TWIP Creating A Solar Filter DIY

I looked on line for solar filters for the upcoming eclipse and they were either top of the line filters that I would probably only use once in my lifetime or super cheap that got horrible reviews.  So, I started looking around at DIY possibilities.  I came across a guy that had built his own using a pair of UV filters and an order of solar paper.  He actually cut the paper and stuck it in between two UV filters, no glue.  (That could work, but I didn't want Vignette, but in hind sight, probably wouldn't have matter as it is going to be crazy dark anyway.)  I looked online and located a sheet of solar paper that was made by the same brand as a lot of the filters out there and decided to give it a go myself with a slightly modified idea.

Here is what you need:
I'll put a link to where I got these at the bottom of the post. If you get the 6x6 should be around $22.

Sheet of solar filter paper - I purchased the 12x12 sheet, however, I am planning on making three of these so I needed extra space.  

Step up filter ring - My lens has a front element of 77mm.  I decided to get the biggest step up I could find to have ample space for miscues.  I haven't been in kindergarten for a while and haven't practiced cutting with scissors in some time.  

Super Glue - preferably one with the little paint brush inside so you can just paint on the glue to the extra space of the ring.  

Now time to spend the 5 minutes and make one.

Do not take your filter paper out of the cardboard.  If you do, it is going to suck.  


The filter paper is neatly placed inside of two pieces of cardboard and you are going to use that to hold the paper in place as you cut.  It will make it easier and you will not fingerprint the heck out of the paper.  Finger prints are really hard to get off solar paper without causing other damage.


How I made mine.  

I took the step up filter and drew a circle around the filter on the cardboard as a cut out guide.  When you cut around the filter, be sure that the papers doesn't sneak out of the cardboard.  You also want to cut inside your circle a little ways as remember, you are putting it inside that circle.  

Next, take you put on some gloves or use a piece of lens cloth to remove the filter from the cardboard.  Place it in the filter to make sure that it is still not too big.  If so, trim accordingly.    Now that you have your paper and filter ready to go, it is time to start the gluing process.

I spaced my glue around the filter and didn't do a continuous path.  Not sure if that was the right route, but it is the one I took.  Now time to place the paper on the filter.  Make sure that the mirror side of the paper is facing out.  It will be the side that faces the sun.  Place the paper into the step up ring and let it dry for 10 or 15 minutes.  Please keep in mind that if you don't get the paper flat and smooth before it drys, you can take if back off and try again.  It comes off pretty easy.  Once dry, screw it onto your camera and go give it a shot.

Short story.  I attempted to wipe off the fingerprints while it was on the filter and it buckled which is why it looks like a bubble on the front of the filter.  Don't do that.  Use the lens cloth as instructed and you should be good.  Also, be careful with the filter as you can move, pop off, or smudge the paper.  The glue doesn't hold super strong.

TWIP Poor Man's 50 mm v 85mm v 100mm v 200mm Lens Test

I have a host of lenses I like to use on a regular basis.  I fiddle here and there with most of them not letting them gather a whole lot of dust.  Since upping the bar to a full frame I have found it interesting the actual lenses I use for the stuff that matters.  So I began getting the itch of GAS (Gear Acquisition Syndrome) again.  It may be that the camera that I have wanted was just announce or the fact that I have been itching for a lens for some time, but now am second guessing if I want to get rid of an old lens that I have and replace it with something a little better or possibly something totally new.  It's tough to distinguish, but I have been watching a lot of test videos of comparisons so I went through my stuff and didn't really have anything like this from my gear and how I shoot.  Now granted, I love my Canon 70-200 f/4 L IS.  It is the sharpest lens out there for a zoom.  I love it, but it doesn't get me to 2.8 which would give me lower light ability.  Now, I have lived with this lens for a long time and really don't feel the need to change, but I was interested in what 200mm compression looked like up against the lowest apertures on some of the other lenses I had.  Thus, I am going to give a go with a poor mans test of non-L lenses for my general thoughts and if I really want that shiny new 85 or a crusty old 135.  So, here are a couple shots of comparison.  I made my middle and littlest help me, which even though they got to blow dandelion seeds all over the yard, it didn't make them very up beat about the process.   I guess that 5 minutes could have been better spent.  

So I tested 4 lenses.  I have a 50mm 1.4, which is a really old lens and I would anticipate Canon upgrading any time in the near future.  I love mine.  It is very sharp even at 1.4 which most aren't.  I got a good copy.  I tested the 85mm 1.8., again, consumer lens but I really like mine.  Then tested one of my favorites, the Canon 100mm f2.8 macro lens (not the IS version).  This lens is also crazy sharp and I have no need for IS on this lens. I have never had the need to spend the extra $500 for the pretty red ring and IS.  Lastly, I tested my 70-200 f/4L IS at 135mm and 200mm just to see what it would look like and the bokeh (background blur) that would be shown.  I tried to maintain the same composition in all of the photos so I could see what the background was going to look like.  I think it did a pretty good job to what I was thinking.  Here is what I came up with.

50mm @1.4

85mm @ 1.8

100mm @ 2.8

135mm @ 4.0

200mm @ 4.0


The 200mm and 135mm area definitely show the compression of the background a make it to almost nothing.  I really wonder what f2 would look like at 135mm.  That is a lens I have looked at for a long time.  May have to borrow one and see what results I get.  I also really like the way the 85mm looks.  Still gives the roundness and less compression than the longer distances, but a nice blur with some inclusion of the background.  Now the lens I have been itching for is the 1.4 version of this lens that you can actually use at 1.4.  Canon does make a version with a 1.2, however that baby is expensive and for what I do, I can't justify the price.

The reason I am more interested in the 85 version, is I used to shoot primarily on a crop sensor with my 50mm.  If your shooting canon, the crop sensor has a 1.6x field of view of a full frame, meaning what your actually seeing is the lens distance x 1.6.  So my 50mm was actually much more like the 85mm lens on my full frame.

I think this little test made up my mind...now I just need to win the lottery.

TWIP - Who Knew Opossums Like Pizza Hut

So, I was lazy and set the pizza box on the deck table with a couple pieces of crust left over.  A few hours later we heard rustling on the deck.  The dogs and I were confused, so we went to check it out.  Much to our surprise was a visitor finishing off the leftovers.  You wouldn't believe how we were no more than 7 or 8 feet from each other, me and the drooling canines behind the patio door and him just hanging out on the table.  This baby opossum continued his meal watching our every move as I snapped away.  Once he finished up, he climbed off the table, left the deck and over the fence.

That time at Heron Haven

An adventure to Heron Haven this spring revealed some very interesting little creatures.  I was initially going to view the baby goslings but their mommies were a little more aggressive than I wanted to deal with being with my 4 year old.  We kept our distance and instead investigated snails, frogs, and turtles.  I didn't come very equipped, just my trusty 300mm f/4 so macro photos were very challenging.  I think we had a good adventure and learned a few things as well.

TWIP Steam Trains are COOL!

Having missed the first trip to town for the College World Series by a mere 2 minutes, I made sure I was in my spot in plenty of time to see the famous 844 steam engine of Union Pacific on its way back home.  Scouting spots along the railway turned out to be a good thing instead of the usual fly by the pants approach I tend to make most of the time when shooting things.  I reviewed spots along the line to get the best location, with little to no distractions in the background, and off the beaten path.  The first time around, there were cars lining the roadway and I knew this time wouldn't be any different as this was happening on a weekend instead of late during a work week.  That meant everyone and their dog with a camera were going to be out.  

I grabbed a location where it was a semi straight away just off the main road by a railroad crossing.  This way, as they were approaching the crossing they would have to blow the steam whistle.  This would cause steam to shoot up into the air from the front of the train.  I knew that it was warm, so the steam coming off the engine wouldn't be as dramatic as some of the photos everyone has seen as these are usually in the fall and winter when the weather is very cool.

So, I turned down my road and already there were multiple cars, video cameras, and kids hanging out to see the train. Luckily they were just off the main road and not in the area I wanted to be.  Pulling to my location, a couple other seasoned train photographers were there waiting as well.  Finding my spot, opposite of the others due to the clutter of the background, I set up the tripod, video, and got my telephoto ready to shoot.  Not knowing what to expect as this was my first time trying to shoot this engine, I didn't know of the speed or rate in which I was going to get an opportunity.

You can see from the video, this baby came fast.  I didn't have nearly as much time as I planned for  and the blew the horn a little sooner than I thought as well.  However, I came home with 3 shots that I am really happy with.  I have included those below.
