Hi Kent

Thanks for taking time to write your blog. Its over the top.

If you could also post some 'before' and 'after' shots to your 2 min tips that would be more than great.

Hey anonymous,

Sorry to hear you felt the podcast was boring. Do you have any suggestions on how to perk it up a bit? I'm always looking for ways to improve the show, and any suggestions are always welcome.

A neat trick which I will definitely try. Do you use Lab mode much in your work flow? Photoshop books, while praising its usefulness, always seem to mention Lab in a by-the-way manner.

I don't think it is boring at all. If you are interested in the subject it very helpful and useful.

I use Photo Elements 3.0 and would like to see how your tips work there, if it is possible.

Keep up the great work!

Hey Rachel,
I'm sure there are all kinds of neat things you can do in the LAB color mode, but honestly this is pretty much the only thing I do with it on a regular basis. If you (or anyone else) finds any neat tricks with LAB color mode, let me know and I'll share them on the site.

Thanks for listening,

Hey Alan,
Thanks for the kind words, it always great to hear from people who are enjoying the podcast and are learning from it too.

As far as how some of these tricks work in Photoshop Elements 3.0 I honestly couldn't tell you. I don't have a copy of Elements so it's nearly impossible for me to test the tricks out on it. I would imagine that some of the tips here would work on Elements, while others wouldn't. I would recommend browsing through all the menus and options in Elements to see if you can find the same or similar ones we use on the show. If you can find them, these tricks would work. Sorry I can't be much more help.

Thanks for listening,

Hello Garg,

Thanks for the great review and the link. I was surprised to read in your review that the show had cracked the top 50 list in the iTunes podcast directory. I hadn't even though to check the list, but as I write this I see the show is #40. Needless to say I was pleasantly surprised.

Thanks for listening,

Don't take this the wrong way, cuz i love your podcast...

I didn't notice much of a difference between the before and after example you showed. Sure it looks a little bit better, but not a huge difference.

Keep up the show. and when are you going to pick things up and post 2 shows a week? :)

Hey Bobthony,
You are right, the difference between the before and after shots on the front page are hardly night and day, but to my eye there is still quite an improvement. The difference might have been larger if this was shot with a different camera. The camera I use is known for its fairly low noise at high ISOs. Also, when I shot these images I believe I had the in camera noise reduction set to on. So had there been more noise to start with the difference might have been greater.

A lot of point and shoot cameras have very small CCD or CMOS chips (the sensor for recording images in a camera) and if you combine a small chip with a large number of mega pixels you often get noisier images- especially in low light situations. So hopefully this trick will work better with these types cameras.

I am looking into adding another show per week in a slightly different format, but I have been really busy lately so I’m not making any promises on more shows just yet. Keep your eyes open though.

Thanks for listening,
