Cosmicar Television Lens on OMD-EM1

I have had a Cosmicar video lens for quite some time. I never have used it for anything. I decided to purchase a C-mount adapter for micro 4/3rds and try it on my EM-1. It fits perfectly and works. Here are the specs for the lens:

Cosmicar Television Lens
25mm 1:1.4
Min Aperture 16
Focus 22ft to Infinity

It actually focuses a lot closer, maybe 15" on the EM-1.

I got my adapter from: C mount to micro 4/3 rds adapter

I had no problems attaching the lens to the adapter. No problems attaching the adapter to the camera. No I can get some use out of the lens.

Through the Viewfinder - TTV - for Kodak Brownie Reflex

I like grungy dreamy images. Photographing images through the viewfinder allows one to make this type of image directly with hardware, not later in software. This appeals to me.

I have a Kodak Brownie Reflex camera which has a nice sized viewfinder. It also has spots and dirt that makes for a cool image. I made an TTV adapter for the Kodak to use with my Olympus OMD-EM1. I constructed the adapter out of thick cardboard, like the back of a watercolor pad or something like that. I always save these pieces of cardboard for projects. The diagram for cutting out the shapes is shown below.

I glued the adapter together with hot glue. I also strengthened the adapter with duct tape. Below are some images of the finished adapter on the camera.

 Here is an example image take TTV.

Two Free Software Sites

I have always been a fan of free software. I recently have come across two excellent sites for free or almost free software. The first site is Shareware On Sale This site offers a new piece of free software almost everyday. A good many of the titles are of interest to photographers. I have downloaded resizers, pdf editors, image editors, and other interesting software. Usually, you have to download and complete the installation in the 24 hrs that the software is available. You get a valid license. Most does not come with support or upgrades. You can pay a little more to get that if you want. All that is required is that you create an account.

The second site is Bits du Jour. Again, there are many free giveaways, almost everyday. This site seems to have a broader range of titles of interest to a bigger audience. However, there are still many titles available of interest to the photographer. All that is required is that you create an account and like Bits du Jour and the software maker on Facebook. You can always change that later.

I frequently get useful software from both of these sites without issues.

Scanning Sofware - Paper Scan Free

I have been using PaperScan Free for awhile. I like the ease of use and functionality. However, in a recent update, They have added a splash screen about purchasing the pro version. I am ok with that. Only about 1/3 of the buttons to close the window are showing on my computer. I run Windows 7 and have not had this problem with any other software. When I use PaperScan Free, I have to click one of the buttons - don't know what it says - but I guessing it's about going to their website, because that's where I end up. After that the splash screen will go away. Really irritating. They have disabled the "X" on the splash screen, so you can't just close it.

I just remembered that FastStone Image Viewer has a twain interface. Think I'll switch to that and ditch the PaperScan Free.

Using the open source Inkscape Vector tool for Photos

Inkscape is a vector graphics editor. There are some features which I like to use on my photos. I like to use the some filter effects on my photos. I like the "drawing" filter quite a lot. You can find it at Filters-->Image effects-->Drawings. The filter has no adjustments, but I like it just as it is. Better than the PS and other similar filters. Other filters I like are pencil, and blue print. To use the filters, you must import an image into a document. With the image selected, apply the filter. Then you will need to export the image, using the File-->Import tool, and the File-->Export bitmap tool. This is a bit cumbersome, but worth it for me to use the effects.

Inkscape can also generate some interesting textures for compositing images. I have created numerous textures to use as backgrounds in my images. To do this, open a new document. Set up the document to the size you want using File-->Document Properties. Then place a square on the document to cover the whole page using the rectangle tool. Fill this rectangle with whatever color you want. While the rectangle is selected, choose Filters-->Image effects, transparent-->dots transparency. You will get a nice image like the one shown below.

Try using all the filters to create some nice free textures for your use in compositing.
