Photojournalists have a saying, "f/8 and be there," meaning that being on the scene is more important than worrying about technical details. Yet with f/8, the depth-of-field and hyperfocal distance calculator for the iPhone and iPod touch, youll be there with the depth of field spot-on, too! Anywhere, anytime!
With f/8, all parameters and values are shown on a single screen with no scrolling required. All calculations are performed interactively in real time for maximum efficiency. The concept of camera bag provides fast access to the bodies, cameras, and lenses regularly used.
f/8 comes with presets for more than 800 camera models from Canon, Casio, Epson, Fujifilm, HP, Kodak, Konica, Kyocera, Leica, Minolta, Nikon, Olympus, Panasonic, Pentax, Ricoh, Samsung, Sigma, and Sony. There are also presets for various film formats (i.e., 35mm, 6x4.5, 6x6, 6x7, 6x9, 4x5, 5x7, 8x10), and cinematographic formats (i.e., 16mm, Super 16, 35mm). Furthermore, by choosing a circle of confusion (and, optionally, built-in lens) directly, camera models currently not listed can be user-defined. For lenses, f/8 allows not only the focal lengths to be specified but also their maximum aperture and minimum focus distance to conveniently adjust the range of input parameter allowed.
NOTE: f/8 does not use or manipulate the camera of the iPhone.
Pros and cons of f/8 DoF Calculator app for iPhone and iPad
f/8 DoF Calculator app good for
I like the lay out and ease of use. This is a great tool for certain photographic situations.
This app is easy to use, and works well for helping with composing landscapes. I wish that it went to smaller apertures (such as f/32) for some of my kit lenses. It would also be nice to be able to select from a database of lenses, or be able to input more lens properties.
I was previously using a laminated dof/hyperfocal chart for my 1.6x crop factor digital SLR. When I recently upgraded to a full-frame SLR, I realized I needed a new chart.
Fortunately I thought to check the app store for a dof calculator. This app was EXACTLY what I was looking for, and is much, much easier to use in practice than a chart. No mental gymnastics: just tell the app what body, lens, and zoom you are using and then fiddle with the aperture and focus point sliders until you get the hyperfocal point and dof you desire.
This UI was clearly designed by a photographer. Very, very nice, and even a couple bucks cheaper than the nice little chart I was using!
I think I have the f/8 all figured out except on thing. What is the lin / log in the lower right hand corner fo the window showing all of the data? I can not see where it does anything, but would like to know what is for.
This is a good app if slightly overpriced compared to the competition.
Watch out when scrolling a page as the variable sliders seem to attract focus and you end up moving one of them instead of the page... Extremely annoying to say the least...
Also I would have preferred a smaller font size and a more compact outlay and design in the main window in order to fit in all the info without having to scroll - The Hyperfocal Distance is at the bottom of the page and its a pain to have to scroll down to it - have a slider catch your finger swipe - readjust slider - and scroll down again...
So Mr Developer could we have 1 swipe fix and 1 refined outlay in next update please ?
Very handy. Does exactly what its supposed to do. Use it often in the field.
Some bad moments
F/8s product description led me to believe I was purchasing an APPlication that would add f/stop and shutter speed controls to my iPhone camera.
However, this product is only viable for calculation of f/stop and shutter speed for a broad range of digital camera makes and models.
Bitwerkz, never responded to my email which described the confusing product description, nor did they provide any explanation to why they could not
refund my purchase. ***HORRIBLE CUSTOMER SERVICE*** and ***MEDIOCRE PRODUCT*** ***DO NOT PURCHASE***
PS: I have worked in Film and Photo Production and Advertising for 12 years, and have a BA in Fine Art from FIU.
anyone know how to use this application wuold u be kind and showing how it works
I am a A list photographer... This is not what it clams or will give you what a f/8 lens will do. It confused me and I own high end bodies and lens.
Unfortunately, it has too many bugs an falls short. Dont bother programming in your prime lenses, as the app wont let you adjust the aperture with fixed
focal length lenses... for some reason, after I added a prime lens, I ended up with the same problem on all of my other lenses... I currently have 2 DSLR bodies programmed in, along with 2 16mm cine cams and 3 hdv cameras, and none of them calculate properly when paired with any lens since I added my 50mm prime lens... a huge disappointment for 4 bucks, but once this is fixed its so worth the money!
This app needs a more precise way to enter exact figures for distance and f-stop. THIS APP IS INCOMPLETE without the ability to type in distances. As a Director of Photography, my camera operators measure and log exact distances. Having to scroll tediously to get calculations with these numbers is counterintuitive, wastes time, and takes my focus away from the shot.
The sliders are good when you can change camera settings or subject distance for your shot to get the depth you want. But in cinematography, when you cannot always adjust the f-stop or move the camera, you just need to know what you have to work with. When this happens, the sliders get in the way, as the distance and f-stop are fixed. This is why truly professional applications have multiple ways of entering the same information; each method helps with a different paradigm of thought.
That being said, the camera bag functionality is unique to this app. Its a fantastic feature; one that is true to how photographers and DPs work.
This app would be worth 4 or maybe even 5 stars if it werent for the slider controls used to enter focus distance and aperture. Not only are they hard to move accurately but most of the time they just wont move at all. If I had my way, these things would be banned from any app that requires even minimal precision. If this had roller wheels to set the distance and aperture, I think Id really like it but as it is, its pretty useless. I only gave it 2 stars for potential. Goodbye $3.99.
