Department of redundancy department

Today’s post is all about redundancy. Today’s post is all about redundancy. Okay, I think I’ve beaten that joke to death. Seriously though, I’ve already hit on RAID and that is one form of redundancy but when you’re running a business and time is money there’s still a lot more to think about in terms of redundancy.

Dispelling the 72 dpi myth

I first wrote my article explaining the difference between DPI and PPI around 10 years ago. To put it in perspective, it originated as a post on Usenet. I posted that article mainly to help clear up the difference in the terms because I was frequently seeing them misused. Way back then I’d always planned a follow-up article on what I like to call the “72 dpi myth”. This week’s Tech Tuesday instalment seems as good a time as any to finally complete the follow-up piece to that article.

Rollback

What do you do when a “routine” upgrade goes bad? How about a “minor” change to your website that breaks the whole site? How quickly can you recover? Can you even recover? This week’s Tech Tuesday feature is all about rollback options.

I’ve spent the last few weeks talking about back-up options. That’s a topic that should already be pretty familiar to most people. This week I want to talk about something that’s probably a littler further afield for most photographers and other small business operators, the concept of rollback.

Mirrors, snapshots and incremental back-ups

Following up on the back-up theme from last week’s Tech Tuesday post, RAID is not Back-up, I’m going into a little more depth on some back-up options and what each of them offers. This week I want to talk about 3 very popular options; mirrors, snapshots and incremental back-ups.

RAID is not back-up

Decided to try something new with the blog part of my site. My day job is in IT so I decided to start doing some technology posts with a photography slant. Trying to get into the habit of blogging more often so as part of that I’m going to see if I can make this a weekly feature for the site. I’m going to call this series “Tech Tuesdays”. The goal is to have something new posted every Tuesday.

For the next couple of weeks I’d like to hit on storage and back-up and how to protect your photos. So with that in mind, I’m kicking this series of with RAID is not back-up. I’ve seen several cases where people mistakenly thought that they didn’t need to back-up their data because they have that data on a RAID system and I wanted to clear up what a RAID is for and why you still need a proper back-up strategy.

Getting a shot out of your head

2011-04-25_halifax_0016-edit
A bit of a random image this time. This is about a block from my house and a couple of weeks ago when I was on a walk I spotted the wall and the fire hydrant and I just knew I had to shoot it. It’s kind of hard to explain but I could just so perfectly see this shot in my mind and I couldn’t get it out.

Backyard BBQ

2011-04-12_backyard-bbq_0020

Continuing with my experimenting with food photography I recently took my camera out while grilling some steaks on my Weber charcoal BBQ. All of the food is real, as is the fire. And in case anyone is wondering, I have no relationship with Weber or any charcoal companies. I do happen to think that Weber makes a pretty good grill though.

Making Montreal, pt. 2

This is part 2 of my how-to series on how I did the post-processing on my Montreal images. If you haven’t already read part 1 then I strongly recommend starting there first.

Camera Raw

1-original_effect 2-global_acr As mentioned in part 1, the first piece of flexibility you get with this workflow is in being able to re-visit your raw developing settings after you see the effect. This first image shows what the initial effect looked like for this particular image. In this case, I was very happy with the black and white image but I wanted to adjust things after I saw the effect. In this case, I liked what I was seeing in the mix of cold and warm light from taking this shot relatively early in the morning and I wanted to emphasize that further.

Since I was working with a smart object, this is a simple matter of opening the smart object from the layers palette which puts you back into Adobe Camera Raw. The one downside I found with this workflow is that I much prefer working in Lightroom and while the adjustments in Camera Raw are the same the interface isn’t so I do find I’m not as efficient working in Camera Raw. In this case though, I simply made some modifications to the saturation for the blues and the yellows.

3-after_acr 4-local_acr This produced the second image shown here. Overall, I was happy with the look but I found that in some specific areas things had gotten a little too blue and I wanted to tone that down. Again, I was able to go into Camera Raw and make some adjustments, this time, I used an adjustment brush to reduce the saturation in the areas I wasn’t happy with.

While not shown here, I also tried further adjustments to the saturation, vibrance and colour temperature before arriving at the settings used in this case. The point is that you still have all of your raw developing tools available to you. The one caveat is that the preview in Camera Raw will only show its effects, it won’t show the effect of the filter. This means that sometimes you have to make a change and then hit okay in order to see what it will look like with the smart filter applied. Once you get more familiar with what you’re trying to achieve and how the colour and black and white are interacting this will get easier.

Silver Efex Pro 2

5-original_effect For this second image I was happy with the colour in the image but there were some things I wanted to tweak in the black and white conversion after I saw the effect. Again, this is where working with smart filters really comes in handy as you can always get back into the settings and adjust. I find this is much easier than having to undo the filter and then re-apply it, especially if you want to work iteratively by making small changes and seeing the effect. Once you get the feel for the image and how the black and white effect is working with the image you can start targeting the shortcomings more precisely and you may not have to move back and forth as often.

In the case of this image, I was relatively happy with parts of the image but I wasn’t happy with the snow in the sky looking too dark (in several spots they were dark grey blobs instead of white flakes) and I felt that the top of the skyscraper was too faded out. In this case, I used Silver Efex Pro’s “U-Point” technology to add several control points to adjust this. First, I brought down the flakes in the sky so that they faded away more. After that I darkened the top of the building to make it more prominent. This also had the fortunate side effect of isolating the top of the building from the effect in the sky. After that I worked on adjusting the church to even out the exposures so that it was neither too dark nor too light. I also made some adjustments in the tree on the right side of the image as I felt it was blending in too much with the church and getting lost. Adjusting the black and white conversion helped give the separation I was looking for.

6-u-points As you can see from the screenshot in Silver Efex, I made significant use of the control points to get to the final image. What’s nice is that all of these can be tweaked either in groups or independently. I can also turn off any of the points at any time or delete them entirely. That’s definitely one of the huge perks to working with a plug-in that gives this much versatility and control.

As I made such an extensive use of control points in this image I’ve decided not to include images from every step. Since this is a 3rd party plug-in I also didn’t want to get too bogged down in the specifics of using this one plug-in. The point though is that you can adjust the black and white conversion to suit your purposes. In some cases you need to get past the fact that the goal is not necessarily to produce a pleasing black and white image, the goal is to produce a pleasing effect with the colour. In some cases this means making changes to the black and white that don’t work for that but do work once the colour is added.

Final Notes

One final note about this if you’re working with Lightroom, I highly recommend not making further adjustments in Lightroom after applying this effect. The reason for this is that if you want to go back into Photoshop to adjust your effect later then you won’t be able to take these Lightroom edits with you. The reason for this is that if you chose to edit in Photoshop with the Lightroom adjustments then you’ll get a brand new image created (as either a TIFF or PSD file, depending on your preferences) which will not retain the smart objects or smart filters from before. Instead, you need to use “edit original” if you want to get back to your original PSD document with these still available. This is a little counter-intuitive and not how you would normally edit images from Lightroom so I wanted to make sure to mention it here.

1-before_and_after A little later than I’d hoped but here’s part one of my promised how-to on how I achieved the “edgy” look I was so pleased with in my Montreal shots. (more…)

Montreal: more exprimentation

2011-02-26_montreal_0039-edit-2

I was in Montreal for a few days around the end of February. While the purpose of the trip wasn’t for photo I did manage to grab a couple of shots. I hadn’t shared them before as I was struggling with getting a good look that I was happy with.
