Google are now giving away their Nik Collection plugins for Photoshop and Lightroom free of charge. These are an excellent set of plugins and at the current price who wouldn't want them. 

You can get them on this page while the offer lasts

You get the full collection of:
Analog Efex Pro. A filter that recreates a traditional film and lenses look
Color Efex Pro. A comprehensive set of filters for color correction, retouching, and creative effects.
Silver Efex Pro. One of the best colour to black and white conversion filters. 
Viveza. Helps you selectively adjust the tone of your images.
HDR Efex Pro. An excellent tool that helps you create HDR (High Dynamic Range) images in Photoshop.
Sharpener Pro. An advanced filter that helps you fine tune the sharpening of your images.
Dfine. A filter that removes noise from your images. Like the other filters you can apply the effect locally or over the entire image. 

While it's great that these professional grade filters are now free I wonder if it means that Google are going to stop developing them and leave them to rot. It won't be the first time they've bought out a company, used parts of their technology that they like and dumped the rest. 

I thought I'd give the Capture Pro with the Arca Swiss plate a try as a reputable company were offering quite a good discount at the moment on one. They are probably offering a discount on the Arca Swiss version of Capture Pro because Peak Design are discontinuing the plate. I'm not sure why they are discontinuing the Arca Swiss only plate in favour of the dual Pro Plate, personally I would much rather have the Arca Swiss plate (which is what I got). The dual plate does have the advantage of being able to be converted to use on Manfrotto's RC2 quick release system I suppose.

If you get the Pro Plate you have to screw two little adapters into the side of the plate so it will fit a Manfrotto RC2 head. Without the adapters it is an Arca Swiss only plate. Putting the adapters on is only useful if you have a few Manfrotto RC2 heads around that you'd like to attach your plate to. You don't have to put the adapters on if you don't need them, so I guess the logic at Peak Design is that you get the best of both worlds with the Pro Plate and they don't have to make different plates. You should note that the Pro Plate won't work with other manufacturer's own brand quick release systems. ​

Once the adapters are on, although it means you can mount the plate on both an Arca Swiss head and an RC2 plate, you can only do it from two directions instead of four directions because the plate will no longer be square. You might find this to be inconvenient. Also it won't work with all RC2 heads.

One thing you can do is to convert your Manfrotto heads to Arca Swiss which is the way to go in my opinion but this might get expensive if you have quite a few RC2 heads around. If you've only got one or two then you can buy either a very inexpensive Chinese Arca Swiss plate, use the reasonably priced FotoPanda (Desmond in the USA) plate or go expensive with a Really Right Stuff plate

I might really take to using the Capture Pro or it might just end up being something that gets put in the back of my gear drawer and pulled out now and again. 

It will be something I can also use with my Go Pro and if I buy the new Peak Design Lens Kit that works with Capture it will be very useful indeed. In fact the Lens Kit is something I can really see myself using. 

Mounting the Capture Pro to the top of a monopod might be a cool way to use it too. I won't be able to do portrait orientation with it if I stick it directly on the monopod. I don't currently need to be able to screw it to my monopod but it's handy to know it can be done and I might find it a useful way of using it.
