Hi,

I'm fairly new to photography and to date I have been taking landscape photos. I'n some of the photos I have these blotches that appear, their very faint and I can't work out what they are.

Any help would be great.

An image is here with the blotches.
Camera is a Sony Alpha 330a with an 18-55mm lens

Thanks in advance.

Almost certainly "dust bunnies" aka dirt on your camera sensor.

Oh and welcome to TP:)
 
That is dust/dirt/grease on your sensor.
They are visible at F13, will not be so visible at bigger apertures.
Time to get the sensor cleaned :bang:
 
Thanks, I was hoping it would be something this simple. Also updated the link so it works now :)

What's the best way to go about cleaning it. Taking to a shop or by a DIY cleaning kit?

I'm fairly hands on person but my house is all open floor boards so not exactly a dust free environment!

Thanks
 
Try a rocket blower (do a Google if you're not sure what they are) first and foremost, and if that doesn't shift the dirt you can either use sensor swabs if you're feeling adventurous, or get it done professionally. :)
 
Got a rocket blower today and tried it. Cleared up most of it but some are still there.

I have ordered a swob set and I'll see how that goes. Just going to be very careful.
 
I'm new and I also have this problem but it only seems to appear on my kit lens, my only other lens is a f1.8 50mm and it doesn't seem to have this problem. Do you think it could just be dirt on my kit lens or that the aperture of the 50mm just doesn't pick up the dirt from the sensor? Thanks

Unlikely it's dirt on the lens - it would be too far out of focus. It will only show at small apertures - say f/11 upwards. Do you shoot your 1.8 lens at small apertures?
 
The rocket blower didnt work so I brought some swabs and fluid and gave it a wet clean. There are nolonger any dust bunnies.

Thanks for the help
