The Devil's Punchbowl, Ontario

Description

The Devil’s Punch Bowl is an unusually well shaped waterfall which falls over the Niagara escarpment. It is often no more than a trickle as it has a small area of drainage, but can be impressive after a few days of rain.

To reach it, take Centennial Parkway (Highway20) south off of the QEW Niagara, and follow it up the escarpment to Ridge Rd. on the left. Follow this road a short way around a bend and you will find a parking area on the left. You can also access a trail at the bend which will allow you to access the bottom of the falls, and you will pass a smaller falls on the way.

GPS Location: N:43.21130 W:79.75510

Warning: It can be dangerous to view and photograph waterfalls. The footing can be wet and slippery, and an accidental fall can result in serious injury or death. Note also that many sections of waterfalls are on private property. Please respect these rights.

Cascais, Portugal

About30 kilometers west of Lisbon is the town of Cascais, a popular tourist destination on the cost. The whole coastal area is well worth exploring.

It gained fame in the 1800s when it was used as a resort by the Royal family of Portugal.

The Temperate Rain Forest

Filed under: British Columbia, Scenic — Harold Stiver @ 7:00 am

Rainforest

When we hear about Rain Forests, most of us probably think of hot climates, and places like Ecuador and Costa Rica. However, the Northwest Pacific coast of North America also has a Rain Forest. This includes parts of British Columbia, Washington State and Oregon, as well as parts of Alaska and northern California, places which can have a generally cool climate.

What gives these places a Rain Forest is the coastal mountain ranges which create a high level of rainfall. This climate produces an incredible diversity of life, just like the Tropical Rain Forest does.

After a seabirding trip out of Belair, New Jersey a few years ago, I was able to spend a few early moring hours along the New Jersey shore.

I have been photographing wildflowers this year and my favorite lens for this is the Canon 180mm. It is extremely sharp and a great macro lens but it has a very shallow depth of field, so much so that it is usually not possible to get the close and far sides both in focus. An interesting solution to this is image stacking. This involves taking a series of shots with the focus changing from the front to the back and having at least one shot of each area in focus in one of the images.

The next step is to combine the images into a single image and this can be done in a number of specialist software programs. Among them are CombineZP (free program), Zerene Stacker ( free for now) and Helicon Focus ($30 but there is a 30 day free trail available). The image at the top is a stack of 4 images processed in Helicon Focus.

At this point I still have a lot to learn about this technique but it looks like a useful tool. Later this year I am planning on doing some extreme macros of insects and will probably need to use about 20+ images.

Here are a couple more results, both from stacks of 4 images.

Alpine Meadow

Some of the chairlifts at Whistler, British Columbia, operate during the summer and give visitors an opportunity to reach areas high in the mountains. The clear clean air shows these flower covered meadows at their best.

Sunflowers

Sunflower, Helianthus annuus

Artists and photographers seem drawn to Sunflowers. I find them irresistible. When I saw a large field full of Sunflowers yesterday, I had to stop and take some pictures. They are a native annual plant here in North America but that is a smaller plant than this large cultivated variety known as Russian Giant, more often seen.

Photoshop Tutorial – Secrets of the Crop Tool

Filed under: Photoshop Tutorial, Processing Tips — Harold Stiver @ 7:00 am

It seems simple enough. Drag the copy tool across your image, adjust the sides to your wishes and hit enter. You’ve cropped your image. But there is more. Here are a few uses you may not know about.

Keeping the same proportions

Keeping the same proportions

1. Keeping the same proportions

For many end uses, I find it useful to keep the same proportions as the original, usually 2×3 or 3×2. This is a simple task with the crop tool. Just hold down the Shift key as you drag the tool across the image and you’ll find that the crop has been restrained to the original proportions.

2. Do a perspective crop

You can change the perspective while you are cropping. After dragging your crop tool to create a marquee, you can click on the Perspective checkbox on the tool’s menu at the top. This allows you to shift any of the corners of the marquee, increasing or decreasing the perspective from that side.

Crop and Rotate

3. Crop and rotate

After dragging your crop tool to make a marquee in your image, you can rotate your crop before finalizing it. Just hold your mouse outside any corner and click and hold when the double arrow shaped courser appears. You can then drag your marquee in the direction you wish to rotate. Double click inside the marquee or hit enter to finish.

Hide your crop, don't delete

4. Hide your crop, don’t delete

I can find little real world use for the next secret of the cropping tool, but its kind of cute. It needs to be done on an image layer rather than the background, so double-click on the background layer in your layers menu to convert it. After setting your marquee, click the Hide checkbox and complete your crop by hitting the Enter key. If you change to the move tool (The up arrow at the top), you will find you can move the image around and the portion that was outside your crop will appear, as it was not deleted. I suppose this might be useful if you wanted to look at various crops of a certain size.

5. Crop to match dimensions of another image

Select the crop tool and make the image whose dimensions you want to match the active one. At the tool menu bar at the top, click on “Front Image”. Applying the crop tool to a second image will automatically provide a crop if the same dimensions as the first image.
