| | Dr. Bill's Notes on 24 Bit .BMP Files |
 | | The formats smaller than 24 bits include a palette as part of the.BMP file, but since 24 bit images do not require a palette the file is correspondingly simpler (and the appropriate entries in the header record are set to zero). | | | 24 bit.BMP *) (* files require that each raster be a multiple of 32 bits *) (* (4 bytes) in length, so depending on the number of pixels*) (* in each raster line, we may have to write out between 0 *) (* and 3 zero bytes to pad the line properly. | | | Some fields are not used at all, some are not used by the 24 bit format, and some don't seem to be used correctly by a few of the programs I've tested. |

| | RGB color model - Wikipedia, the free encyclopedia |
| | Typical display hardware used for computer monitors in 2003 uses a total of 24 bits of information for each pixel (commonly known as bits per pixel or bpp). | | | The so-called 32 bpp mode is almost always identical in precision to the 24 bpp mode, there are still only eight bits per component, the eight extra bits are simply not used at all (except possibly as an alpha channel). | | | With only 8 bit per component, rounding errors tend to accumulate with each filtering algorithm that is employed, distorting the end result. |

| | Color and Bit Depth |
| | A 24 bit color image that is then saved to 8 bit color will be 1/3 the size, because there is 1/3 the amount of color information in the image. | | | The terms 30 bit and 36 bit refer to formats that have an increased number of bits per RGB color channel available (i.e.: 10/12 bit per channel for 30 bit), that gets interpolated back down to 24 bit color for processing. | | | The term bit depth is used when referring to raster images produced by programs such as PhotoShop and PhotoPaint. |

| | IDL Colors on a 24-Bit Display |
| | The red index is taken to be the lowest 8 bits, the green index the middle 8 bits, and the blue index is the highest 8 bits of the 24-bit value. | | | That is, the value 100 written as a 24-bit binary number is 00000000 0000000 01100100. | | | What this means is that IDL in this mode assumes that the value is a 24-bit value, and "decomposes" that value into three 8-bit values, which it uses to independently index the red, green, and blue locations in the color table. |

| | The format of the input or output (16 or 24 bit) has no influence on the precision with which the program does its internal signal processing | | | If you'll buy one of this cards later you'll be able to upgrade to the 24 bit version for the exact price difference between the standard and 24 bit version. | | | 24 bit recording and playback is currently available only on very good quality soundcards, such as the Creative Audigy 2, MIDIMan Delta cards, Echo Gina, Darla and Layla. |

| | David Blatner and Bruce Fraser in their book 'Real World Adobe Photoshop' do even suggest that you convert your 24-bit files to 48-bit before you start anything like sharpenning etc. As this doesn't add any information to the image, it gives data points more places to land after any step of editing. | | | The time for noise reduction and sharpening was the same for both the 48 bit and 24 bit versions of the same photos. | | | I found it took between 7 and 9 percent longer in 48 bit than in 24 bit. |

| | CodeGuru: Full-Featured 24-bit Color Toolbar |
| | CBitmap::LoadBitmap() converts the bitmap to the screen's bit depth, so the Win32 function ::LoadImage() is used instead to create a 24 bit DIBSECTION, which is then attached to a CBitmap so it can be passed to CImageList::Add(). | | | Since the Visual Studio graphics editor can't handle 24 bit images, you must edit the images in another program that can, such as GIMP or Adobe Photoshop. | | | Making the image lists 24 bits deep requires creating the CImageLists with no images, then loading the images as CBitmaps, and finally copying the CBitmaps into the CImageLists. |

| | Is 24 Bit Recording Really Better? |
| | Again, one file was dithered from 24 bits to 16, another was truncated, and three others were reduced to (approximately) 13 bits, 11 bits, and 9 bits respectively. | | | Even though a 24-bit recording will be reduced to 16 bits for distribution on CDs, conventional wisdom says that recording at 24 bits is always better. | | | One copy was reduced to 16 bits using SAWPro's "Dither Type 2" algorithm, and the other copy was simply truncated to 16 bits, also in SAW. |

| | 24 bit address in 16 bit processor |
| | Is there an elegant way to access structures in that 24 bit address space or does it have to be bent folded and mutilated to access? | | | Normally you just add on some high order address bits in custom hardware, perhaps an I/O port, and thus have full 64k segments (addressed by the DPTR) plus another byte that holds the "segment register" (if you want to think of it that way). | | | Currently all addresses are specified with an 8 bit 'page' and a 16 bit 'address' and processed as such. |

| | 16 vs. 24 bit Audio Recording Demystified |
| | Because I do all my recording on computers with sequencers, 24 bit files seem easier to work with. | | | My advice is to record at 24 bits/44.1 at minimum and go up to a sample rate of 88.2 or 96 if you think your material warrants it (and you have the disk space). | | | Today, your audio interface is probably 24 bit and allows you to select sample rate of your choice, 44.1, 48, 88.2, 96 and even 192khz. |
