Tip: Work in full screen

26 07 2009

When you are working on a photo (either for making a selection or doing some editing), work in full screen. This prevents other windows, menu bars, desktop backgrounds from distracting you. Working in full screen mode changes how you perceive the image. This is especially true if there is a big clash between the colours of your image and that of your desktop. Your image needs space around it. This is also something to keep in mind when you display your photos somewhere.

Happy shooting.

Learning photography: assignment 2 sharp

15 07 2009

If you read about photography, you’ll often read sharper this or that. How to get sharper pictures that this is a sharp lens. In this assignment I want to explore sharpness in photo’s. How do you see sharpness in a photo? How does it influence the photo as a whole? How can you influence sharpness? How does it relate to focus etc etc.

Task: Experiment with sharpness

In about a week or two I’ll share with you what I’ve learned. If you are learning with me let me know what you’ve learned by adding it in the comments.

Happy shooting!

Learning photography, results assignment 1: light

11 07 2009

In a post two weeks ago I set myself an assignment:

Task: take a subject easy to reach and take many pictures of it at different times of day, so from dawn till dusk. Compare the results and see how the subject changes.

Here is the result of that assignment and what lessons I’ve learned from it.

I started out this assignment with the knowledge that light is important and that the best time of day to shoot is around the hours of sunset and sunrise. If you are anything like me, this kind of knowledge only really sinks in after you’ve seen it with your own eyes. I took photos of a leaf covered chimney which is visible from my apartment. The pictures are taken with the same camera and without any level adjustments. I will draw your attention to some aspects which got mine. Click the images to get a larger version. With each picture I added the RGB histogram. (click here to read about histograms) So without further ado, here we go:

06histogram1

This image is taken about 1 hour after sunrise. It has a lot of details in the leaves. The histogram shows a bit of blue being washed out, but all in all fairly balanced.

09histogram2
This image is taken about 4 hours after sunrise. Notice the vibrancy of the colours. Morning sky is in general more clear. There is however less detail in the leaves, it looks a bit more like a green blanket rather than individual leaves. This is also because the sunlit part is lit from the frot as opposed to lit from the side.

11histogram3
We are now 6 hours after sunrise. The contrast between the sky and object start to increase, and detail start to be lost. Also notice that due to the fact that the sun has turned. The light comes more from the sides. This reveals some relief in the leafcover.

histogram3half
Seven hours after sunrise closing in on midday. Notice how the left peak in the histogram (the object) start to be very narrow. This means less detail. Compared to the previous image the shadow side of the chimney has darkened (or the sunlit side and the sky have brightened).

histogram4
Midday. Out is the detail and the blue sky is the same go. The histograms shows a narrow band on both sides. In short not a great time to take pictures.

histogram5
Now we are moving to sunset. This is about 3 hours before. The detail is coming back. Notice also that due to the sun from the side, relief in the leaf cover is very visible. This is a great property if you are taking pictures of mountains; a sun from the side of the mountain will reveal substructures on mountains (smaller peaks, grooves, ridges etc.)

histogram6
One hour before sunset. The blue in the sky is back and shadow side becomes brighter.

histogram7
Half an hour after sunset. The sky is still fairly bright. The whole picture has a bluish look. This is also because the west north-western sky is blocked by a building. This means that the much redder light from the western sky is not reaching the chimney. I think that is there was no building there, the picture would look redder.

histogram8
Past midnight. Sun is gone and the moon is up. The bright stripes in the sky are stars, making their progression through the night sky.

Summary
This assignment made it very visual to me how the different kinds of sunlight at different time of day affect an photo. Remember that the photos above are all of the same thing, with the same camera and from the same position, the only thing that changed was the sun! One thing I also learned was that a morning looks different than an evening and it might very well be worthwhile waking up early to take some photos.

  • Both the direction, colour and strength of sunlight determine how a picture looks
  • Sun from the side reveals relief in the surface
  • Morning brings out more vibrant colours.
  • Midday creates large contrasts between lit and shaded areas and a lot of detail is lost.

Hope this was useful to you and let me know if you have any additions or comments in the comment section. Happy shooting!

Bag review LowePro compudaypack

5 07 2009

LowePro compudaypackIn this review I will talk about my camera bag, the LowePro compudaypack (see product site here)
Specs:
The bag ha 3 main compartments: Camera, General and Laptop. Each compartment has its own zipper. The camera part has six compartments which can be rearranged to fit your gear. The longest lens which fits into a single comportment is about 18 cm. The laptop part is design to hold a 15″ laptop. The other compartment is fairly spacious and can hold your lunch, extra sweater etc.

My impressions:
When I set out to find my camera bag I had 2 requirements and 1 nice to have:

  • Should hold all my camera gear for the foreseeable future
  • When I go hiking I should be able to fit the rest I bring in the same bag (coat, lunch, book etc etc)
  • Nice to have: ability to fit my laptop in so it can function as my airplane carry on luggage

Based on these requirements I choose this bag, and I am definitely happy with it. The first requirement is easy to fill, many bags carry all the gear I have or was planning to buy in the foreseeable future. This gear is a nikon D60, 18-55 lens, 50mm lens, 70-300 lens, small stuff (battery, lenspen etc).

The second requirement was harder. Most bags which will carry the gear won’t carry much else. If you are going on a hike or short trip this means that you will need to carry two bags around. The LowePro was one of the few which had a good size camera part, but also room for other stuff and even a special laptop compartment for if your laptop needs to join you.

The bag is also comfortable to wear. I took it with me for long hikes in the Swiss alps (easy tracks though :) ) and walked all day with it through San Francisco and I didn’t have any problems with it.
The only limitation I found was that the lens which is mounted to the camera body can’t be too long. I would have preferred to be able to mount my 70-300 while the camera is in the bag, in case an animal shows up unexpectedly.
Tripod:
The tripod I have (manfrotto 785shb) also fits into the bag. It fits nicely in the top compartment. To optimise the space I have the ballhead sticking out, but this is not required.

    pro’s

  • Large enough camera compartment
  • large enough space for other stuff
  • comfortable to wear
    con’s

  • longer lenses won’t fit (over 16cm)
  • Camera mounted lens can only be 10 cm

A good bag is important as it determines what gear you will have with you when you go out to shoot. I can recommended this bag without hesitation.

Happy shooting!
