Hi all! This weeks lecture was about digital image management. I learnt about the different image formats you can store your images as, Print vs. screen and also image metadata.
I’m sure that many of you already know about the screen capture feature on your computer, but if not it’s a useful tool. It is a quick way of creating internet-friendly copies of images with a larger resolution. Most of you will know that you can use the snipping tool on your PC to do this. If you are using a Mac you can use grab. For this you simply press the keys CTRL + Shift + 4.
Image file formats are a way of organizing and storing your digital images. These files are made up of pixel or vector data or both. Bitmaps are a dot matrix data structure that represent a rectangular grid of pixels or points of colour and are viewable on anything you can look at images and I don’t just mean things in the digital world, who could forget about paper?! They map the image to bits which have values of zeros or ones hence the name bitmap. A bitmap is also known as a raster image and they can be stored in many different image file formats.
An intro to compression types
I mentioned in a previous post about saving a file in a compressed or uncompressed file format. If you do want to compress a file, Lossless compression allows you to compress the image without loosing any of the quality. If you wish to preserve the quality then this is the best option to go with however uploading a file like this to the internet could take ages!
Lossy compression is another option you can choose when you want to compress your files. This reduces the file size even more as it discards invisible information to the human eye. Most of the time you can vary the level of compression you wish to choose but if you compress your file too much, the image will become very distorted from the original.
There are so many image formats!
Here is a list of the different types of image formats with a little explanation beside each to help you understand the difference between them.
- PSD – This is a Photoshop file. When you edit your image in Photoshop, this is the first option to save your file as. This file type will always need to be supported by the version of Photoshop it was edited with.
- TIFF – Or its full name, tagged image file format, is a format for storing images that many graphic artists use. Again it is under the control of Adobe. This is an uncompressed file type.
- DNG – This is an open lossless RAW image format by Adobe. It is used for storing digital images. It saves the photo with a greater bit-depth and also a wide colour scope.
- GIF – The graphics interchange format is a bitmap image format. It allows animated images or just still images to be stored. Many of you will know what GIFs are from sites such as Reddit. It is suitable for storing things like logos that have solid areas of colour. Websites such as GifMaker allow you to create your own GIFs.
- PNG – This is again a bitmap image format that uses lossless data compression. This is the most used lossless format on the internet and does not require a patent license.
- JPEG – This is a compressed image file type and is usually used when you make edits to your pictures and then save. just remember the more you edit and save, the more you decrease the image quality. It can be a valuable way to store images you want to upload as it can create a very small file size.
When you want to upload images to the internet there are many different sites that allow you to do this. One of the most popular sites, which a lot of you probably know about, is Imgur.
Exif or exchangeable image file format is a standard that specifies the formats for images, sounds and ancillary tags used by your digital camera or your smartphone. It allows tags to be added to JPEG files, TIFF files and also WAV files. So when you take photos with the camera on your phone and it tags where it was taken, it can be found by anyone that looks up this tag. If you don’t want your image to be seen you can easily turn location services off on your phone.
That concludes this weeks post on digital image management. Remember to follow my blog and stay tuned for next weeks post on Social Media Tools!
Hi everyone, I’m back with another post! This weeks lecture was about preparing us for making an online digital presentation. Our presentation does not need to be done orally, so I will be designing mine in Prezi, an online presentation … Continue reading
Hi everyone! This weeks photography challenge was to take a photo from the website Retouch Pro and do one of the restoration challenges. I chose restore challenge 60 and soon realised it would be extremely challenging. It is my first time properly using Photoshop for retouching. The picture I chose had lots of detail that needed restoring in the face and also a lot of damage on it. I think for my first time retouching a photograph I have done well.
This is the original image:
As you can see there is a lot of scratches on the image and also a blue hue over the mans jacket. After starting this challenge, I realised that you would need to have knowledge of facial structure when editing this image to get the shape of the mans face right. However, I still wanted to give it a go and see how I would get on.
So this is what I have been able to do in Photoshop. There are still some scratches in the image but I had spent a lot of time to even get it to this and think I have done a good job for a beginner. To be able to get it to this stage, I first started off by cropping out some of the original image to make the area smaller to work with. I then applied the Dust and Scratches filter to it, to eliminate some of the major scratches across the center of the image. I used the spot healing brush tool for getting rid of a lot of the white dots around the image. I also used the healing brush tool on the faces as you are able to take a sample of some pixels from another area and then place them on the area I wanted to heal. This meant I could take areas of the man’s face that were the right colour and place them on his chin were the white scratch was. I used the smudge tool to smooth out the colour on the mans jacket and then I added two layers so I was able to adjust the levels of colour in certain parts of the image. I was able to use the magic wand tool to select the mans jacket on one of the layers and adjust that area on its own. As a beginner, I feel this was a touch challenge but I did enjoy it. If any of you have any feedback on how I could make some final improves to it please leave a comment below 🙂 .
Hi everyone! This weeks learning was focused on digital image editing. This was something I was looking forward to as I hadn’t used Photoshop properly before even though I have it installed on my laptop. The main topics for the week were opening, rotating, cropping and saving of images, retouching and colour correcting images, resizing and optimising images for the web and batch processing images.
All about photo editing.
There are many different programs that allow you to edit and manipulate an image. One of my favourite programs for editing and also one of the most well known is Adobe Photoshop. It is an editing program published and developed by Adobe. You suck at Photoshop is a YouTube channel which is very useful for learning how to use Photoshop as it can be quite confusing at first. Here is the link it can be found at. Photoshop is program you pay for, so if you can’t afford to use it, below are some free alternatives.
Gimp is the next program I would recommend for editing digital images. It is an open source program and free for everyone to use. You can use this program for things like photo touch-ups and image authoring. This is the link to the Gimp website where you can download the software for free.
Pixlr is another free program used for editing. It is an online program and can be found at the http://pixlr.com/ website. It is very simple and easy to use as it has a nice interface. It allows you to edit your images through the browser.
Picasa is the last program I will mention and is again a free editing software. I will explain in detail how to use this program as it is a nice and simple one to use. To edit an image you simply double click it to enter edit mode. In this mode, there will be tools to allow you to crop, retouch, colour correct and change effects in the picture. You can exit edit mode anytime by simply switching back to folder view. Picasa allows you to apply an effect to one image and then to every other image in that folder too. This is known as Batch processing effects.
It’s all very confusing! What are the most important parts of editing?
Here are some things that I feel are good to know as they are used in any editing software.
- The histogram shows the distribution of light and dark across an image.
- There are sharing controls to allow you to share your image to where you choose.
- The Crop tool allows you to adjust the size of your image.
- The Straightening tool allows you to straighten up your image for correct alignment.
- Colour correction allows you to adjust the highlights, mid-tones and shadows of an image.
- You can apply different effects and filters to your images with the effects tool.
This weeks photography task is to choose a photo from Retouch Pro’s touch-up challenges and edit the image. I will make a post on how I improved an image that was damaged from the options on this website, so keep following to see how I get on! Thanks for reading!
Well here it is! My finished podcast project for this module. I used an external microphone to record it and I edited the sound file with Adobe Audition. I decided to do a festival review of Tomorrowland, as I found it an easy topic to talk about. I hope you all enjoy it!

Hi Guys! For this weeks photography task we had to take a picture shifting between portrait and landscape to show how it can improve the framing of a picture. I went out into my back garden in the house to demonstrate this. After taking a few shots, I was able to pick up on a few different things. Here are the images I took.
Here is the landscape image I took. The landscape image is wider and has a view of the whole scene. For taking pictures like this, you hold the camera horizontally. Taking pictures in this format is usually better for taking pictures of scenery, as you don’t cut off parts of the view. You need to think about the composition and see if the scene will look better in landscape or portrait. I feel this one looked a lot better in landscape.
The second image here is the same scene except this time in portrait mode. The camera is held vertically for capturing an image like this. For a photograph of a landscape, I think it looks better in landscape orientation as this image looks cut off and does not capture the full scene. Taking a picture of a person can look better in portrait mode as it gets rid of distracting material in the background. Portrait orientation frames a picture which is good for head shots or close ups.
