Ever seen the common aspects of published food shots on magazines and online? That clean fresh pearly white look on the photo is almost always a must on a food photography.

Just look at the difference of the spaghetti with salmon below. Although I forgot to take the original in raw format, the jpeg on the left had a slight gray overcast. To get rid of the grayish tones, I tweaked the exposure levels on photoshop and used the white and black ink droppers to indicate the whitest and blackest portion of the spaghetti. Take note how the histogram changes. What a difference the exposure makes!

Note: Shooting is best done in raw format so you won't loose quality of the pixels while editing photos.
