'Good morning Greg. I trust you got home safely. Eric and I had an uneventful journey home. Surprisingly, Eric found his extender in his camera bag! Thanks for being such an incomparable guide and company. See you in February, if not before (maybe October).'

'Dear Greg, the training and experience with you has been even better than we expected. You bring out the best of Africa as you teach us each day to appreciate the animals and capture the best moments with pictures. You are patient and professional and we look forward to another journey with you. Best to you, Bob 'the camera caddy' and Jacquie.'

'Greg, thanks so much for the outstanding private safari in the Okavango Delta, Botswana that you led for us. The itinerary that you and C4 Photo Safaris developed gave us a terrific mix of magical Delta experiences, with fine camps and excellent local guides. The most important ingredient in this terrific experience, however, was you. On the photographic front, we were inspired by your commitment to artistic creativity and excellence, as well as ethical practices, in the capturing of wildlife images and greatly appreciated your graciously shared world class photographic expertise. We were delighted to find that you are also a knowledgeable naturalist, with wide-ranging expertise and engaging stories (and a voluminous reference library on your phone!) about both the fauna and the flora of Africa. We were encouraged by your commitment to conservation and especially to the Rebuilding the Pride project run by Masai landowner group SORALO in the South Rift Valley of Kenya. We look forward eagerly to joining you in the Masai Mara next year and in the South Rift Valley in 2018!'

'Hi Greg, It was a great pleasure to again share a photo safari with you. I saw some great things and picked up a few more tips on how to improve the technical aspects of my photography. While I aspire to take photos that are as good as yours, it would probably take a miracle to achieve it!! Hopefully I will be able to join you on more safaris in the future and continue my Canon education. Warm regards, Graham'

'Hi Greg! I wanted to tell you that I had the most incredible time on our African safari. I have such a hard time explaining the experience to my friends, since no words ever seem to do it justice. It was far beyond terrific! I am in the process of writing a review for you, which I hope to have done sometime soon. I have the same problem with the review, as I do describing the trip: no words ever seem fantastic enough.'

'Greg, Thank you for making possible an unending number of opportunities for us to be part of African nature and wildlife experiences that have have changed our lives and touched our souls. We anxiously await our next adventure with you. With our sincere and heartfelt thanks, Clinton and Rae-Anne Jammer.'

'Our safari exceeded our expectations! Greg's companionship, leadership & instruction was outstanding. It was clear that he engaged the best drivers in Bashi & Roan. They amazed us in their ability to find wildlife & the lengths to which they go to ensure we were in the right spot. We appreciated his "bush school" where he reiterated basic photography techniques. His reminders of the starting point settings while on location was also very helpful. We also had great fun photographing predators by spotlight & flash. He even taught us to photograph the night sky. Greg, I hope we can travel with you again in East Africa. Words cannot express how happy & excited we are with you, your team & our images!'

'I have done numerous safaris in Africa, in fact this was my twentieth over a period of about 15 years. And it was absolutely one of the very best. The quality of the sightings and the photographic opportunities they gave us was superb. Greg was the perfect guide, host and tutor, having time for everyone, his tutorials in the middle of the day were very well presented. In particular his special use of flash in certain situations was a revelation to me. All in all a fantastic experience, and for wildlife photographers a must-do safari.' (See a gallery of photos that Richard took on his safari here...)

'Thanks so much for the amazing trip to Shompole and the Masai Mara. The photographic opportunities are just too many to capture. Add the big five in 24 hours, with the accompanying wonderful birdlife and beautiful landscapes, all filled with light and sounds. We appreciate you sharing these very special places and your knowledge with us, particularly your photography advise as it has allowed us to start to capture the wildlife in a way that begins to do their wild beauty, life and land some justice.'

'I thoroughly enjoyed this trip, we set out to do something off the track and you delivered in spades. Amboseli was magical, especially the time we spent with Tim the tusker! The South Rift was special on so many fronts, as a geologist, as a photographer and as a human being - seeing the work that Samantha, Guy and others are doing to help protect a working model of human-wildlife coexistence, to help preserve a way of life while helping to guide it into the future and to educate the residents of the valley and those around the world interested in this magical corner of Africa was something I will never forget, and of course finishing up with a photographic feast in the Mara was the cherry on the cake. I think this some of my best work to date and I attribute this to your tutelage, your inspiration and your willingness to share your view of Africa with me, thanks my friend.'

'Hi Greg, we safely back in Denmark we just want to thank you so much for another incredible trip. It has been just amazing and we have really enjoyed your company, all your stories, all your knowledge, especially on birds. Me in particular, all your photographic advice on settings, composition, light etc. which has resulted in some great photos. We are already looking forward to our next trip in May next year.'

'It was a great pleasure to discover that Greg is an outstanding naturalist and birder as well as a world-class photographer. Birders and naturalists who lack an interest in photography would certainly be interested in Greg's other skills. Greg played a very large role in assuring the success of our Safari in many ways.'

'Our experience on this trip has far exceeded each of our expectations. The abundance and diversity of wildlife in Masai Mara was spectacular (ranging from some serious herds of wildebeest and zebras, prides of lions, cheetahs, leopards, elephants, giraffes and a rhino etc), providing numerous photographic opportunities. We also witnessed impressive crossings of wildebeest and zebras. Greg was great not only because of his wealth of knowledge in wildlife, he also gave invaluable advice as to how to best capture the amazing scenes happening in front of us from both a technical perspective and also a art/creative perspective. He was generous to share with us his take on different subjects on location, and his award-winning technique and creativity. The camp selection and the guides at the camps were great (the guides had eagle-eyes to spot animals from a serious distance). All in all, it was a great trip and we hope to come back to Africa as soon as we can!'

We would like to thank you for the great predator trip to Kenya, with the extension to Amboseli. From the beginning to the end, you managed to get us into the right spot at the right time. Your dedication to the bush and the animals was extraordinary. On every game drive we could be sure that you would give your best ing terms of getting us to the predators, especially to the cats. We managed to get to some amazing sightings with the big cats and elephants! Especially at Amboseli we felt the dedication in searching the big tusker and on our first day, shortly after we landed on the airstrip, and we succeeded to see Craig - the second biggest tusker in Amboseli. A dream come true! The lodges were well chosen and in amazing surroundings. What makes the trip with you special and productive is the fact that you know the places and the people (drivers) very well. This small, but key-factor, gave us some amazing encounters with lions, leopards an elephants. It was an mind-blowing experience to travel with you and we hope that you will see us again in the future. If you are looking for a down-to-earth person, that is connected to the bush and the animals, and if you want to see nature through his eyes and through your camera, Greg is THE ONE. Thank you for this amazing trip!

'Many thanks for a wonderful trip to Tanzania, it could not have been better. It was as if we had the crater and the plains all to ourselves, with all their wonders in most splendid view, along with great lodgings too. I thought your passion for what you do shone through magnificently, it inspired me. Fantastic to see you wielding your camera so expertly accompanied with your brilliant and timely suggestions as to what the best shot might be. The company was great, your colourful stories, excellent guiding, your encyclopaedic wildlife and photography knowledge, which rounded things off perfectly.'
