Make your images outstanding using iPhoto effects

iPhoto editing features can make an ordinary photo extraordinary

This is the next installment in the iPhoto series.

One of my cats, Cordelia, agreed to help out with this post. Gorgeous as the subject is, the image is a bit dull; there’s not much color and the background could have been better. And, I unfortunately cut off the tip of her right ear. But she is worthy of rescuing with iPhoto!
Original image

Before I begin I’ll make a copy of the image.

Open the special effects windows

In this iPhoto edit we’ll combine a few special effects features. So, select Edit and open both the Effects and Adjust options.

iPhoto toolbar

Move the special effects windows to either side of the image so you can see the changes as you edit. The editing sliders in the Adjust window are all at the default settings and you should already see the special features from the thumbnails in the Effects window.

Adjust the levels to brighten the image

Adjusting the levels is always my first step when editing. Sometimes a slight levels adjustment is all a photo needs. The left-hand slider controls the darker tones and the right-hand slider controls the lighter tones while the middle slider helps to balance the brightness and shadow. Play around with the settings to see which best suits your image. I moved each slider for this image. I also slightly increased the Exposure (to 0.24) and bumped up the Contrast (to 20)

See the difference these changes have already made. The background is more washed out and Cordelia is more prominent.
Change the levels and exposure and contrast

But, we can do more.

A tiny retouch

In the original photo do you see the tiny blemish under Cordelia’s right eye? It looks like I took the photo before she had finished grooming. Using the Retouch tool, I moved the slider to roughly the size of the blemish and simply clicked over the spot to remove it. Much tidier.

Clean up the image with the retouch tool

OK, let’s adjust those settings.

Add some warmth and saturate the colors

The Temperature slider can cool down or warm up your picture. In this instance, we want a bit of warmth so I moved the slider to the right (set to 6.5). This has changed the colour of her eyes to the correct shade of gold. The picture still needs some more color so I slid the Saturation to the right (up to 61). To remove a bit of the darkness on the fur I moved the Shadow slider up (to 6.1).

Each change is small but significant.

Boost the colours

A crop and a matte finish

Cordelia’s is looking slightly more reddish than she should be (well, she is a Chocolate British Shorthair after all, not a Reddish British Shorthair) so even though her eyes are now a more true to life colour, I added a slight Tint (to 9.8) to tone down the reddish fur and bring out more of the chocolate color.

Now to the Effects window, I selected Matte. Then a slight Crop to finish. Why the crop after the matte and not before? I did try it that way but the crop was too tight and the matte finish covered part of the cat in white. So I added the matte and then did a couple of crops to get it just right. Having said that, the matte does help disguise the fact that the tip of her right ear was clipped.

Et voila!

Duplicate an image in iPhoto

Sunday, March 2nd, 2008

Always make a copy of your original image before adding special effects.

Quick tip

To make a copy of your photo before you start post processing use the Duplicate option located on the toolbar under Photos or by selecting Cmd+D.

But iPhoto won’t let me click ‘duplicate’

Making a copy of an image can sometimes seem tricky as the Duplicate option isn’t always ‘clickable’. This is because you can’t perform this action when you select an image from a Smart Album.

I recently discovered this after I sorted all my photos into various Smart Albums. Using Smart Albums is an excellent way to organise photos, but because it’s not a real album (they are based on criteria you specify such as keywords) some options are not available to use.

So, if you find you can’t duplicate an image make sure you are not in a Smart Album. Simply browse to the image from a regular album or from the Photo Library option.

How to resize an image in iPhoto

Monday, January 14th, 2008

In iPhoto, resize an image when you export it to be used in another application

Resize a photo using the export option

Emailing a photo or posting an image to a website (such as the ones in this post) don’t need to be large files. In fact, a lower resolution is preferable so you don’t crash your friend’s email program or create a webpage that takes a lifetime to load. Resizing an image will reduce its resolution and hence its file size.

There are two options to resize a photo using iPhoto.

Option 1: A simple but effective way to resize and email a photo

Select your image and choose the Email button at the bottom right corner of the iPhoto window. This pop-up box will appear:

Email option

The one option you have is to select a file size: Small, Medium, Large and Actual Size. You don’t have the option to select a width or height, but the pop-up will display the file size for each option you select. The smaller the file size the quicker the photo will download to the recipient’s computer.

Select Compose and the Apple Mail program will open for you to write and send your message. This is the most basic option and will only be useful if you use Apple Mail.

Option 2: For more control over resizing your image in iPhoto follow these 3 steps

Step 1 - Choose your image

Select your image and choose File -> Export. A pop-up window with three tabs will appear.

File export options

Step 2 - Select a file format

On the File Export tab there are several options you can change - you want the Kind and Size options. The Kind option has five file formats to choose from. Three of these allow you to resize the image: JPEG; PNG; or TIFF. If you select JPEG (a common format to email) you also have the option to select an image quality, ranging from low to maximum, and this will affect the final file size of the image.

Step 3 - Select a size

On the Size option you can simply select Small, Medium or Large, but if you want a specific size select Custom. This is my preferred option.

Image dimensions

If you choose Custom select a specific height or width. Click Export and save the image to a location on your computer. And that’s it!

Example of the various file sizes

If you are concerned about the file size of your exported image here’s an example of the different options on one of my photos.

The original dimensions of this image below are 1928 x 1427 pixels with a file size of 1.4 mb. That’s too large a file size to email or add to this post and you would need to scroll across the page to see the entire image. My preferred image size for this website is 400px.

Strawberries

Custom resize

Resizing the original image to a 400px JPEG breaks down to the following dimensions:

  • maximum quality = 184kb
  • high quality = 44kb
  • medium quality = 28kb (this is the one I’m using above)
  • low quality = 16kb

Small, medium and large sizes

If I simply want a small, medium or large image (without using the custom option) the original image would become:

  • full size = 436kb with the same dimensions
  • large = 192kb at 1280 x 947 pixels
  • medium = 56kb at 640 x 474 pixels
  • small = 20kb at 320 x 237 pixels

Remember…resize on export

I have to admit this resize option in iPhoto hid under the radar for me for a while but it’s actually a very simple process. Having the resize option available when exporting it from iPhoto makes sense. And most importantly, resizing an image on export leaves the original version intact.

Add special effects to your images with iPhoto

Enhance your photos quickly and easily with the versatile effects in iPhoto

I previously wrote about using the tools in iPhoto to edit your images. In this article, I’ll explore the special effects that are available in iPhoto which let you make changes to your photos in just a few clicks.

So, let’s see what cool things we can do with an ordinary image.

In iPhoto, select an image, however ordinary… Actually, I quite like this photo. You can see where the sun hits the tree branches at odd angles.

Sloping tree

Click the Edit button and select Effects.

The Effects box

iPhoto Effects options
The Effects box gives you thumbnail previews of what your image will look like with each special effect. Simply click an effect to see an immediate change on your image. If you aren’t happy with the changes you’ve made click the center icon to restore the image to its original colors.

Looking at the thumbnail icons for this image I am instantly drawn to the Sepia option. The tree takes on a sunburnt aspect and the sunny background looks as though there could be a fire looming.

Sepia toned tree
That makes a difference to the image…but it’s still not quite right.

Mix and match the special effects

The sepia tones look great and the sun bouncing off the branches really stands out. But let’s try mixing and matching the options to achieve a better result.

A color boost with the sepia tones might just do the trick.

Intensify the special effects

It might be too small to see in the image above but on the Boost Color thumbnail the number three is visible. I clicked the color boost option three times; it can be clicked up to nine times. Check out the image below, now the sepia combined with the color boost (at number nine) looks like a sunset…or a very fierce fire.

Choose effects that are right for your image

With a little experimentation you can really make a difference to your photos using the iPhoto special effects.

The Antique option combined with an Edge Blur brings a lovely nostalgic feel to this photo (below).

Antique Bees

This combination of Matte and Vignette (below) enhances the view out of an aeroplane window.

Experiment and admire your new images

So, back to the tree. I’ve settled on the sepia tones with a color boost of four. Click the image to see a larger version in Flickr.

Use the tools in iPhoto to edit your images

Enjoy the power of iPhoto without buying expensive imaging software

The more I use iPhoto the more I love it. There are so many useful tools in this image editing program and I have realised I rarely use other photo editing software for these enhancements. It has been a personal mission, recently, to get the most out of iPhoto and online image editing tools to see just what can be accomplished without having to resort to the more expensive imaging software (I still use PhotoShop to learn the more intricate post-production techniques) and iPhoto has a lot to offer.

Of course, in a perfect world all the photos we snapped wouldn’t need any retouching at all…

In this article, I’ll focus on some of the tools you can use in iPhoto to improve your photos in just a few simple steps.

First, get a Mac!

Mac users are lucky: iPhoto is powerful without being difficult to learn. As with most of these things it simply requires a bit of exploration and experimentation. I won’t talk here about the ease of importing your photos to your computer, sorting them into albums, creating smart albums or making slideshows. I want to focus on editing your images with iPhoto, especially retouching, cropping and straightening.

Second, get an image

Take this image, for example. While it might not be the most creative of images, it happens to be a photo of one of my most favourite houses that I walk past quite regularly. There’s an intriguing mix of spookiness and tranquility.

Original image

So while the subject of the photo is interesting, the image itself could do with some improvement. Look at those telephone wires! And the corner of that car. And…isn’t the house a bit crooked?

Third, use the iPhoto tools

Retouch

Double-click the image and hit the Edit button. Select the Retouch tool. You’ll see a new option appear on the image that says Click or drag over blemish to remove and a Size slider.

Retouch options

The size of the retouch tool depends on the area you wish to retouch. As I am removing telephone wires here I chose a relatively small size. Once you are happy with the selected size you can click and drag it over the area to be retouched. This worked really well with the telephone wires. In the image below you can see that the click and drag effect seems to white out the blue background.

Retouching with iPhoto

But as soon as you release the mouse button the background appears as desired. Below you can see the start of the disappearance of the telephone lines.

Editing with iPhoto

Straighten

What else? The house is crooked, isn’t it? Once again in Edit mode click on the Straighten tool. Grid lines appear over the photo making it nice and easy to straighten the subject. I lined up the front eaves of the house with one of the grid lines.

Straighten the image

Crop

Lastly a crop to get rid of the car and to remove any unnecessary distractions from the house and we’re done!

Fourth, admire your new image

Here’s the final image.

So as you can see with a few simple steps you can really make a difference to your photos.

iPhoto has much more to offer and we’ll explore other tools in future articles.
