Skylight / UV Filter lens protection

This has been covered extensively on other threads... will dig out the thread when I can. ...most recently on this one - - which started out as a 2x convertor question, but just past halfway down suddenly veers into UV filters for protection. Dan

Skylight / UV Filter lens protection

Thanks everyone for the replies. It looks now that my decision is filter on or off. More headaches!

Skylight / UV Filter lens protection

Hi, The only company that I know that used to make clear glass protection filters was Contax. They made Contax 'P' filters in mainly 55mm thread, but also very rare ones in 49mm. They can be found occasionally on the used market. The majority of amateurs tend to use filters to protect their le...

Skylight / UV Filter lens protection

Many lenses are now provided with dedicated hoods, so there is no excuse for not using them! :wink: Previously I always bought the dedicated hood, which could add £30 or more to the cost of every lens. :( So, life has improved! :D

Expodisc / Expocap

Golfdiesel, I have the 67mm Expodisc. It's been great... but ;) Remember the Expodisc was created for getting incident light readings, and the white balance was a side-effect/logical-consequence of the design. As an incident light meter it works a treat. As a white balance product it works a d...

Expodisc / Expocap

Not sure how SP does its skin tone balance, but I've found that clicking on a few areas of skin will eventually get a good WB. They probably do it with some kind of statistical analysis - even manual skin tone corrections can be almost worked out by number (see Katrin Eismann's book "Photoshop...

Old England in the Fall..

Well, I don't have access to Old England in the fall, but here is a link (sorry, could be a bit problematic again, don't know why) showing fall 2004 in the New Forest, Hampshire. I added a bit of glow to it with PS... Pentax *istD, PENTAX-FA J 18-35mmF4-5.6AL, 1/90s, A16, ISO200, gradient filter...

Extension tubes!

Insight from a newbie... I have a Pentax 1 bellows as well as a set of Haminex "auto" tubes. I've tried all the various combinations I can think of with 28, 50 and 135mm lenses (don't have a Pentax 200mm unfortunately), and I seem to wind up with the 135mm most often. The beauty of the...

Gradual Neutral Density filters

Mr ist, I think your confusing graduated filters and ND graduated filters, graduated filters come in allsorts of combinations from various graduated colours to graduated "effects" Nuetral Density or ND filters are simply used to reduce the light reaching the film/ccd and do not colour ...

Gradual Neutral Density filters

Thanks v. much for pointing that out - I didnt realise there was a difference, although I think I need the difference explained as I'd have thought a filter with grey fading to clear would give the same effect as an ND grad. :o

Gradual Neutral Density filters

The important word is 'Neutral', as opposed to 'grey'. A neutral filter should not introduce any colour cast, whereas a grey one is not necessarily neutral in it's colour, so skies may take on a green or magenta tint, for instance. Basically, if a manufacturer doesn't want to have the trouble of...

Gradual Neutral Density filters

Hi IS, As far as I'm aware, the look of the sky would be purely dependent on the strength of the filter - a 3 stop ND would darken a sky more than a 1 stop ND, and could thus make it look stormier if this darkening was more than was needed to balance the exposure. The Cokin website intrigued ...

Gradual Neutral Density filters

Gents - a word of advice here... if you are looking into using grads for the sole purpose of balancing the sky/foreground exposure on your landscape images - there really is very little choice... I kicked off years ago using Cokin A series filters, then onto the bigger P series as I wanted more wide...

ND Grad filters

The advantage of the Cokin type system is that you only need to buy one polariser for all your lenses, which can save you a heap of money. If you've got 2 or 3 (or 5 like me) lenses of different filter sizes, especially if they're larger sizes (67 or 72mm for instance), you'd be much better off. ...

ND Grad filters

I was thinking about getting hold of some ND grads as well, and finally did a couple of days ago. I have a cokin 'A' gradual grey, which does affect the colour in the photo, but makes for some interesting effects. I've never used one, but apparently Lee filters' ND grads are truly neutral density an...

ND Grad filters

To avoid scratching your filters, why not try a cd case like the ones you can pick up in music stores? If you're using Cokin A or P filters, just a single height one will be sufficient or grab a double height (2 x CD's to one page) to store Lee or Cokin ZPro grads. I use this method, storing just on...

ND Grad filters

I had a play with my new nd filter :) I always wondered how to capture the silky effect of moving water. I wish i'd had a tripod, but I'd say it isn't bad for 1/2 second handheld. What do people think?

ND Grad filters

Now I can see it :) You could do with an ND Graduated filter too - that would balance the sky exposure with the foreground. More playing.... Matt
