How do you apply flat fields

Striker (Tony) · #1 23-10-2005, 07:56 AM

Hi All,

I did my first flat field shots early this morning....now I need to know hot to apply them to the images I have taken..

I had a quick look at Iris and are totaly confused...is their an easy way to apply flats.

What program can I use and is there any easy tutorials.

Hi Tony. Yep Iris can be like that. If you haven't already download Jim Solomons Cookbook http://home.comcast.net/~jimc8ngt/articles/cookbook/ and see how you go. It helps if you can understand the processes he uses, but its not essential. Just follow the steps he outlines.

Tony im surprised you havent got ImagesPlus , as far as i understand it the program does everything in auto mode for you , might be worthwhile downloading the demo and see what you think

Striker (Tony) · #4 23-10-2005, 10:11 AM

Thanks Stuart.....Just downloaded it.....very very easy...just what I needed....too bad the demo has a cross over all images...

May have to buy it...dam

Images Plus- well worth it.
Great features.

Mathematically flat field processing is a "divide". You can invert your flats and then multiply with the image in photoshop to acheive the same result. Although using IP is much easier!

Your not wrong it's easy...I just spent about and hour reading up on Iris on how to do it being completely confused, talk about a long and technical process....and it's only 2 clicks on Images plus.

What about in registax? It has the facilities for it. I have'nt tried it yet though.

Seems like a lot of cash, what other features are useful in Imageplus? I know a lot of guys in the states are using it. Especially the CCD guys.

Striker (Tony) · #13 23-10-2005, 07:45 PM

Yeah I agree Paul.....even with the Free Demo I cant really use it as it puts a black cross over the image.....I wouldn't purchase it just for doing Flats....but it makes it very easy.....nothing comes close for ease of use yet...but I am still looking

Cant help you regarding features....I was just happy to see it do flats.

Heres the page for the features http://www.mlunsold.com/ , with processing being a major factor in imaging nowadays and the money put into the purchase of a DSLR buying a user friendly program like IP is a worthy investment i reckon , if i had the computing power i would have it in a heartbeat

rumples riot · #15 23-10-2005, 08:09 PM

hmmm, looks good Stuart, I can run my D70 straight into it and it helps focus and all sorts of Nikon support. Might have to consider this at some stage.

beren · #16 23-10-2005, 08:23 PM

Only thing Paul the nikon has a infa red shutter release , the cable OPT or hap griffin sells that suits the D70 is expensive but it would save us being slaves to a stopwatch .Even though the program comes with video tutorials i brought a how to handbook for the program and it looks great even from my rookie understanding

Striker (Tony) · #17 23-10-2005, 08:28 PM

Paul,

Have you looked at Chris's DSLR Focus software....I am using it atm.....I just ordered some cables from shoestring so I can control everything including longer exposures over 30 seconds from my PC using Chris's software.

beren · #18 23-10-2005, 08:41 PM

If Paul has Nikon capture you can use Chris program although for shutter release control you still need the infa red cable hap griffin or OPT sell

From OPT Andrew http://www.optcorp.com/ProductList.a...05-258-259-261 theres one aimed for canon DSLRS and the one i have is for the nikon d70 .The main purpose of the book is to get you going and producing results quickly with Images plus , i think the cost was around 30 au , if anyone is interested in loaning it i would be happy to pass it around.

Noticed on the OPT site that Maxim DL has a DSLR software program too http://www.optcorp.com/product.aspx?...3-244-245-7526
