When doing black and white photography which file format should you use if possible?

When doing black and white Photography, it's best to use a lossless file format like TIFF or RAW if possible. These formats retain the maximum amount of detail and dynamic range, allowing for greater flexibility in post-processing. JPEG can be used, but it compresses the image and may lose some quality, which can be detrimental in black and white work where tonal nuances are critical.
