Some time ago I used to shot with a B+W ND 3.0-1,000X SC round filter with spectacular results until it fall off to the ground... due to this I started to study the best alternative in the 100x100 size, because it allow me to use ND grads without any vignetting.
I have been searching for a square (100x100mm) ND3.0 filter and I found this list:
There are miles of reviews about the Lee Big Stopper and others filters, like the Hitech ND3.0, but now there are a new competitor in the filters sector, Haida, a Chinese company that are making high quality filters using Scott glasses (the same glass used by B+W) with a good price.
In will not to do an extensive or professional review because I'm not an expert in filters.
I shot in a cloudy/rainy day with some sun rays once in a while, I know it was not the best day to test the filters.
The photos have been posted without any retouch, directly from the Adobe Camera Raw.
In the photos below you can see that the Lee (5950K) is cooler and the Hiada (5000K) is warmer, but not so warmer like the B+W round filter (see here) for my the photo have the perfect temperature with true colors.
In the next ones you can see a 100% crop of the images. I don't know if I'm wrong, but for my the Haida have a better definition.
And to finish an extreme b+w (yes, I love the exploded sky)...
I am very glad to announce this good news.
One of the most professional and good standing photography shop in Barcelona will support me in this project.
Soon could be possible to buy 3DPideas products in this shop and also play with them in theirs photographic workshops.
In this shop you will find all the hi-tech photographic technology that you can imagine (the Leica section is incredible), if anyone are visiting Barcelona I recommend you to visit this shop.
Lee have his own Ultra Wide adapters to use with ultra angular lenses that allow you take photos without any vignetting, but is it possible to improve this adapters?, are you using the Lee holder and want to use screwed filters?.
At this moment I'm testing the adapter C83L (that has been designed to work with the Lee holder) with a Lee compatible plastic holder.
The advantages of using this adapters in my opinion are:
La marca Lee dispone de su propio adaptador Ultra Angular para lentes ultra-angulares el cual permite sacar fotos sin viñeteos (en casi todas las configuraciones), ¿pero es posible mejorar estos adaptadores?, ¿estas usando el portafiltros de Lee y echas de menos poder usar filtros roscados?.
En estos momentos estoy testeando el nuevo adaptador C83L (el cual fue diseñado para funcionar con el portafiltros de Lee) con un portafiltros compatible.
Las ventajas que tienen los adaptadores diseñados por 3DPideas son:
I want to start my first article in this Blog to show how it's possible to mount Cokin P filters in a Cokin Z-Pro holder using the 3D printing technology.
There are people that jump from the P (84x84mm) filters to the Z (100x100mm) filters but they want to take advantage of his old filters and they can't.
I was searching through the web but I only found awful plastic adapters to mount A filters in P holders and Z filters in P holders, or the terrible Cokin adapter O362 that allow you fit only P filters, due to this non profitable searching I decided to design my own solution.
With this redesigned guides it's possible to use the Cokin P and Z filters in the Z-Pro holder, you only have to loosen the screws and slide the guide to the new position. In the left photo you can see in white the new guides, I test it with a 100x100 filter and it works like a charm.
I'm not sure if there are a lot of people with this problem, because of that I will not sell this new guides in the shop, I'll do something better I will give the design for free.
In the next link you can download the two STL files to print the guides, I recommend a good print resolution.
If you don't know where to print try to found a printer near you using the fantastic makexyz web.
