ND's and CPol's
Simpler to buy a ND filter. Or three. G Since I own a CP already and am getting a bigger one for my 16-45mm, I will already own two of them. So in my case it's not simpler... :) And no, I haven't forgotten about the stepping rings... :) And my understanding was that when a CP is orien...

are ISO settings a nonsense on digital?
This could solve all our low light problems... I'd like to see some actual real info on what it does different. theres a fundamental limitation in terms of the number of photons hitting each pixel, and higher pixel counts and thus smaller pixels make that worse. also using bayer filter arrange...

Black and White photos - critique please
Took these photos a few days ago on my K100D, converted them using the Photoshop channel mixer and adjusted levels afterwards. The sky on both of them is a little burn't out, should've used a grad filter. Let me know your thoughts and how I could improve the framing...I know I cut the top corner o...

Black and White photos - critique please
Hi John, I did do that with the lasso tool, but there is very little if any detail left in the white clouds. Methinks I'll have to go back and hope for a day not quite so bright or use an ND grad filter. I did actually have one with me, but I was too lazy to attach it!!

Well, just to make a slight correction... :P I rave about the "Lee Foundation" set. That's the holder. Superbly engineered and well worth the dosh. I couldn't afford, or justify, the Lee filters. So I went with a set of Cokin Z-Pro ND grads (great price from Speedgraphic). I did get ...

I think you are right that getting a 77mm polariser would be better with some step down rings as the price for a 110/105mm one is crazy. Not entirely :( You see, if you put a filter between the lens and the holder it becomes a right pain to adjust the two! The ideal solution is having the polaris...

My concearn is the sheer cost of circular polorisors from people like Hoya . I use a Pentax DA 18MM - 55MM with a 52 mm filter thread for most stuff. I have been looking for circular polorisers for the lense and i am horrified at the cost ,around £80 from Hoya. I purchased Jessops own brand for m...

Kood CP Filter - any good?
Hi all, I am really getting into landscape photograpy at the mo and have recently purchased a tripod, some Cokin P series ND filters and ND grads. I am also looking to purchase a circular polariser, looking on eBay the Cokin P series ones go for around £40-50, whereas the Kood ones go for less t...

Kood CP Filter - any good?
I've got the Kood P filter. Can't remember where I got it - might have been srbfilm.co.uk Works very well ;) Matt

Cokin A or P
P Because A only covers filter diameters up to around 67mm (I forget the exact size), and as soon as you have invested in a set of A filters, you will buy a lens with a larger filter diameter. It is called Cokin's Law, and it never fails. With a Pentax DSLR, you are very unlikely to buy a len...

Sharpening in Picasa
I use Picasa - mostly to create Albums and gift CDs ;) I haven't looked too much into the sharpening of Picasa, but you might find it's a High Pass Sharpen (which is often nicer than a USM). A quick outline in PSE: * Flatten the image into one layer * Duplicate the layer (you now have two cop...

anybody want to try an experiment...
I've been using this method for years but with either a yogurt carton bottom or the cap from a deodorant. They work surprisingly well and are quite accurate in difficult lighting conditions. I have glued them to a skylight filter so that they fit securely to the lens although you could simply hold t...

too many dark tones....a -1.5 ev would've worked. now for a fix.... get into photoshop (or elements) duplicate the layer...set blend mode to "multiply" repeat as many times as it takes with new layers. now hide the blown highlights with some grain... add a new layer at 50% grey. ...

I have gone for the Cokin filters, though have been looking at a Kood circular polariser, mainly due to cost. From the people I have spoken to, the Cokin filters seem to be better quality, at least in optical terms. Though having never used a Kood filter I can't really comment personally. The C...

One Cokin Z-Pro is usually enough to bring the dynamic range in check - especially with the K10D. I don't have any perceivable tint problems with a single Cokin Z-Pro. (I did hear that the Cokin's were better at rendering blue skies, whereas the Lees are better for moody grey skies. Of course the Le...

This is what cokin.co.uk says about the standard P holder "For shorter focal lengths 20-24 or 28mm as well as for wide angle zooms (24-50mm / 28-85mm / 35-135mm) the Cokin P System is strongly recommended." in the booklet that came with my holder it says this about the wide angle hol...

My guess is that you are not going to see much vignetting using a P series on the 18-55. Don't forget that the digital sensor is significantly smaller than a film frame (which is what Cokin are talking about when they mention focal lengths). And the filter size is a mere 52mm. G
