after a friend's bridal shower the other day we decided to go out and play around with some of the leftover balloons. I love balloons and taking pictures of them, but somehow several of the pictures came out very grainy. Is it the high ISO? Also, when I upload any of my pictures to my facebook page, they look very grainy though I choose the "high quality" option.

Constructive criticism needed!
Thanks,
Betsy

shot f/22, iso 1600, 1/1250

Increased ISO is associated with more grain.

It's the Hi ISO that makes it grainy..

yeah....
any suggestions on how to get those tack sharp pictures that pros get when they post online?

First you were shooting during bright daylight so you shouldn't need such a high iso, 100 or 200 would be fine. Also lower your f-stop to get a faster shutter speed, f22 is extreme and your image sharpness degrades at such a high f-stop due to diffraction, expecially if you don't have a full frame sensor.

Thank you very much! My grandchildren tell me I should go to a class, but I think I'm too old to learn a lot of new tricks haha

My grandchildren actually posted my question I'm not really good with computers

djmarti Loc: cape cod,

Classes i'm sure will help but the best way to get better is just practice and research. And don't be afraid to ask for advice. You get a lot of good responses and different opinions in this forum. If your not getting good results just remember you will get better and never get discouraged. I've come a long way since I started yet I myself have so much too still learn.

Post processing software could reduce the slight overexposure and may be able to remove some of the noise, but if these are for home use then leave them and enjoy the beautiful memories.

Perhaps the ISO is too high...crank it down a tad...I'll have a sweet tea...please...........

My reply is concerning the fact that you said you were too old to go to a class. I am 67 and I just finished Digital Photography 1 at George Brown College. I am starting Photography 2 on Wednesday. We are never too old for anything... I also completed my 12th grade in Communication and Mathematic (won an award) at GBC in May of this year ! So, GO FOR IT ! it is lots of fun...

What camera / lens were you using? Some handle noise much better than others. You should of been around Iso 100 - 200. I love the 2nd one for colour and composition. Maybe having the girl slightly more to the right for rule of thirds but I like it as is.

Tack sharp images rely on a number of variables. Expensive or shall i say sharp lenses with good optics(not all sharp lenses are pro check lens reviews to establish how sharp they are). Keep away from both extremes regarding aperture. Get focus bang on. Lighting and adjusting sharpness and micro details in raw. Also supporting the camera correctly.

For this photo I used my canon T11 and the canon "L" 35mm 1.4 fixed lens. I think my settings were just dreadful. I am in much need of practice
