Greetings,I recently upgraded my computer from Windows 7 Home to Windows 10 Home using the free upgrade. The upgrade was successful but i wanted to clean install so i used the built-in recovery. If you are familiar with this, it also asks if i wanted to just deletemy files or CLEAN CLEAN install and i chose that. Took an hour or so and several more hours on 99% but it finished.My problem is that EVERYTIME i start my computer it automatically boots to Windows 10 and thats where it loads for about 7 seconds and then an error comes up stating that there is an INACCESSIBLEBOOTDEVICE.
If you drop down to 50mm, you're going to be limited to 5'5' height (portrait orientation) at 12' and 6'9' for the 15' foot length of the room. You're going to either have to get a FF camera, a larger studio, use an abnormally short focal length, or forget about doing full body shots.
What is focal length?In short, the focal length of the lens is the measure of how “zoomed in” your lens is. Much like looking through binoculars, you may be at 40 mm and be able to see an entire mountain, or zoom in to 400mm and only see one tree on the mountain.The focal length measurement tells the photographer what the angle of view will be. The angle of view means how wide of an area is visible in the picture. It also conveys the magnification of far-away objects in the photo.If you shoot at 20mm and the person you're photographing is 30 meters away, the person will be small (magnification) and you will see a lot of area around the person (field of view). However, if you zoom in to 300mm, the person will be large in the picture (magnification) and there won't be much scenery on the sides of the model showing in the frame (field of view).Focal length is measured in millimeters, but the measurement is not of the actual physical length of the lens, but rather the magnification properties of the lens.The actual measurement of focal length is the distance, in millimeters, between the convergence point and the imaging sensor. The convergence point is the point at which the light rays combine in the lens.
No worry, though, you'll never need to know that again. There's no pop quiz at the end.
Knowing the Focal Length of Your LensAll lenses show the focal length right on the lens. First of all, you'll see the range of the focal length that the lens can achieve in the name of the lens.
If your camera came with an 18-55mm f/3.5-5.6 lens, then you know that the widest your lens can go is 18mm and the most zoomed in your lens can go is 55mm.As you turn the barrel of your lens to zoom in, you can look at the scale on the end of the lens that connects to the camera to see what specific focal length you are shooting at.After you've taken a picture, almost all cameras will save the focal length information in the metadata of a picture. So if you want to go back and see what focal length you used to get a certain look, then you can go into the properties of the photo and see that.Keep in mind that not all lenses can zoom (change the focal length).
Some lenses are prime, which means they cannot zoom in. A common lens that cannot zoom (one which you likely own) is a 50mm f/1.8 lens.
It's a fantastic lens, but it cannot zoom in or out. The inner rectangle is the photo taken with a Nikon crop sensor DSLR, the full outer picture is taken at 18mm as well, but with a full frame camera. This shows that, AT THE SAME FOCAL LENGTH, a full frame camera is much wider. Focal Length and Crop FactorIf you shoot a crop sensor camera (Nikon D3300, D5500, D7200, or Canon Rebel, 70D, 7D, Fuji XT1, or Sony A6000 just to name a few), then your camera's crop factor will make your camera more zoomed in when compared to full frame cameras at the same focal length.So suppose I take a picture of a building on a crop sensor camera at 18mm.
If I put the same lens on my full frame camera and shoot at 18mm, the full frame picture will be much wider. However, I could easily get a 13mm lens and put it on my crop sensor camera to match the exact same field of view as the full frame camera.The point is that full frame cameras are not capable of shooting any wider or more telephoto than a crop sensor camera.
The difference just means that if the same focal length is selected on the lens, the full frame camera will produce a wider shot.Please understand that full frame cameras are neither superior nor inferior to crop sensor cameras. They both have benefits and drawbacks. I used to shoot a full frame Nikon camera, but ended up switching to a crop sensor Fuji XT1 camera which I'm really enjoying right now. Don't let anyone tell you that a full frame camera is better. It's simply different.I also want to make sure it's clear that you can achieve the same wide angle of view on a crop sensor camera as on a full frame camera just by using a wider lens, so there is no advantage to a full frame camera for landscape photography. And on the long end, it can be handy to have a crop sensor camera because it makes a 400mm lens turn into a 640mm lens without paying thousands and thousands of dollars on a lens that long.I wrote an entire article about, which you can read if this isn't quite sinking in yet. In this example with my lovely wife, I first stood VERY close to her and shoot at 10mm, then stepped back and zoomed in for each consecutive shot.
This keeps the size of her face the same in all the shots, but as you can see, the photo looks COMPLETELY different in each shot. NOBODY is going to look good in a photo if you shoot them with a wide angle lens from up close. Scoot back and zoom in when shooting portraits! Using a Proper Focal Length for Portrait PhotographyWider lenses show more distortion (unnatural bending of objects in a picture–especially around the edges of the frame). Also, the wider field of view of a wide lens (10 – 18mm) will make objects which are close to the camera seem much larger, and objects further from the camera much smaller.You need to understand that point to select a proper focal length for portrait photography. In the (horrible quality) animated gif above, I took four pictures of my wife from different focal lengths.
After each shot, I STEPPED BACK and zoomed in. By doing this, her face remains the same size in the picture, but as you can see, the photo looks COMPLETELY different!When on the wide end, you see much more of the backyard around her.
You see the side of the house, all of the fence, and you can't even see the trampoline because she's covering it. However, as you scoot back, you see much less of the yard (narrower field of view).

Also, notice that the face looks badly distorted when shooting with a wide angle lens up close, but as you scoot back and zoom in, everything looks normal and proportional.One last thing to notice, and this one is a bit more advanced, is that the background appears blurrier and blurrier as the focal length increases, despite the camera settings staying the same for all of the shots. To learn more about that, read my Choosing the Correct Focal Length for Different SituationsThere is no “right” or “wrong” focal length for any given situation. It's all a matter of personal preference and what you want to capture. However, there are certainly norms of the focal lengths typically used in different situations.All of the focal lengths below are the common focal lengths for crop sensor cameras, since the vast majority of the people reading this article will be shooting crop sensor cameras.
These are rough numbers, intended to give you an idea of what focal length you'd want). Landscape photography (10mm to 18mm). Full body portrait of a person (24 to 45mm). Headshot (55 to 140mm). Night photography (10 to 18mm). Close-up photography or macro photography (70 to 150mm).
Wildlife photography (200mm to 850mm). General lens for shooting family and kids (35 to 90mm).
Outdoor sports photography (200 to 400mm)Now that you've read through this handy cheat sheet of focal lengths for different situations, you should really consider checking out my free lens finder. It asks you 5 questions about what camera you use and what you want to take pictures of and your budget, and it gives you my personal recommendation of the perfect lens for you. Notice the HUGE difference between 10 and 15mm, but the tiny difference between 135 and 140mm. In fact, the 135 and 140 marks are so close together that you can't even tell them apart on this web-sized version. As your focal length gets longer, the difference in field of view is less of a change.
That's the front of my house, by the way. How Differing Focal Lengths Affect Field of ViewThere is one last thing you need to understand about focal length in order to have the basics under your belt. Here it is: As focal length increases, the change of the field of view decreases. As focal length reduces, the change in the field of view increases. Or in other words, there is an inverse exponential relationship between focal length and the change in field of view. Clear as mud?All this means is that on the wide end of your lens, zooming in 5mm will dramatically impact the field of view (how much scene you can fit into the frame).
However, when you're zoomed in tight, zooming in 5mm will only make a minute difference in how much scene is in the picture.If you understand this principle, it can save you a lot of money on lenses!
