Very lovely baby... Can't help to retouch....hope you don't mind... Who say not sharp, I find it quite ok! ![]() I read somewhere about this, to freeze the motion, you need the shutter of at least 1/f s. So if you're using 50mm, it's about 1/60s. But if theres relative movement, double this speed. From my own experience, baby do move but not that much. And I find it ok to capture hands & legs movement, as other part don't move that much. You need higher speed only when they start to crawl. Me too don't like to flash on baby. On the lights around if you want brighter. If no choice, use bounce flash. |

flash isn't good for their eyes as they are still developing their vision. and esp not when its up close with a 50mm lens
ayukawa, yannh is right, 1 / focal length or more, would negate the subject blur. if you're getting 1/40 at ISO 100, ramp it up to 200 or 400. what camera model are you using? Sony/ KM cams handle ISO the best imho. but if you find pics grainy or shutter speed is still too slow, try the desk lamp method (although watch out for colour temperature, esp if you mix incandescent with flourescent lighting), or wait till the weekend like me btw Samuel's a little less chubby now now that he's teething. saw my wife updating his blog last night, shd have "less fat" pics :lol: keep shooting, they grow up really fast! |

Hi yannh and bro trigger, Thanks for the tips No problem yannh, looks better, did you just crank up the gamma level / brightness? I am now using A350, i had to use ISO 400-1600 to get 1/50 or faster. Thanks again bros! |

Basically just adjusting brightness/contrast, saturation and sharpen a bit. You can also train you iron arm to hold stably below 1/50. A350 should be a very capable camera. |

Hi Nick... I think shutter speed of 1/focal length is to avoid blur due to our hand shake and not to prevent blur due to subject movement. The shutter speed needed to freeze a subject depends on the movement speed of the subject. For a normal walking speed, you should use at least 1/125 to freeze it. For baby, you can use slightly lower shutter speed, probably 1/80 or 1/100. Hope it helps

Adding to bro d4nie's thoughts, I've shot quite a few photos with drifting hair - to catch that, I usually push my shutter speed to around be 1/200 because those things can be quite fast. |

one more thing, as long as the eyes are sharp, don't worry abt the rest of the subject. sometimes a little motion blur adds flavour to the picture. |

lovely baby!!
your photo look good to me . I am using 50 f1.7 lens as well. Another thing is, if after setting high ISO and the image still blur due to handshake/slow shuttle speed, try to turn on more lights or open ur window curtain to allow more light in, this will help as well and make sure u are at the correct light direction..below are the photos i took when my boy was still under 1 month old.. #1 I am soo sleepy.. ![]() #2 what's up?? ![]() |

well from newbie to newbie.. just want to add another solution.. if the baby is asleep.. or not too much movement.. you can go ahead experience with shallow DOF, from f2.8 below. but if the baby is awake or in their active mood.. I'd go with f/4, you'll still get a very sharp image from your 50mm, even without doing any PP. it helps to prevent misfocusing due to the shallow DOF, but still get a sharp image. anyway.., lovely baby.
