I wonder what does happen if you open a boobytrapped .tif file and how would one recognise one?

Developing a black and white film isn't too complicated. All you need is a developing tank, thermometer, some developer, fixer and stop bath (optional.) Plenty of rinsing water and maybe somewhere dark to load the film if it isn't a daylight loading tank such as Agfa's Rondinax.
For colour you would need to purchase a C41 developing kit for most current negative films (C-22 for much older ones.) These aren't particularly cheap and it might still prove easiest in the long run to get the film processed in a lab.
I'm pretty sure most current photo software should be able to balance out the orange film mask on colour negative films (eg even the software that came with the scanner?) While I'm sure you would get OK scans from your normal flatbed, a dedicated film scanner would be better.

When used close up, the Pentax 18-250 drops to nearer 200mm at the long end.

So I've misunderstood that, then, and thought I was right because of the piece in the front of the manual that compares angle of view between film SLR and Kx. You learn something new every day.
I'm sure that's a fair comparison still as the lenses would be affected on both film and digital just the same. It's really just a guide but would hold true for prime lenses.So I've misunderstood that, then, and thought I was right because of the piece in the front of the manual that compares angle of view between film SLR and Kx.

Ok I have taken 3 pictures of a fridge butterfly and cropped the butterfly in light room so that only it was in the image.
18-135 @135 was 1383 x 807 pixels
55-200@ 137.5 was 1993 x 1158 pixels
135 was 2171 x 1276 pixels
Now allowing for not too accurate cropping I would assume they should all be roughly the same.
How can you be certain that the zooms were both set to 135mm? Those markings on the lenses are only approximate.Ok I have taken 3 pictures of a fridge butterfly and cropped the butterfly in light room so that only it was in the image.

To see if they were at 135mm, playback each of the images in the camera and press the info button until you see the more detailed info screen; it's shown there, or get it from the EXIF data in Lightroom.

No-one really knowns when PR will announce a K5 replacement so who knows if it will be a must have upgrade or not - it's also going to be much more expensive than a K5 body..
On the other hand, a K-01 body is cheaper still... (though the rubber door doesn't impress me much)
So I guess the question is to those who have gone from K7 to K5, are you totally satisfied that it was the right choice and have you kept the K7 as a backup or was it easy to sell?
Photokina in Cologne from 18-23 September is a possibility for big announcements, maybe?No-one really knowns when PR will announce a K5 replacement so who knows if it will be a must have upgrade or not - it's also going to be much more expensive than a K5 body..

I've still got a Samsung GX20 and K-m as backups! It is tempting to get another K-5, no wish to get a K-01.

Hi all just wondering if anyone has upgraded and have a copy of cs3 or cs4 they would be happy to transfer for an acceptable sum of money. I bought a copy of cs4 from amazon but on install it said the serial was invalid ie fake so am a bit wary of repeating that exercise.
I understand that there is a form that has to be filled out by the previous owner when transferring the licence so if anyone has an old copy I am interested
Contact the seller and ask them to de-register that copy's serial number as you are its new owner and you wish to register it now, or ask for your money back.Hi all just wondering if anyone has upgraded and have a copy of cs3 or cs4 they would be happy to transfer for an acceptable sum of money.

Can't believe Amazon themselves would sell pirated software so presume this was from a marketplace seller.
Anyone upgrading would need to keep their old version as it is the basis from which the upgrade was made.
