Hi Emmanuel,

1. Two small dots to the right and above that building in the back ground.
2. Dust spots all over, equalize it and you will see them, there are at least 3, and also a couple of white dots above the letters on the 737.
The rest have dust spots everywhere again.

Hope that helps.
Ivan

If you don't see them on the normal picture, use the equalise function and you'll definitely see them.

You can clone them out, which I prefer, or use the spot healing brush tool.

A tip for others with this problem, and don't we all at times?
I find that it is very rare for a dust spot to be bad enough to show up anywhere but the sky.
If you select the sky and just equalise that, they hit you.
Might be a tip for others to try

Emmanuel,
have a look at Ferguls workflow, a PDF on the upload page. That will give you some tips.
Your sensor needs a good clean before your next trip out and there is plenty of advice to be had on the Forum about methods of doing that.

Those are damn good photos. These guys are just hard-core. Makes me think there is no point in even trying unless you have all the money and/or time in the world.

A really helpful comment from SATX.
I have always found time to clean my sensor, a few seconds and the cost is negligible against that of the camera/lens.
It is time consuming to NOT clean the sensor!
Emmanuel, they are good shots, but not YET good enough.

I'm not the brightest bloke around but your point is......??? Don't know what all the money has to do with dust spots!!?? If it's the time to take out to clean your sensor, then it's negliable, I do mine in less than 5 mins and the cost is low too. I got my pec pads and my eclipse fluid which will last me for the next year or so. If you going to spend a lot of money on equipment then you have to do the maintenance too.
Hard core???   

Emmanuel   

You can get more info on cleaning your sensor here, it's fairly simple to do.
http://www.pbase.com/copperhill/ccd_cleaning

Below are some links to Eric's and my workflow, both of which will show you how to clone out your spots
http://www.rockymountainavphotos.com/Kyle/Workflows/Workflows.htm

Edit: As with any workflow,Checking for dust spots should always be part of it, the equalize funtion is not only good for spots but I believe it's also good for checking against bad borders.

Take care and good luck

Fergul,

Really excellent link that on sensor cleaning. Do you (or anyone else out there) know if there is a supplier of PecPads and Eclipse Fluid in the UK ? If so do they do mail order ?

If there is no UK supplier where do you get your supplies from - the supplier in Switzerland ?

Many thanks in advance for any further info.

Warehouse express are good for cleaning stuff, Click on Gigital and then on the side menue click on cleaning and you will see all the gear you need. All you need is a sensor swab, pec pads and fluid. I bought mine from the US, Copperhill but they can't send the fluid so I got that from Warehouse.

Good luck.

It was very difficult for me to discover the problems with this photo set. I looked and looked and yet I just couldn't see most of the defects. Sure, when the picture was modified specifically to show the aberrations then I could see it, but if it's that hard to notice the problems in their native format then I'm a little confused about what the big fuss is.

I assumed that maybe if I spent more on my monitor and video card I might have been able to pick-up on the problems or maybe I would have been able to see more of the defects if I had a lot more time to play around with the photos in PS. Thus I made the comment about needing to spend more money and time than I would consider reasonable to find and correct these sorts of issues.

I'm sure my comments must seem pointless to an expert, but for those of us who don't know much about photography, getting more than a few photos accepted at today's A.net is a rather daunting challenge. That's all I was trying to say.

SATX - The 2 dust spots are circled in the example I posted are clearly visible on my monitor, without taking the picture into Photoshop.

I'm no expert, trust me!
I don't have expensive equipment, just your standard Dell 4600 with a 19" flat CRT. I agree that the spots in question are difficult to see to the naked/untrained eye but you must remeber that the screeners are doing this every day and when you do that you will become acustomed to spotting the flaws, like dust spots etc.
That is why you should always include dust spot checking in your workflow, it doesn't take that long to do it.

Your second post is a lot more understanding, thanks for making it clear, to me anyway.

Take care
