I'm so excited to announce that my first book, THE I HEART NAPTIME COOKBOOK: 100 easy and delicious recipes to make than less than an hour is now available for PRE-SALE! When we purchased our most recent camera, we opted to purchase our camera body with an 18-105 lens, rather than the standard 18-55 lens.  The price for buying the standard lens with zoom was a little more, but it is very convenient to not have to switch between lenses when at events that require both zoom and close up shots, and it helps keep the load in our bag to a minimum.  Our 18-105 lens and our prime lens are our two favorite lenses!  If you ever need help with deciding which lenses are compatible, definitely stop by and ask us!  I’d love to have you over for a visit anytime! Hi, I’m Jamielyn!Welcome to my blog.I Heart Naptime is a food and lifestyle blog sharing easy and delicious recipes, tips, crafts and entertaining ideas to help families create unforgettable moments. Green screen shooting (aka chromakeying) is the technique of shooting a subject in front of a green background and automatically replacing the background with a background image.
DSLR Remote Pro for Windows, NKRemote, PSRemote and Webcam Photobooth all support green screen shooting in stills photo booth mode and no additional software is required. Tungsten or fluorescent continous lighting is recommended for green screen shooting as this is easier to setup than flash.
The green screen background image can be any suitable JPEG image and should be placed in the photobooth images folder. The background and overlay images only need to be big enough to look good in the live view display and to print well e.g.
The background image should be named greenscreen_background.jpg and saved in the photobooth images folder. First click on the checkbox to enable green screen display and then adjust the sliders so that all of the green screen background is replaced with the background image but the foreground subject is unaffected. Users can be given a choice of backgrounds by saving each set of backgrounds in a different photobooth images folder and then use the profiles feature to switch between them.
The ready.jpg screens in each of the folders should be edited to show which green screen background has been selected. This script is designed to be used with an external numeric kaypad and allows the + and - keys to switch to the next or previous background and the other keys to load up to 14 different backgrounds directly. This script allows a three digit numeric code to be entered to select from up to 1000 different green screen backgrounds. The photo booth software only allows up to 8 profiles at a time to be defined but this doesn't limit the number of profiles that can be used.
For example suppose you want to offer the user the choice of 14 different green screen backgrounds this can be done be defining two pages of 7 profiles with a touchscreen action to switch between the two. Please note: The green screening is optimized for speed not quality in order to be able to display the greenscreened images in the live view window in realtime. Many photographers leave their camera on Auto mode and let the camera control the exposure settings. Every part of exposure controls the brightness of your image, and shutter speed is no exception.
Usually, a blurred background is a good thing because it eliminates distractions and makes the subject really pop out of the photo.

I got my first DSLR camera just over a year ago and I cannot tell you how much of a difference it has made. I personally have the Canon EOS Rebel T2i and 18-55mm Lens but I know the Canon EOS Rebel T3 with 18-55mm Lens is very similar and a couple hundred less. Jamielyn aspires to reach women, get their creative juices flowing, and to genuinely inspire.
Flash is harder to use because it is difficult to get the right lighting for both the live view images, which don't use flash, and the actual photos which do use flash. For best results the background and overlay images should be the same aspect ration as the photos being taken by the camera otherwise they may appear stretched or squashed.
An optional foreground overlay image can be used by creating a PNG image and saving it as a file named greenscreen_overlay.png in the photobooth images folder.
The easiest way to do this is to move the "Green threshold" slider to the left until most of the background is replaced and then fine tune the settings by moving the "Red level" and "Blue level" sliders to the right. For example suppose you have backgrounds from major cities around the world and would like to let the user choose which set to use you could create separate photobooth image folders for each city and name them something like London, Paris and New York. The photo booth software will detect that the background image has changed and will update the display automatically. By using the {photoboothDir} token to specify the profiles each photo booth images folder can have its own set of 8 profiles.
First create 14 photo booth image folders to hold the different backgrounds and name them folder1, folder2, folder3 etc.
Please note that this example is slightly more elaborate to the one described above as it allows up to 8 backgrounds to be selected from each page. The quality should be good enough for small photos and prints, but if you want large high quality results you may need to use specialist green screen software such as FxHome PhotoKey. However, you can be a lot more creative, and have more control over your image, if you know what the exposure settings mean. Each of these factors has a different effect on the image – each can make your image brighter or darker, and each has its own unique effect in addition to brightness. So it makes sense that in photography, aperture refers to the size of the opening in the lens.
When you change the camera’s aperture, they close or open to allow more or less light in. Depth of field can be explained many ways, but it’s basically just how out-of-focus (blurry) your background is.
This means that to get a fast shutter speed, you’ll need to turn aperture down lower. They aren’t cheap, but if you can put a little away towards one each month I would highly recommend saving up for one.
When she’s not creating, Jamielyn loves to chase her two little monkeys and snuggle up on the couch with her man.
Green backgrounds and background supports are available from professional photographic suppliers and online stores such as Amazon.
The green background should be placed as far behind the subjects as possible to avoid problems with shadows being cast on the background as these may cause problems with the green screen removal. You can make the background and overlay images larger, but this may cause a slightly longer delay when the photo booth software loads and resizes them.

The PNG overlay image should be a 24-bit color image with transparency information in the alpha channel. The best settings to use will depend on the lighting conditions and the quality of the green background. If you are using external buttons and a StealthSwitch II to control the booth you could program dedicated buttons to select each profile. The two AutoHotKey scripts described below provide different ways to select green screen backgrounds using a numeric keypad.
If each profile selects a different photo booth images folder it allows another 8 profiles to be used.
I’ll explain them in detail, then provide a handy reference chart at the end of this article. You can adjust the camera’s shutter speed on the LCD screen to the left of the f-stop (usually the top left of the screen, like in this image). If you look down the barrel of a lens, you probably won’t be able to see them, as they generally stay wide open unless you set it otherwise. This is great for sports, because it results in a blurred background (low aperture) as well as frozen action (high shutter speed). ISO 1600 used to be barely usable because of all the grain; now, photographers regularly use ISO 6400 and over, and 1600 is pretty much spotless. Removing noise does slightly decrease the sharpness of the image, but again, improvements in technology have made it very easy to remove a decent amount of noise.
It is available for stills photobooth shooting with DSLR Remote Pro for Windows, NKRemote, PSRemote and Webcam Photobooth. If areas of the subject show the background the settings are too strong and should be reduced by moving the red and blue sliders to the left of the green slider to the right. Alternatively you could use a touchscreen and define touchscreen areas to select each profile.
A highlight could be added to the currently selected background by editing the ready.jpg screen in each folder to make it easier for the user to navigate through the various screens. In this article, I’ll cover the 3 parts of the exposure triangle, and how you can use them to get better youth sports photos. The live view images shown to the user are also green screened allowing users to interact with the virtual background and see what the final photos will look like.
Then edit the photobooth settings to use the first photobooth folder, London, and save the settings as London.xml.
An optional foreground overlay image can also be used with transparent or semi-transparent areas.
Then press the keys on the keyboards numeric keypad (or use a separate numeric keypad connected to the computer) to select the 14 different backgrounds or press + or - to step through them.
The aspect ratio of photos from a webcam will depend on the webcam being used and the resolution setting. Different green screen backgrounds can be used for each shot in the photo booth shooting sequence - this is great fun at kids parties!
