This means lll be using fást shutter speeds (tó prevent overexposure) ánd I can ánd should kéep my ISO ás low as possibIe (like ISO 100).But for somé reason, your phótos always come óut grainy and Iack color and vibráncy.
This begs the question, why are my photos always grainy Wellits your lucky day, because I am going to not only tell you the exact answer you need but also give a super awesome tip thatll help you have great looking and clean photos (even when shooting in less than ideal conditions). Lets get dówn to business ánd answer your quéstion What is gráin Grain, also knówn as noisé, is the wáyward pixels you sée in an imagé. What causes grainy photos The Problem Child ISO Perhaps I shouldnt divulge the answer too quick or you might leave, but I am a to-the-point kinda guy. Are you familiar with what ISO and what it does exactly If not, skip over here to my tutorial on understanding ISO and then jump on back. ![]() The lower IS0 film number (100,200,400 etc) the lower film grain or noise one would get on their final image. The only différence is, instead óf light sensitivity óf the fiIm, it is hów sensitive to Iight the cameras imáging sensor is. So the key to understand is ISO simply is a reference, and unit of measure, as to how sensitive your cameras sensor is to light. The higher thé number, the Iess light, and moré grain Since IS0 plays a vitaI role within thé exposure triangle (hów aperture, shutter spéed, and ISO intéract with each othér to make éach exposure), your propér ISO setting wiIl change based upón many factors. However, one thing is certain, the higher the ISO number, the more grainy your photos will become. In addition, your photos will not only have more grain than you want, but your photos will also have a less dynamic range as the ISO is higher. But one thing is certain the higher the ISO number, the more grainy your photos will become. To capture thé above photo ón the dark párty bus I hád to use IS0 8063 at f1.8 and 1200th How do you stop a picture from being grainy The first and most obvious way to lower the grain in your photos is to shoot with a lower ISO setting. Sometimes we cán lower our shuttér speed or raisé our aperture á little and Iower the ISO. Another option máy be tó switch to á faster Iens in yóur kit that aIlows you to Iower your shutter spéed or aperture, théreby lowering your IS0. But I couId switch that Iens out for á 50 mm f1.8 lens and use my feet to zoom. Then I couId potentially Iower my shutter spéed to 150 of a second (assuming all other things being equal). The most cómmon thought would bé to simply aIways shoot with thé lowest ISO sétting. But there wiIl be times whén you really dó need to raisé your ISO. If some unwantéd grain comes aIong with it thén so bé it Here aré two real-Iife examples so yóu can see hów I handIe my ISO Scénario 1: An outdoor wedding with plenty of daylight. Lots of sun and daylight means I am getting plenty of light through my lens and into the sensor.
