Flash Alternative for Pet Photography

One of my most used Christmas presents this year is a Viltrox LED Light Panel. I picked it out after my wife said that my stepson was looking for something to buy for me. I am very hard to buy for because I don’t need much and if I do find something that I want it is too expensive for me or anyone else. So you can imagine how hard it was to come up with a good suggestion. I was very happy that it actually was a good suggestion because this light has proved to be quite useful.

I typically hate using a flash for photographing our cats, or anything else. About the only thing a flash is good for, in my opinion, is in photographing receipts. I hate the harsh shadows it creates and you just can’t avoid those laser eyes.

This light panel is not better than natural light but it does improve on the flash that comes on your camera in five significant ways.

  1. It has a much larger surface area than a flash so it does not produce the single direction light that causes harsh shadows. Of course, it is not as diffused as the large studio lights in a portrait studio but it is much more portable and less expensive.
  2. The color temperature can be changed to match the lighting conditions. If you are outdoors and need a fill light, you can set it to a higher color temperature to match the natural light. If you are indoors and want the warmer light that you get from incandescent bulbs or candle, you can turn down the color temperature to a warmer level.
  3. The brightness level can be set between 20% and 100% intensity. Sometimes I just need a little fill light and I don’t want my subjects to squint when I take their photo so I turn the level down to 40% or less.
  4. The light does not need to be attached to the camera so you can get extra light from whatever angle you need it to come from.
  5. By being constantly on, it gives the eyes a chance to dilate, thus reducing red eye or “laser eyes.”

I took the two photos below with the light attached to my camera. The first one of Chris sleeping on the sofa is a good example of how the light does not produce harsh shadows. I wish I had taken another photo using the camera’s flash but I did not think of it at the time.

This photo of Chris does have some obvious shadows, which were unavoidable given the content, but I have shot photos like this using a flash and they are almost always unusable. Pay no attention to Chris’s eye boogers. That has always been a constant problem with his eyes.

What do you think? Do you have any other lighting tips you would like to share?


My Wife, the Cat Photographer

The other day my wife, Rose, decided to give her iPad to her sister since she never uses it anymore. She asked me to remove all of her information but when I started to do that I noticed she had over a hundred photos, many of them were pictures of our cats from 2016.

I wanted to transfer the photos to my desktop computer but I was reminded over and over why I hate Apple. They have a reputation for being easy but I have always found the opposite to be true. I couldn’t access the files by plugging the iPad directly to my computer so I uploaded them to iCloud but when I tried to access them on my web browser I was informed that only an Apple device could view them.

I could go on and on but I eventually got the photos and I want to share some of them with you.

This first one is Frankie doing what Frankie does. It is a bit grainy, probably because of poor lighting.

The next one is Frankie on one of his favorite napping spots; our printer. I have since put a towel over it to make it more comfortable.

This is Floki the day after we adopted him.

Here is Frankie again. This was shortly after we adopted Floki and everyone picked up an eye infection from him. I think it was also the first time Chris went to the vet for a medical issue.

Floki again five weeks after adoption. Notice his brown color is coming in.

My wife works from home a few days a week. In this photo, she is with another person that I don’t know and had to crop her out. It looks like Chris is helping her here.

The next photos are of Chris at the vet for an eye infection that he got from Floki. I won’t include those because I already posted them. You can see them here.

Here is another example of how helpful Chris is to Rose. I’m sure she gets a lot more done when Chris is around.

These next two were taken on the same day. The first is my favorite. It is Frankie and Floki enjoying the sunbeam.

Here is a photo that is grainy but it includes all of our boys.

What do you think? Do I need to worry about my job as blog photographer?

Basic Photography for Bloggers

When blogging was young it was mostly about the words but now images are a major part of almost every blog I see today. I consider photos to be very important on this blog, partly because they help to tell the story. With that in mind, I want to share some of the things have learned over the years.

Photography is all about collecting light and there are three major components that help you do that. Each one has its own advantages and disadvantages. I’m talking about shutter speed, aperture, and ISO. Each of these can be adjusted to help get the right amount of light for a good exposure but knowing which ones to adjust is a challenge because there are so many factors to consider. Let’s start with aperture.


Aperture is simply the size of the opening in the lens. This is also referred to as an f-stop. I believe the “f” is for “factor” and it is a ratio of the focal length of the lens to the diameter of the opening, or pupil. For example, on a 50mm lens f-11 would be 50/11 or 4.5mm. An aperture setting of f-1.4 would be 50/1.4 or 35.7mm. The important thing to remember is that the smaller the number the larger the opening.

The size of the opening matters because whenever you double the size of the aperture you cut in half the time it needs to stay open for a proper exposure. Some lenses are considered “fast.” These are very expensive but have apertures as wide as f-1.0. Some are even wider than that. These are good for very low light conditions or when the shutter speed needs to be very fast.

Of course, for every plus in photography, there is a minus. The larger the aperture, the smaller the area that will be in focus. To understand why let’s look at a pinhole camera.

Source Wikipedia

This is the most basic type of camera where a pinhole is made on one side of the box and photographic paper placed against the other side. To get a perfectly sharp image, the pinhole would have to be no wider than a single ray of light, but that would let in so little light that the exposure time would be extremely long. A larger opening would shorten the exposure time but then the light coming from the top of the tree, for example, would enter the opening through the top of the hole, the bottom, left, right, middle, etc. The light would then strike the film at slightly different spots causing the image to be out of focus.

The camera lenses solve that problem to some degree but they create instead a focus zone. That essentially means that one area of your photo, your subject hopefully, is in perfect focus and a certain area in front and behind is in acceptable focus. The rule of thumb is one third in front and two thirds behind. This zone of focus is also called depth of field. The important thing to know is that the smaller the aperture, the larger the depth of field.

Below is an example of a photo with a small depth of field. This is Frankie and Chris taken using an f-2.2 aperture. Notice how Chris is close to Frankie but still out of focus. Sometimes this is desirable. I think this photo works well with just Frankie in focus.

I took the photo of Floki and Chris below using a smaller aperture of f-7.1. Notice how much more is in focus. Even the car in the background is relatively sharp.

A larger aperture would have made the photo better by blurring out unimportant parts. To get that larger aperture I would have also had to increase the shutter speed which, in this case, would not have hurt the photo. I will talk about that in the next two sections.

Shutter Speed

A shutter is basically a light-proof “curtain” between the lens and the sensor. It slides open to allow light to reach the sensor and then closes after a given amount of time. That time is called the shutter speed and can range from several seconds to 1/4000th of a second. The shutter speed serves two basic purposes. It varies the amount of light reaching the sensor and it can blur or make sharp a moving object.

This is kind of important to know for pet photographers because it is difficult to keep them still while you try to take their photo. Granted, if they turn their heads as you are about to snap the photo, shutter speed won’t help but it will prevent small movements from becoming blurry.

Sometimes you want the blur. A good example would be when you are tracking a moving object across your field of view and you want to convey a feeling of movement in the image. The photo below is an image I took years ago of my friend riding by on his motorcycle.

The shutter speed was just slow enough to cause blur in the background from the movement of the camera but since my camera was moving with the subject it stayed relatively sharp. This effect gives the viewer a feeling of speed.

Another reason you would want a fast shutter speed is when you are hand holding the camera. This is especially true when you are using a telephoto or zoom lens. A telephoto lens turns a small camera movement into a large one so a faster shutter speed is needed. The rule of thumb for 35 mm film cameras was that the shutter speed should equal the focal length of the lens or faster when you hand hold the camera. Now, with different size sensors and image stabilization technology, it is difficult to suggest a rule of thumb. It is probably best to check your camera’s manual for tips on this subject.

One other thing that could be useful to know is your “flash sync speed.” This probably won’t apply to anyone using your camera’s built-in flash but if you use an external flash there is a limit to how fast your shutter speed can be. Not every camera is the same so it is good to know what your camera’s sync speed is.

To understand how this works, imagine a stage where the curtain is closed but instead of the left and right curtains both being pulled to the middle, the right curtain is pulled all the way to the left. That curtain is then pulled to the right to expose the stage and when the show is over the left curtain is pulled to the right to close it. Once the audience goes home, both curtains are pulled back to the left for the next show.

A problem with flash photography occurs at higher shutter speeds. To go back to our stage analogy, when a show is very short, like 1/500th of a second (some shows I wished that was the case) the stagehand operating the left curtain starts closing his curtain 1/500th of a second after the other stagehand started pulling her curtain open. Since it takes 1/125th of a second for a curtain to travel across the stage, the entire stage is never in view at one time.

A flash is much faster. It varies but most often the flash speed will be between 1/5000th and 1/30,000th of a second. That means when the flash goes off only part of the stage will be illuminated.


ISO stands for International Organization of Standardization. This originally represented the “film speed” or its sensitivity to light. I remember it being called ASA (American Standards Association). When shooting film the photographer had to buy different types of film for different lighting conditions. On a digital camera, one can just change a setting.

The ISO number represents the sensor’s sensitivity to light. The higher the number, the less light is needed for a shot. For example, shooting at ISO 100 requires twice as much light as shooting at ISO 200. So why not just shoot everything at the highest ISO? Because every plus has a minus.

During the old days of film, high ISO film meant grainer images. Some photographer’s used that graininess to their advantage but mostly it was a necessary evil. On digital cameras, a high ISO setting results in images that have more digital “noise” that is similar to the old film grain.

Below is a photograph of Frankie shot at ISO 26,500, the maximum for my camera.

Notice the grain, or noise, when viewed close up.

Compare that to a photo of Chris at ISO 100.

See the difference? The above photo of Chris was cropped but both close-ups are at the same magnification.

Besides the major three settings, there are others that you can play around with, like white balance and HDR, but I want to stick to the basics here.

Since this post is for bloggers I want to talk about file size. Internet speeds and storage space have increased over the years but file size is still important on the web. People are busy now and will not wait more than a few seconds for your page to load so if you have a lot of photos, they should be as small as is reasonable.

There is also storage space provided by your web page hosting service to consider. If you exceed your limit you will need to pay for more storage. WordPress.com gives me 3 gigabytes of storage and so far I have used 37% in over six years of blog posts. If I uploaded my photos full size, that would have been gone long ago.

Conser this: My computer monitor’s screen resolution is (in pixels) 1680×1050. The highest I have seen is 3840×1600 which is 4K. Many are probably the same as an HDTV which is 1920×1080 and there are some older ones that are smaller than mine. Smartphones have similar resolutions but on a much smaller screen. There are 8K monitors coming out but since most blog traffic comes shortly after a post is written I wouldn’t even consider those now.

I chose long ago to use the old XGA resolution (1024 x 768) on most of my photos on this blog. Since the photo never takes up the entire screen, I thought that was a good compromise. I use the canon software that came with my camera and save a copy of the photos I will use to 1024 pixels on the longest side, a little less for square photos.

There is also a quality adjustment for jpeg files that can reduce the file size even further. My program allows a choice between one and ten with ten being the highest quality and largest file size. I choose seven because I don’t notice a quality difference at that level but I do notice slight degradations at level five.

I should note that I treat my photo blog a little different because I only use one photo per blog post and I want it to look good so I reduce it to 1200 pixels with a quality of nine.

I think that should cover the basics. If you have any questions or comments, I’d love to read them.

Photographer’s Assistants

Rose and I have been trying to sell a few things on eBay these last couple of weeks and my job has been to take the photographs. I remembered I had a couple of white boards for matting photographs and thought I would use those for a background. I laid one flat and propped the second one at a 90 degree angle. Once I did that the cats were all over it like I just introduced them to a new kind of catnip.

Of course there was competition and conflict.
