]

i don't think it is an issue with the printer, try increasing the brittleness using some photo processing software and then try.

The flashing is the HIGH KEY area or highlights .Read camera manual on exposure for highlights also read the section on histograms to help you understand the relationship of exposure and contrast.

A histogram is a graphic representation of the distribution of brightness values in an image. The C-5500 has two histograms. One displays a real-time graph on the LCD screen as you compose your images and during the Quick View of images after they are shot. The DIRECT histogram displays potentially over and under-exposed areas in the image with a grid of squares—red for over-exposure and blue for under-exposure. You can set the histogram to OFF to prevent the histogram from appearing.
